Cymbalta is a prescription medication that’s FDA-approved to treat several conditions.

In adults, Cymbalta is approved to treat:

In children, Cymbalta is approved to treat:

  • GAD in kids ages 7 years and older
  • fibromyalgia in kids ages 13 years and older

For more information about how Cymbalta is used to treat these conditions, see the “Cymbalta uses” section below.

Drug details

Cymbalta contains the active drug duloxetine. Duloxetine belongs to a drug class called serotonin-norepinephrine reuptake inhibitors (SNRIs). A drug class is a group of medications that work in a similar way.

Cymbalta comes as a capsule that you take by mouth. The capsules are available in three strengths: 20 milligrams (mg), 30 mg, and 60 mg.

Effectiveness

For information on the effectiveness of Cymbalta, see the “Cymbalta uses” section below.

Cymbalta is available as a generic drug called duloxetine. A generic drug is an exact copy of the active drug in a brand-name medication. The generic is considered to be as safe and effective as the original drug. Generics tend to cost less than brand-name drugs.

If you’re interested in using the generic form of Cymbalta, talk with your doctor. They can tell you if it comes in forms and strengths that can be used for your condition.

Cymbalta can cause mild or serious side effects. The following lists contain some of the key side effects that may occur while taking Cymbalta. These lists don’t include all possible side effects.

For more information on the possible side effects of Cymbalta, talk with your doctor or pharmacist. They can give you tips on how to deal with any side effects that may be bothersome.

How long do side effects from Cymbalta last?

How long side effects from Cymbalta last can vary depending on the side effect.

Also, your risk for certain side effects may be higher when you first start taking the drug. For example:

  • Your risk for suicidal thoughts or behaviors may be highest in your first few months of taking Cymbalta or after your dose is changed. However, this can occur at any time while taking Cymbalta.
  • Your risk for orthostatic hypotension (changes in blood pressure that could lead to falls) may be highest in your first week of taking Cymbalta.

Some side effects may go away once the drug is stopped. However, other side effects, like liver failure, may not go away if you stop the drug.

If you have questions about your risk for side effects with Cymbalta, talk with your doctor or pharmacist.

Side effect details

You may wonder how often certain side effects occur with this drug. Here’s some detail on certain side effects this drug may cause.

Allergic reaction

As with most drugs, some people can have an allergic reaction after taking Cymbalta. Symptoms of a mild allergic reaction can include:

  • skin rash
  • itchiness
  • flushing (warmth and redness in your skin)

A more severe allergic reaction is rare but possible. Symptoms of a severe allergic reaction can include:

  • swelling under your skin, typically in your eyelids, lips, hands, or feet
  • swelling of your tongue, mouth, or throat
  • trouble breathing
  • blisters
  • peeling rash

It’s not known how often allergic reaction occurred in people taking Cymbalta in clinical trials.

Call your doctor right away if you have a severe allergic reaction to Cymbalta. Call 911 or your local emergency number if your symptoms feel life threatening or if you think you’re having a medical emergency.

Weight gain and weight loss

In clinical studies of Cymbalta, weight gain and weight loss weren’t reported in adults. However, weight loss was a common side effect in children who took the drug in clinical studies.

In clinical studies of children with fibromyalgia:

  • 15% of children who took Cymbalta lost 3.5% or more of their body weight
  • 5% of children who took a placebo lost 3.5% or more of their body weight

While taking Cymbalta, your child’s doctor will monitor their weight to make sure it stays in a healthy range for their age. If their doctor has any concerns with your child’s weight, they may have your child try a different medication to treat their condition.

If you have questions or concerns about weight gain or loss while taking Cymbalta, talk with your doctor.

Sexual side effects

Some people may experience sexual side effects while taking Cymbalta. The drug belongs to a class of medications called serotonin-norepinephrine reuptake inhibitors (SNRIs). These medications are known to sometimes cause sexual side effects.

It’s important to note that conditions such as major depressive disorder (MDD) and generalized anxiety disorder (GAD) can cause changes in libido (sexual drive) or performance. Therefore, it can be hard to tell if these side effects are caused by Cymbalta or by the condition the drug is treating.

While taking Cymbalta, your doctor may ask about any sexual side effects you may be experiencing. And if you notice sexual side effects while taking Cymbalta, talk with your doctor. They may recommend a different medication to treat your condition.

Study results

In clinical studies of adults with MDD or GAD:

  • 2% of people who took Cymbalta reported an abnormal orgasm, including anorgasmia (not being able to orgasm)
  • less than 1% of people who took a placebo reported an abnormal orgasm, including anorgasmia

The researchers didn’t note how often this side effect occurred in women compared with men.

In clinical trials of adults with MDD or GAD:

  • 3% of people who took Cymbalta had decreased libido
  • 1% of people who took a placebo had decreased libido

The researchers didn’t note how often this side effect happened in women compared with men.

Sexual side effects in men

In clinical studies, men who took Cymbalta experienced more sexual side effects compared with men who took a placebo (a treatment with no active drug). The results showed that:

  • 4% of men who took Cymbalta reported erectile dysfunction, compared with 1% of men who took a placebo
  • 2% of men who took Cymbalta reported delayed ejaculation, compared with 1% of men who took a placebo

Researchers also found that men who took Cymbalta reported more sexual dysfunction compared with men who took a placebo.

Sexual side effects in women

Clinical studies found that women who took Cymbalta and those who took a placebo seemed to have a similar level of sexual dysfunction.

Digestive problems

Digestive problems can occur with Cymbalta. In clinical studies:

  • 23% of people who took Cymbalta had nausea, compared with 8% of people who took a placebo (a treatment with no active drug)
  • 9% of people taking Cymbalta had constipation, compared with 4% of people who took a placebo
  • 9% of people who took Cymbalta had diarrhea, compared with 6% of people who took a placebo

If you experience digestive problems while taking Cymbalta, talk with your doctor. They may recommend treatment to relieve this side effect. Or they may have you try a different medication to treat your condition.

Insomnia

Some people may experience insomnia (trouble sleeping) while taking Cymbalta. In clinical studies:

  • 9% of people taking Cymbalta had insomnia
  • 5% of people who took a placebo had insomnia

With insomnia, you can have trouble falling asleep or staying asleep. It can cause you to wake up too early. If you experience sleep issues while taking Cymbalta, talk with your doctor. They may suggest ways to manage this side effect. Or they may have you try a different medication to treat your condition.

Headache

Headaches can occur while taking Cymbalta. In clinical studies:

  • 14% of people taking Cymbalta had headaches
  • 12% of people who took a placebo had headaches

Headache can also be a symptom of hyponatremia (low sodium levels). This is a serious side effect that can occur with Cymbalta. For this reason, call your doctor if you experience headache while taking Cymbalta. Your doctor can determine the cause of your headaches. They may also decide to have you try a different medication for your condition.

Suicidal thoughts and behaviors

Like other antidepressants, Cymbalta may raise your risk for suicidal thoughts and behaviors. Cymbalta has a boxed warning for this side effect. (A boxed warning is the most serious warning from the FDA.)

Clinical studies have shown antidepressants increase the risk of suicidal thoughts and behaviors in children and young adults ages 24 years or younger. It’s thought that this risk is highest in the first few months of treatment with Cymbalta or after your dose has been changed.

In people ages 65 and older, antidepressants can actually reduce the risk of suicidal thoughts and behaviors.

During your treatment, you should watch closely for any new or sudden changes in your behavior, feelings, moods, or thoughts. Also ask your family members, caregivers, and healthcare providers to look for changes in your behavior or moods. Call your doctor right away if you or someone else notices any changes.

Also, if you experience any of the following feelings or symptoms, call your doctor right away:

  • aggressive or violent behavior
  • anxiety or depression that’s new or gets worse
  • mania (extreme increases in activity or talking)
  • feeling very restless, agitated, or irritated
  • panic attacks
  • thoughts about suicide or dying
  • other unusual changes in your behavior or mood

Suicide prevention

If you know someone at immediate risk of self-harm, suicide, or hurting another person:

  • Ask the tough question: “Are you considering suicide?”
  • Listen to the person without judgment.
  • Call 911 or the local emergency number, or text TALK to 741741 to communicate with a trained crisis counselor.
  • Stay with the person until professional help arrives.
  • Try to remove any weapons, medications, or other potentially harmful objects.

If you or someone you know is having thoughts of suicide, a prevention hotline can help. The National Suicide Prevention Lifeline is available 24 hours per day at 800-273-8255. During a crisis, people who are hard of hearing can call 800-799-4889.

The Cymbalta dosage your doctor prescribes will depend on several factors. These include:

  • the type and severity of the condition you’re using Cymbalta to treat
  • your age
  • other medical conditions you may have
  • other medications you take
  • how your condition responds to Cymbalta
  • side effects you experience from the medication

Typically, your doctor will start you on a low dosage. Then they’ll adjust it over time to reach the amount that’s right for you. Your doctor will ultimately prescribe the smallest dosage that provides the desired effect.

The following information describes dosages that are commonly used or recommended. However, be sure to take the dosage your doctor prescribes for you. Your doctor will determine the best dosage to fit your needs.

Drug forms and strengths

Cymbalta comes as a capsule that you take by mouth. The capsules are available in three strengths: 20 milligrams (mg), 30 mg, and 60 mg.

Dosage for depression

The recommended starting dose for treating depression in most adults is 40 mg (20 mg twice a day) to 60 mg (either 30 mg twice a day or 60 mg once a day) per day. Your doctor may decide to start you on 30 mg per day before increasing to a higher dosage, however.

The maximum dosage of Cymbalta for treating depression in adults is 120 mg per day. However, it’s important to note that in clinical studies, researchers didn’t notice any benefit when the Cymbalta dose was increased above 60 mg per day. Because of this, the 120-mg dose isn’t recommended very often.

Dosage for anxiety

In adults younger than 65 years old, the recommended Cymbalta dosage for treating anxiety is 60 mg per day. Your doctor may decide to start you on 30 mg per day before increasing to this dose, however.

In adults ages 65 years and older, it’s recommended to start Cymbalta at a dose of 30 mg once a day. This dose should be continued for 2 weeks. After that, the dose can be increased to 60 mg/day.

The maximum dosage of Cymbalta for treating anxiety in adults of any age is 120 mg per day. However, it’s important to note that in clinical studies, researchers didn’t notice any benefit when the Cymbalta dose was increased above 60 mg per day. Because of this, the 120-mg dose isn’t recommended very often.

Dosage for diabetic nerve pain

Diabetic neuropathy is a painful condition resulting from nerve damage in people with diabetes.

For treating pain from diabetic neuropathy in adults, the recommended dose of Cymbalta is 60 mg once daily. Doses above 60 mg aren’t recommended for treating this condition.

Dosage for fibromyalgia

The recommended Cymbalta dosage for treating fibromyalgia in adults is 60 mg once daily. However, you’ll start by taking 30 mg once a day for a week. Then, assuming you respond well to the drug, your doctor will increase your dose to 60 mg once a day. Doses above 60 mg aren’t recommended for treating this condition.

Dosage for chronic musculoskeletal pain

The recommended Cymbalta dose for treating chronic musculoskeletal pain* in adults is 60 mg once daily.

You’ll start by taking 30 mg once daily for a week. Then, assuming you respond well to the drug, your doctor will increase your dose to 60 mg once daily. Doses above 60 mg aren’t recommended for treating this condition.

* With chronic musculoskeletal pain, you have ongoing pain in your bones, muscles, ligaments, nerves, and tendons.

Pediatric dosage

Cymbalta is approved to treat generalized anxiety disorder (GAD) and fibromyalgia in children.

Dosage for treating anxiety in children

For treating GAD in children ages 7 to 17 years old, the recommended dosage of Cymbalta is 30 mg once a day. This dose should be used for at least 2 weeks. After that, your child’s doctor can consider whether the dose should be increased to 60 mg per day.

The maximum dose for treating anxiety in children is 120 mg.

Dosage for treating fibromyalgia in children

For treating fibromyalgia in children ages 13 to 17 years old, the recommended Cymbalta dosage is 30 mg once a day. Your child’s doctor may increase the dosage to 60 mg once a day, based on how well your child responds to the drug.

Dosage questions

Below are answers to some questions you may have about taking Cymbalta.

What if I miss a dose?

If you miss a dose of Cymbalta, take your missed dose as soon as you remember. However, if it’s almost time for your next dose, just skip your missed dose and take your next dose as scheduled. You shouldn’t take two doses at once to make up for a missed dose. This may raise your risk for side effects from the drug.

To help make sure you don’t miss a dose, try using a medication reminder. This can include setting an alarm on your phone or downloading a reminder app. A kitchen timer can work, too.

Will I need to use this drug long term?

Cymbalta is meant to be used as a long-term treatment. If you and your doctor determine that Cymbalta is safe and effective for you, you’ll likely take it long term.

Cymbalta may cause withdrawal symptoms if the drug is stopped suddenly.

Withdrawal symptoms of Cymbalta can include:

Because of the risk of withdrawal symptoms, you shouldn’t abruptly stop taking Cymbalta. To help lower your risk for these symptoms, your doctor will gradually reduce your dosage over time. This is known as a drug taper.

There isn’t a recommended length of time your taper should last. The length of your taper may depend on the dose of Cymbalta you take and the condition it’s being used to treat.

There haven’t been studies on whether Cymbalta can cause drug dependence. Studies in rats didn’t show a risk of dependence, but animal studies don’t always predict what will happen in humans.

If you have additional questions about your risk for withdrawal or dependence with Cymbalta, talk with your doctor.

How long does Cymbalta stay in your system?

Cymbalta stays in your system for about 3 days. If you have questions about how long you’ll feel the effects of the drug, including potential withdrawal symptoms, talk with your doctor.

The Food and Drug Administration (FDA) approves prescription drugs such as Cymbalta to treat certain conditions. Cymbalta may also be used off-label for other conditions. Off-label use is when a drug that’s approved to treat one condition is used to treat a different condition.

Cymbalta for depression

Cymbalta is FDA-approved to treat major depressive disorder (MDD). With this condition, you may feel sadness, loss, or anger that interferes with your daily activities.

Symptoms of depression can vary from person to person. However, some common symptoms include:

  • digestive problems
  • feeling tired easily
  • not being able to concentrate or complete tasks
  • loss of interest in activities you usually enjoy
  • mood changes, such as feeling irritable
  • sleeping problems (such as sleeping too much or too little)
  • thoughts of suicide or dying

The causes of depression aren’t fully known. It also isn’t known how Cymbalta works to treat depression. However, it’s thought that the drug changes the levels of certain chemicals in your brain that affect your mood and well-being.

Effectiveness for depression

Clinical studies have shown Cymbalta to be effective for treating depression.

One study compared daily use of Cymbalta with a placebo (a treatment with no active drug). The researchers used a tool called the Hamilton Depression Rating Scale (HAMD-17) to assess people’s depression before and after the study. If someone’s HAMD-17 score decreases, it shows an improvement in depression symptoms.

Scoring for the HAMD-17 works as follows:

  • 10 to 13 indicates mild depression
  • 14 to 17 indicates mild to moderate depression
  • Higher than 17 indicates moderate to severe depression

At the end of the study, the researchers found that

  • People who took Cymbalta reduced their HAMD-17 by 10.9 points. Before the study, the average HAMD-17 score in this group was 21.5.
  • People who took a placebo reduced their score by 6.1 points. Before the study, the average HAMD-17 score in this group was 21.1.

Cymbalta for anxiety

Cymbalta is FDA-approved to treat generalized anxiety disorder (GAD).

Almost everyone experiences anxiety at some point. It’s our body’s natural stress response. However, you may experience extreme feelings of anxiety, or anxiety that lasts longer than 6 months. If these feelings interfere with your daily life, you may have an anxiety disorder.

People with GAD have excessive anxiety that can occur frequently. Symptoms of GAD may vary but can include:

  • trouble concentrating
  • fast heart rate
  • rapid breathing
  • restlessness
  • trouble falling asleep

It isn’t known what causes GAD. It’s also not known how Cymbalta treats GAD. However, it’s thought that the drug changes levels of certain chemicals in your brain that affect your mood and well-being.

Effectiveness for anxiety

Cymbalta has been shown to be effective for treating generalized anxiety disorder (GAD).

One clinical study involved adults with GAD. Researchers first gave everyone Cymbalta for 26 weeks. People whose condition improved with the drug were then randomly chosen to either keep taking Cymbalta or switch to a placebo. (A placebo is a treatment with no active drug.) The people switched to a placebo didn’t know they were taking a placebo.

The researchers used the Hamilton Anxiety Scale (HAM-A) and the Clinical Global Impressions of Improvement scale to assess people’s anxiety before the study began. They used increases in these scores to determine when someone in the study had a GAD relapse.

In the study, a GAD relapse was defined as someone leaving the study because they felt their treatment wasn’t working. The researchers compared how long it took for people using Cymbalta to have a GAD relapse compared with people taking a placebo.

In the study:

  • it took 200 days for 20% of people taking Cymbalta to experience a GAD relapse
  • it took about 50 days for 20% of people taking a placebo to experience a GAD relapse

These results show that people taking Cymbalta had reduced anxiety symptoms for a longer period of time than people who took a placebo.

Cymbalta for diabetic nerve pain

Cymbalta is FDA-approved to treat pain from diabetic neuropathy (nerve damage).

Diabetic neuropathy is a common condition in people with type 1 and type 2 diabetes. People with diabetes have high levels of glucose (sugar) in their blood. Over time, having increased glucose levels can cause nerve damage. Symptoms of diabetic neuropathy include numbness, pain, tingling, or weakness in your hands or feet.

It isn’t exactly known how Cymbalta works to treat diabetic nerve pain.

Effectiveness for diabetic nerve pain

Clinical studies have shown Cymbalta to be effective for treating pain from diabetic neuropathy.

Researchers in one study randomly assigned adults with diabetic nerve pain to take either Cymbalta or a placebo every day for 12 weeks. Before the study, researchers measured people’s pain on a scale of 0 (no pain) to 10 (worst pain possible). They assessed pain again after the study to compare how Cymbalta and a placebo affected pain.

At the end of the study:

  • 60% of people who took Cymbalta had at least a 30% reduction in their pain score
  • 40% of people who took a placebo had at least a 30% reduction in their pain score

Cymbalta for fibromyalgia

Cymbalta is FDA-approved to treat fibromyalgia. This is a chronic condition that can cause:

  • areas of tenderness
  • cognitive issues
  • fatigue (lack of energy)
  • musculoskeletal pain (pain in the bones, muscles, ligaments, nerves, and tendons)
  • trouble sleeping

It’s not known what causes fibromyalgia. There aren’t tests to diagnose it, and its symptoms are similar to those of other conditions. Fibromyalgia is often misdiagnosed and can be difficult to treat.

It’s also not known how Cymbalta works to treat fibromyalgia.

Effectiveness for fibromyalgia

Clinical studies have shown Cymbalta to be effective at treating fibromyalgia.

One study compared Cymbalta with a placebo in adults with fibromyalgia. Before the study, these adults had an average pain score of 6.5 on a scale of 0 (no pain) to 10 (worst pain possible).

People in the study took either Cymbalta or a placebo every day for 6 months. The researchers then measured their pain scores again to see if there was any improvement.

At the end of the study:

  • about 40% to 50% of people who took Cymbalta had at least a 30% reduction in their pain score, depending on their dosage
  • about 20% of people who took a placebo had at least a 30% reduction in their pain score, depending on their dosage

Cymbalta for chronic musculoskeletal pain

Cymbalta is FDA-approved to treat chronic musculoskeletal pain. This refers to pain in the bones, muscles, ligaments, nerves, and tendons. Chronic pain is pain that lasts for more than 3 to 6 months.

It isn’t known how Cymbalta works to treat chronic musculoskeletal pain.

Effectiveness for chronic musculoskeletal pain

Clinical studies have shown Cymbalta to be effective for treating chronic musculoskeletal pain. These studies involved adults with chronic low back pain or chronic pain caused by osteoarthritis (a joint disorder that causes swelling and pain).

In one study, adults with chronic low back pain took either Cymbalta or a placebo every day for 13 weeks. Before the study, people rated their pain on a scale of 0 (no pain) to 10 (worst pain possible). The researchers had people rate their pain again at the end of the study.

The results showed that:

  • nearly 45% of people who took Cymbalta had at least a 30% reduction in their pain score
  • about 30% of people who took a placebo had at least a 30% reduction in their pain score

Cymbalta and children

Cymbalta is FDA-approved for use in children ages 7 years and older with generalized anxiety disorder (GAD). It’s also approved for use in children ages 13 years and older with fibromyalgia.

Clinical studies have shown Cymbalta to be effective for treating these conditions in children.

Here are answers to some frequently asked questions about Cymbalta.

Is Cymbalta an SSRI?

No, Cymbalta isn’t a selective serotonin reuptake inhibitor (SSRI). However, it’s similar to an SSRI.

Cymbalta belongs to a class of medications known as serotonin-norepinephrine reuptake inhibitors (SNRIs). It affects your levels of both serotonin and norepinephrine. SSRIs, on the other hand, only affect your serotonin levels.

If you have questions about whether an SSRI or SNRI is right for treating your condition, talk with your doctor.

Is Cymbalta a controlled substance? Is it a narcotic?

No, Cymbalta isn’t a controlled substance or a narcotic. “Narcotics” is another term for opioids, which are a type of pain reliever. Controlled substances are medications that could cause either physical or mental dependence. With dependence, your body needs the drug to feel normal. The Drug Enforcement Administration (DEA) sets limits on who can make, possess, and use medications that are controlled substances.

Animal studies of Cymbalta didn’t show dependence in rats, although animal studies don’t always predict what will happen in humans.

However, Cymbalta could cause withdrawal symptoms if you stop taking the drug suddenly. See the “Cymbalta withdrawal and dependence” section above to learn more.

Clinical studies didn’t show any signs that Cymbalta is addictive. Addiction is different from dependence. Addiction is a disease in your brain’s reward pathways. This disease leads someone to continue using a drug even though it’s causing serious problems in their life. Over time, someone with addiction needs more and more of a drug to feel its effects.

Although Cymbalta isn’t known to cause dependence or to be addictive, it’s not always possible to predict whether it could be misused. This is because the drug affects your central nervous system (CNS). The CNS is where your brain’s reward pathways (which can be involved with addiction) are located.

If you have questions or concerns about your risk for dependence with Cymbalta, talk with your doctor.

How does Cymbalta make you feel?

Cymbalta is approved to treat mood disorders, such as depression and anxiety. Because it affects your mood, some people report feeling calm or as if their mood is boosted while taking the drug.

Cymbalta doesn’t make you feel “high” or euphoric, like you may feel from using illicit drugs. If you have questions about how Cymbalta may affect you, talk with your doctor or pharmacist.

Does Cymbalta make you sleepy?

It’s possible that you’ll feel sleepy while taking Cymbalta. This was one of the more common side effects of the drug in clinical studies. In the studies:

  • 10% of people who took Cymbalta reported feeling sleepy
  • 3% of people who took a placebo (a treatment with no active drug) reported feeling sleepy

Because Cymbalta can cause sleepiness, it’s important to use caution or avoid driving or and operating machinery until you know how the drug will affect you.

If you have questions about side effects from Cymbalta, talk with your doctor or pharmacist. You can also learn more in the “Cymbalta side effects” section above.

You may wonder how Cymbalta compares with other medications that are prescribed for similar uses. Here we look at how Cymbalta and Lexapro are alike and different.

* Both Cymbalta and Effexor XR have a boxed warning for this side effect. This is the most serious warning from the Food and Drug Administration (FDA). See the “FDA warning: Suicidal thoughts and behaviors” section at the beginning of this article to learn more.

Effectiveness

Cymbalta and Effexor XR have different FDA-approved uses, but they’re both used to treat the following conditions:

  • major depressive disorder (MDD) in adults
  • generalized anxiety disorder (GAD) in adults

The use of Cymbalta and Effexor XR in treating depression in adults has been compared in a meta-analysis. A meta-analysis is a type of study that looks at the results of numerous clinical studies to see if there are any consistent results across the studies.

In this meta-analysis, researchers looked at 16 clinical studies comparing Cymbalta with other antidepressants, including three studies that compared Cymbalta with Effexor XR. The researchers found the two drugs to be similarly effective for treating depression.

A clinical study directly compared Cymbalta and Effexor XR for treating anxiety in adults. In this study, the researchers randomly assigned people to take either Cymbalta, Effexor XR, or a placebo (a treatment with no active drug) once a day for 10 weeks. The researchers used the Hamilton Anxiety Rating Scale (HAM-A) to measure people’s anxiety before and after the study.

At the end of the study, the researchers found that people who took Cymbalta or Effexor XR had improved HAM-A scores compared with those who took a placebo. They found Cymbalta and Effexor XR to be similarly effective for treating anxiety.

Costs

According to estimates on GoodRx.com, Cymbalta costs significantly less than Effexor XR. The actual price you’ll pay for either drug depends on your insurance plan, your location, and the pharmacy you use.

Cymbalta is available as a generic drug called duloxetine. Effexor XR is available as a generic drug called venlafaxine ER. A generic drug is an exact copy of the active drug in a brand-name medication. The generic is considered to be as safe and effective as the original drug. Generics tend to cost less than brand-name drugs.

Other drugs are available that can treat your condition. Some may be a better fit for you than others. If you’re interested in finding an alternative to Cymbalta, talk with your doctor. They can tell you about other medications that may work well for you.

Note: Some of the drugs listed here are used off-label to treat these specific conditions. Off-label use is when a drug that’s approved to treat one condition is used to treat a different condition.

Alternatives for chronic musculoskeletal pain

Examples of other drugs that may be used to treat chronic musculoskeletal pain (pain in the bones, muscles, ligaments, nerves, and tendons) include:

It’s possible that Cymbalta and alcohol can interact and cause damage to your liver.

On its own, Cymbalta has caused liver damage and liver failure. In rare cases, this liver damage was fatal. Liver damage wasn’t reported in clinical studies, but there have been reports of liver damage since the drug was first approved.

Cymbalta shouldn’t be used in people who drink excessive amounts of alcohol. That’s because excessive alcohol use can also damage your liver over time. Therefore, drinking heavily during your Cymbalta treatment could raise your risk for liver damage even more. For more information, see “Liver or kidney problems” in the “Cymbalta precautions” section below.

If you drink alcohol, talk with your doctor before you start taking Cymbalta. Depending on the amount of alcohol you consume, they may decide to have you try a different medication for your condition.

In adults, Cymbalta is FDA-approved to treat:

In children, Cymbalta is FDA-approved to treat:

  • GAD in children ages 7 years and older
  • fibromyalgia in children ages 13 years and older

It isn’t known how Cymbalta works to treat any of these conditions. However, it’s believed that Cymbalta works by increasing levels of certain chemicals in your central nervous system.

Cymbalta belongs to a drug class called serotonin-norepinephrine reuptake inhibitors (SNRIs). A drug class is a group of medications that work in a similar way.

How long does it take to work?

Cymbalta begins working as soon as you take your dose. It takes about 3 days for levels of the drug to become stable in your body. Depending on the condition it’s being used to treat, it may take longer than this before you notice the full effects of the drug.

For example, in clinical trials, some adults with pain caused by diabetic neuropathy (nerve damage), as well as some adults with fibromyalgia, noticed improvement within 1 week of starting the drug.

However, the National Alliance on Mental Illness notes that full improvement of depression symptoms may take up to 8 weeks.

If you have questions about how Cymbalta works, or how long it takes to work, talk with your doctor or pharmacist.

Cymbalta can interact with several other medications. It can also interact with certain supplements.

Different interactions can cause different effects. For instance, some interactions can interfere with how well a drug works. Other interactions can increase side effects or make them more severe.

Cymbalta and other medications

Below are lists of medications that can interact with Cymbalta. These lists don’t contain all drugs that may interact with Cymbalta.

Before taking Cymbalta, talk with your doctor and pharmacist. Tell them about all prescription, over-the-counter, and other drugs you take. Also tell them about any vitamins, herbs, and supplements you use. Sharing this information can help you avoid potential interactions.

If you have questions about drug interactions that may affect you, ask your doctor or pharmacist.

Cymbalta and other drugs that affect serotonin (such as Adderall and tramadol)

Cymbalta can increase serotonin levels in your body. Using Cymbalta with other drugs that also increase serotonin may raise your risk for serotonin syndrome.

Serotonin syndrome is a rare but potentially life threatening condition. It’s caused by increased serotonin levels in your blood. Taking multiple medications that increase serotonin levels could cause serotonin to build up to dangerous levels in your blood.

Examples of other drugs that can increase serotonin levels include:

Before taking Cymbalta, be sure to tell your doctor if you take any of the medications listed above. They may want to monitor you for any signs of serotonin syndrome. Or they may have you take a different drug to treat your condition.

Drugs that inhibit CYP1A2 or CYP2D6

Certain medications inhibit (slow down) the activity of two enzymes, called CYP1A2 and CYP2D6. Taking Cymbalta with these drugs may increase Cymbalta levels in your body.

The CYP1A2 and CYP2D6 enzymes help your body break down drugs. Slowing down this process could raise your risk for side effects from Cymbalta.

Certain drugs have stronger effects on these enzymes. You shouldn’t use Cymbalta with medications that are considered strong CYP1A2 inhibitors. Examples of strong CYP1A2 inhibitors include:

  • cimetidine
  • ciprofloxacin (Cipro)
  • fluvoxamine (Luvox)

Drugs that inhibit the CYP2D6 enzyme may also affect Cymbalta levels. However, this interaction isn’t as serious as with CYP1A2 inhibitors. Examples of CYP2D6 inhibitors include:

  • fluoxetine (Prozac)
  • paroxetine (Paxil)
  • quinidine

Before you take Cymbalta, be sure to tell your doctor if you take any of these medications. They can determine which drug is the best fit for you.

Drugs that are metabolized by CYP2D6

Although Cymbalta is broken down by CYP2D6, the drug can also inhibit (slow down) this enzyme. This means it can affect the levels of other drugs that are also broken down by this enzyme.

This shouldn’t cause issues with most medications broken down by CYP2D6. However, some medications can cause side effects if their levels in your body are changed slightly. Examples of these drugs include:

  • tricyclic antidepressants, such as:
    • amitriptyline
    • imipramine
    • nortriptyline
  • certain drugs for irregular heartbeat, including:
    • flecainide
    • propafenone
  • thioridazine (should not be used with Cymbalta)

Before taking Cymbalta, talk with your doctor about all the medications you take. They can determine whether Cymbalta can be taken with your other medications.

Drugs that affect your blood’s ability to clot

Drugs that affect serotonin levels, such as Cymbalta, may increase your risk for bleeding. If Cymbalta is used with drugs that affect your blood’s ability to form clots, this may raise your risk even more.

Examples of drugs that affect your blood’s ability to clot include:

Before taking Cymbalta, tell your doctor if you take any of the medications listed above. They may monitor you more closely to see if you’re at risk for bleeding. This monitoring may include ordering blood tests. Or they may decide to use a different medication to treat your condition.

Cymbalta and herbs and supplements

You shouldn’t use Cymbalta with St. John’s wort. This is an herb that can be used to treat depression.

Cymbalta can raise your serotonin levels. Because St. John’s wort also increases serotonin levels, taking Cymbalta with this supplement may raise your risk for serotonin syndrome. For more information on serotonin syndrome, see the “Cymbalta and other drugs that affect serotonin (such as Adderall and tramadol)” section above.

Cymbalta and foods

There aren’t any foods that have been specifically reported to interact with Cymbalta. If you have any questions about eating certain foods with Cymbalta, talk with your doctor.

Cymbalta may cause harm to a developing fetus. However, more research is needed in this area.

Clinical studies of the drug have shown that taking it the month before delivery may increase the risk of severe bleeding immediately afterward (postpartum hemorrhage). However, other studies haven’t shown a clear risk for birth defects caused by Cymbalta.

The manufacturer of Cymbalta maintains a pregnancy registry. The registry tracks the results of pregnant people taking the drug. You can join this registry online or by calling 866-814-6975.

If you’re pregnant or planning a pregnancy, talk with your doctor before you take Cymbalta. You should also tell your doctor right away if you become pregnant while taking this drug.

You should take Cymbalta according to your doctor’s or healthcare provider’s instructions.

Cymbalta comes as a capsule that you take by mouth. You’ll take it either once or twice a day, depending on the condition you’re using it to treat.

When to take

You can take Cymbalta at any time of the day. However, you should try to take it around the same time every day. This helps make sure you have a consistent amount of the drug in your body.

The best time for you to take Cymbalta may depend on what you use the drug for and how often you take it each day. Your doctor can help you decide the best time for you to take Cymbalta.

To help make sure you don’t miss a dose, try using a medication reminder. This can include setting an alarm on your phone or downloading a reminder app. A kitchen timer can work, too.

Taking Cymbalta with food

Cymbalta can be taken with or without food.

Can Cymbalta be crushed, split, or chewed?

No, you shouldn’t crush, split, or chew Cymbalta capsules. You also shouldn’t open the capsules to mix them with food or liquids. Doing so may affect how well your body absorbs the drug. This could raise your risk for side effects or make the drug less effective.

Using more than the recommended dosage of Cymbalta can lead to serious side effects.

Do not use more Cymbalta than your doctor recommends.

Overdose symptoms

Symptoms of an overdose can include:

What to do in case of overdose

If you think you’ve taken too much of this drug, call your doctor. You can also call the American Association of Poison Control Centers at 800-222-1222 or use their online tool.

Generic version

Cymbalta is available in a generic form called duloxetine. A generic drug is an exact copy of the active drug in a brand-name medication. The generic is considered to be as safe and effective as the original drug. And generics tend to cost less than brand-name drugs. To find out how the cost of duloxetine compares to the cost of Cymbalta, visit GoodRx.com.

If your doctor has prescribed Cymbalta and you’re interested in using duloxetine instead, talk with your doctor. They may have a preference for one version or the other. You’ll also need to check your insurance plan, as it may only cover one or the other.

Depending on the condition it’s being used to treat, Cymbalta may be used alone or with other medications.

If you have questions about using other drugs with Cymbalta, talk with your doctor or pharmacist. They can review your medications and discuss treatment options with you.

Cymbalta may cause harm to a fetus. However, more research is needed in this area. If you’re sexually active and you or your partner can become pregnant, talk with your doctor about your birth control needs while you’re using Cymbalta.

For more information about taking Cymbalta during pregnancy, see the “Cymbalta and pregnancy” section above.

Cymbalta passes into breast milk, but it’s not known to cause serious side effects. However, there have been a few reports of drowsiness, poor feeding, and trouble gaining weight in infants exposed to breast milk containing duloxetine. (Duloxetine is the active drug in Cymbalta.)

If you choose to breastfeed while taking Cymbalta, you should watch for any trouble feeding or drowsiness in your child.

If you’re considering breastfeeding while taking Cymbalta, talk with your doctor. Together, you can weigh the risks and benefits of breastfeeding while taking the drug and discuss your other treatment and feeding options.

This drug comes with several precautions.

FDA warning: Suicidal thoughts and behaviors

This drug has a boxed warning. This is the most serious warning from the Food and Drug Administration (FDA). A boxed warning alerts doctors and patients about drug effects that may be dangerous.

Clinical studies have shown antidepressants such as Cymbalta increase the risk of suicidal thoughts and behaviors in children and young adults ages 24 years or younger. In people ages 65 and older, antidepressants can actually reduce this risk.

During your treatment, you should watch closely for any new or sudden changes in your behavior, feelings, moods, or thoughts. Also ask your family members, caregivers, and healthcare providers to look for changes in your behavior or moods. Call your doctor right away if you or someone else notices any changes.

Other precautions

Before taking Cymbalta, talk with your doctor about your health history. Cymbalta may not be right for you if you have certain medical conditions or other factors affecting your health. These include:

  • Heart problems, including high blood pressure. Cymbalta may increase your blood pressure. If you already have hypertension (high blood pressure) or other heart problems, you may not be able to take Cymbalta. Before taking this drug, tell your doctor about any heart problems you may have, including high blood pressure.
  • Diabetes. If you have diabetes, Cymbalta may make it more difficult to control your blood sugar. Tell your doctor if you have diabetes before you take Cymbalta.
  • Liver or kidney problems. Your liver and kidneys help clear Cymbalta from your body. If you have liver or kidney problems, Cymbalta levels could build up in your body. This could raise your risk for side effects. Before you take Cymbalta, tell your doctor about any liver or kidney problems you have.
  • Closed-angle glaucoma. Cymbalta can cause closed-angle glaucoma. If not treated right away, this condition can result in blindness. Some people are born with eye angles that are more narrow than usual, which could raise their risk for this side effect. If you’re unsure whether you have narrow eye angles, talk with your doctor. You can get an exam to determine your risk.
  • Seizures or convulsions. Cymbalta may cause seizures or convulsions. The drug hasn’t been studied in people with seizure disorders. Therefore, it isn’t known how safe the drug is to use in people with this type of condition. Tell your doctor about any history of seizures or convulsions before you take Cymbalta.
  • Bipolar disorder or mania. Cymbalta may cause a mixed, manic, or hypomanic episode in people at risk for bipolar disorder (such as people with mood conditions). Before taking Cymbalta, your doctor should screen you for bipolar disorder. If you have a history of bipolar disorder or mania, tell your doctor before taking Cymbalta.
  • Hyponatremia. Cymbalta can cause hyponatremia (low sodium levels). If you have hyponatremia or have had it in the past, talk with your doctor before you take Cymbalta.
  • Delayed stomach emptying. Cymbalta capsules contain a special coating that helps protect the drug against the acid in your stomach. If you have a condition that delays stomach emptying, such as diabetes, your stomach may break down this special coating. This could make the drug less effective. Before taking Cymbalta, tell your doctor if you have a condition that delays your stomach from emptying.
  • Bleeding problems. Drugs that affect serotonin levels, such as Cymbalta, may raise your risk for bleeding. If you have other conditions that cause bleeding problems, this risk may be even higher. Before taking Cymbalta, tell your doctor about any history of bleeding problems you may have.
  • Allergic reaction. If you’ve had an allergic reaction to Cymbalta or any of its ingredients, you shouldn’t take Cymbalta. Ask your doctor about other medications that may be better options for you.
  • Pregnancy. Cymbalta may cause harm to a fetus. For more information, see the “Cymbalta and pregnancy” section above.
  • Breastfeeding. Cymbalta passes into breast milk. Talk with your doctor about the risks and benefits of taking this drug while breastfeeding. For more information, see the “Cymbalta and breastfeeding” section above.

Note: For more information about the potential negative effects of Cymbalta, see the “Cymbalta side effects” section above.

When you get Cymbalta from the pharmacy, the pharmacist will add an expiration date to the label on the bottle. This date is typically 1 year from the date they dispensed the medication.

The expiration date helps guarantee that the medication is effective during this time. The current stance of the Food and Drug Administration (FDA) is to avoid using expired medications. If you have unused medication that has gone past the expiration date, talk to your pharmacist about whether you might still be able to use it.

Storage

How long a medication remains good can depend on many factors, including how and where you store the medication.

Cymbalta capsules should be stored at room temperature (77°F/25°C) in a tightly sealed container away from light. For short periods of time, Cymbalta may be stored between 59°F and 86°F (15°C to 30°C). Avoid storing this medication in areas where it could get damp or wet, such as bathrooms.

Disposal

If you no longer need to take Cymbalta and have leftover medication, it’s important to dispose of it safely. This helps prevent others, including children and pets, from taking the drug by accident. It also helps keep the drug from harming the environment.

This article provides several useful tips on medication disposal. You can also ask your pharmacist for information on how to dispose of your medication.

The following information is provided for clinicians and other healthcare professionals.

Indications

The FDA has approved Cymbalta for treating the following conditions:

Administration

Cymbalta comes as a capsule that’s taken orally. Cymbalta capsules are available in three strengths: 20 milligrams (mg), 30 mg, and 60 mg.

Depending on the condition it’s being used to treat, Cymbalta is taken either once or twice daily. It can be taken with or without food.

Mechanism of action

The exact mechanism by which Cymbalta treats MDD, GAD, diabetic neuropathy, fibromyalgia, and chronic musculoskeletal pain is not known.

Cymbalta is classified as a serotonin-norepinephrine reuptake inhibitor (SNRI). The active drug ingredient in Cymbalta, duloxetine, inhibits neuronal serotonin and norepinephrine reuptake. To a lesser extent, duloxetine also inhibits dopamine reuptake.

Pharmacokinetics and metabolism

Duloxetine’s elimination half-life is approximately 12 hours, and steady state concentrations are usually reached after 3 days. The drug is highly bound (> 90%) to plasma proteins. The effect of this on drug interactions is unknown.

Duloxetine is primarily hepatically metabolized via CYP1A2 and CYP2D6.

Food delays the time it takes for duloxetine to reach peak concentration, from 6 hours to 10 hours. However, this has no overall effect on maximum concentrations.

About 70% of duloxetine is excreted in the urine as metabolites.

Contraindications

Do not start Cymbalta in patients treated with MAOIs, including linezolid and intravenous methylene blue. This can increase the risk of serotonin syndrome.

Cymbalta is contraindicated for 14 days after stopping an MAOI intended to treat a psychiatric disorder.

Use of MAOIs within 5 days of stopping treatment with Cymbalta is also contraindicated.

Misuse, withdrawal, and dependence

Cymbalta can cause withdrawal if treatment is stopped abruptly.

Withdrawal symptoms of Cymbalta can include:

Counsel Cymbalta users that treatment should not be stopped without talking with their prescriber. Cymbalta should be gradually tapered to avoid discontinuation syndrome.

If someone experiences withdrawal symptoms during their Cymbalta taper, consider returning to the previously prescribed dose. Once withdrawal symptoms subside, the taper can be continued at a more gradual rate.

Storage

Cymbalta capsules should be stored at room temperature (77°F/25°C) in a tightly sealed container away from light. For short periods of time, Cymbalta may be stored between 59°F and 86°F (15°C to 30°C).

This medication should not be stored in areas where it could get damp or wet, such as bathrooms.
