Effexor XR is a brand-name prescription drug. It’s approved for use in adults with any of the following conditions:

  • major depressive disorder (MDD)
  • generalized anxiety disorder (GAD)
  • social anxiety disorder
  • panic disorder, with or without agoraphobia (fear of being in places where you could be trapped or helpless)

Effexor XR contains the drug venlafaxine in its extended-release (XR) form. An extended-release form of a drug slowly releases the active ingredient over a prolonged period of time.

Effexor XR belongs to a class of drugs called serotonin-norepinephrine reuptake inhibitors (SNRIs).

It comes as a capsule that’s taken by mouth once a day.

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

Weight gain or weight loss

Weight gain and weight loss have occurred in clinical studies of Effexor XR. However, it’s not known how common these side effects are.

Talk with your doctor if you’re concerned about weight gain or loss while taking Effexor XR.

Nausea

Nausea is a common side effect of Effexor XR. To find out how often this side effect occurred in clinical studies, see the drug’s prescribing information.

If you have nausea while taking Effexor XR, talk with your doctor or pharmacist about ways to minimize this side effect.

Insomnia

Insomnia (trouble sleeping) is a common side effect of Effexor XR. To find out how often this side effect occurred in clinical studies, see the drug’s prescribing information.

If you have trouble sleeping while taking Effexor XR, talk with your doctor. They can recommend ways to reduce this side effect.

Suicidal thoughts and behaviors in young people

There is an increased risk of suicidal thoughts and behavior in young people (up to 24 years old) who take antidepressants, including Effexor XR. This increased risk is seen in young people who have major depressive disorder or other psychiatric conditions. Effexor XR has a boxed warning for this side effect.

Young people starting Effexor XR should be monitored closely for worsening depression, unusual behavior, and suicidal thoughts and behavior.

Note: Effexor XR is not approved for use in children (younger than 18 years old).

Suicide prevention

  • If you know someone at immediate risk of self-harm, suicide, or hurting another person:
  • Call 911 or the local emergency number.
  • Stay with the person until professional help arrives.
  • Remove any weapons, medications, or other potentially harmful objects.
  • Listen to the person without judgment.
  • 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 a day at 1-800-273-8255.

Side effects in children

Effexor XR is not approved for use in children (under 18 years old).

Effexor XR can cause an increased risk of suicidal thoughts and behaviors in children (see “Effexor XR side effects” above). There are also other side effect concerns if children take this drug.

Weight loss in children

In clinical studies lasting 8 to 16 weeks, many children who took Effexor XR had a lack of appetite. This may have contributed to weight loss seen in children within the study.

Longer studies lasting up to 6 months showed that children taking Effexor XR did not gain as much weight as other children in the same age group. This was especially true in children under the age of 12 years old.

Slowed growth in children

In clinical studies, children who took Effexor XR grew in height more slowly than typical children in their age group. This difference in growth was more dramatic for children under the age of 12 years old than for those ages 12 years and older.

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

  • the type and severity of the condition you’re using Effexor XR to treat
  • other medical conditions you may have

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

Effexor XR contains the drug venlafaxine in its extended-release (XR) form.

Effexor XR comes as a capsule that’s taken by mouth. You take it with food.

It comes in three strengths: 37.5 mg, 75 mg, and 150 mg.

Dosage for major depressive disorder

The usual starting dosage of Effexor XR for major depressive disorder (MDD) is 75 mg once daily. The maximum dosage for MDD is 225 mg once daily.

However, daily dosages of 300 mg or higher may be needed to treat MDD in some people. This would be considered an off-label (nonapproved) use.

Dosage for generalized anxiety disorder

The usual starting dosage of Effexor XR for generalized anxiety disorder (GAD) is 75 mg once daily. The maximum dosage of Effexor XR for GAD is 225 mg once daily.

Dosage for social anxiety disorder

The standard dosage of Effexor XR for social anxiety disorder is 75 mg once daily.

Dosage for panic disorder

The usual starting dosage of Effexor XR for panic disorder is 37.5 mg once daily. After 7 days, the dosage can be increased if needed. The maximum dosage for panic disorder is 225 mg once daily.

What if I miss a dose?

If you miss a dose of Effexor XR, take it as soon as you remember. However, if it’s almost time for your next dose, skip the missed dose and take your next dose at its regular time. Never take two doses at once. This will raise your risk of serious side effects.

To help make sure you don’t miss a dose, try setting a reminder on your phone. A medication timer may be useful, too.

Will I need to use this drug long term?

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

Abruptly stopping treatment with Effexor XR can cause withdrawal symptoms. These symptoms can include:

  • anxiety
  • feeling agitated
  • confusion
  • flu-like symptoms
  • insomnia (trouble sleeping)
  • shakiness
  • diarrhea
  • nausea
  • vomiting

To avoid withdrawal symptoms, your dosage of Effexor XR should be tapered (gradually decreased) over several weeks. See “Common questions about Effexor XR” for more details about how to safely stop taking Effexor XR.

You shouldn’t drink alcohol while taking Effexor XR. This is because both Effexor XR and alcohol can cause sleepiness and trouble concentrating when taken separately. Drinking alcohol while taking Effexor XR could make these side effects worse.

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 Effexor XR, 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.

Effexor XR and children

Effexor XR is not approved for use in people under 18 years old.

In fact, the FDA has required the manufacturers of Effexor XR to include a boxed warning in the drug’s label. A boxed warning is the strongest warning required by the FDA. It is used to alert healthcare professionals and patients about the risk of serious side effects seen with the drug.

The Effexor XR boxed warning describes an increased risk of suicidal thoughts and behaviors in young people who take Effexor XR. The increased risk is seen in children under 18 years old and in adults ages 24 years old and younger. (All antidepressants carry this warning, not just Effexor XR.)

Effexor XR can interact with several other medications and cause false results for certain lab tests. 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.

Effexor XR and other medications

Below is a list of medications that can interact with Effexor XR. This list does not contain all drugs that may interact with Effexor XR.

Before taking Effexor XR, 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.

Drugs that should not be used with Effexor XR

Drugs that should not be used while you’re taking Effexor XR include:

  • MAOIs. You shouldn’t take Effexor XR with a type of antidepressant called a monoamine oxidase inhibitor (MAOI). If Effexor XR is taken with an MAOI, the risk for serotonin syndrome is very high (see “About serotonin syndrome” below). Examples of MAOIs include:
    • selegiline (Emsam, Zelapar)
    • phenelzine (Nardil)
    • tranylcypromine (Parnate)
    • isocarboxazid (Marplan)
  • Zyvox (linezolid). You shouldn’t take Effexor XR if you’re taking an antibiotic called Zyvox. Taking these drugs together can increase your risk for serotonin syndrome (see “About serotonin syndrome” below).

Drugs that can interact with Effexor XR

Taking Effexor XR with the following drugs can cause an interaction:

  • Adderall XR. Taking Effexor XR with Adderall XR (amphetamine salts) or other stimulant medications can increase your risk for serious side effects. In particular, it increases your risk of serotonin syndrome (see “About serotonin syndrome” below).
  • Certain antidepressants. Taking Effexor XR with certain antidepressants can increase your risk for serious side effects, including serotonin syndrome (see “About serotonin syndrome” below). Examples of antidepressants that can increase your risk for serotonin syndrome if taken with Effexor XR include:
    • sertraline (Zoloft)
    • paroxetine (Paxil)
    • citalopram (Celexa)
    • escitalopram (Lexapro)

    • duloxetine (Cymbalta)
    • levomilnacipran (Fetzima)
  • Certain migraine drugs. Taking Effexor XR with certain migraine drugs called triptans can increase the risk for serious side effects. In particular, it increases your risk for serotonin syndrome (see “About serotonin syndrome” below). Examples of triptans include:
    • sumatriptan (Imitrex, Onzetra Xsail, Tosymra, Zembrace Symtouch)
    • naratriptan (Amerge)
    • almotriptan (Axert)
    • frovatriptan (Frova)
    • eletriptan (Relpax)
    • rizatriptan (Maxalt, Maxalt-MLT)
    • zolmitriptran (Zomig, Zomig-ZMT)
  • Certain prescription pain relievers. Taking Effexor XR with certain prescription pain medications increases your risk for serotonin syndrome (see “About serotonin syndrome” below). These drugs are:
    • tramadol (Conzip, Ultram)
    • fentanyl (Abstral, Actiq, Duragesic, Subsys)

About serotonin syndrome

Serotonin syndrome is a serious reaction that happens when too much serotonin (a chemical produced by nerve cells) builds up in your body. Symptoms of serotonin syndrome can include anxiety, shakiness, fever, diarrhea, fast heartbeat, and seizures.

If you experience any symptoms of serotonin syndrome, tell your doctor right away. They may recommend that you stop treatment with any medication that may cause serotonin syndrome until your symptoms are treated.

Call 911 if your symptoms feel life-threatening or if you think you’re having a medical emergency.

Effexor XR and herbs and supplements

Below is a list of herbs and supplements that can interact with Effexor XR.

  • John’s wort. St. John’s wort is an herbal supplement that’s often used to improve mood. Taking Effexor XR with St. John’s wort can increase your risk for serotonin syndrome (see below).
  • Tryptophan. Tryptophan (also called 5-HTP) is a supplement used to improve mood and sleep quality. Taking Effexor XR with tryptophan can increase your risk for serotonin syndrome (see below).

About serotonin syndrome

Serotonin syndrome is a serious reaction that happens when too much serotonin (a chemical produced by nerve cells) builds up in your body. Symptoms of serotonin syndrome can include anxiety, shakiness, fever, diarrhea, fast heartbeat, and seizures.

If you experience any symptoms of serotonin syndrome, tell your doctor right away. They may recommend that you stop treatment with any supplement that may cause serotonin syndrome until your symptoms are treated.

Call 911 if your symptoms feel life-threatening or if you think you’re having a medical emergency.

Effexor XR and lab tests

Effexor XR can cause false-positive results for certain drug tests, such as tests for phencyclidine (PCP) or amphetamine/methamphetamine. This means that your drug test can show a positive result for PCP or amphetamines even though you did not use either of these drugs.

However, in case of a false-positive result, a second test can be done to rule out the use of PCP and amphetamines.

False-positive results can happen for several days after your last dose of Effexor XR. If you take Effexor XR and need to take a drug test, be sure to tell the test administrator about all medications you take. They will use this information when interpreting your test results.

Here are answers to some frequently asked questions about Effexor XR.

Is the immediate-release form of Effexor available?

No, the immediate-release form of brand-name Effexor is no longer on the market. (An immediate-release form of a drug releases the drug into your system as soon as your body absorbs it.) However, a generic form of immediate-release venlafaxine (the active drug in Effexor XR) is available.

If you’re interested in taking an immediate release form of venlafaxine, talk with your doctor.

Is Effexor XR a stimulant?

No, Effexor XR isn’t a stimulant. (Stimulants speed up the level of activity in your body’s systems, including your brain, to help make you more alert.) However, it does have several side effects that may make it seem like a stimulant to some people.

For example, some people have insomnia (trouble sleeping), headache, increased blood pressure, and loss of appetite while taking Effexor XR. (See the “Effexor XR side effects” section above for more details.)

If you’re concerned about whether Effexor XR is causing stimulant-like side effects for you, talk with your doctor. They can recommend ways to relieve these side effects.

If I stop taking Effexor XR, do I need to taper off of the drug?

Probably. A taper, or gradual decrease of your dose, is recommended when stopping Effexor XR. This is because stopping Effexor XR suddenly can cause side effects. Some of these side effects include feeling agitated, lack of energy, flu-like symptoms, trouble sleeping, and others.

If you and your doctor decide that stopping Effexor XR is right for you, they will likely recommend a gradual decrease of 75 mg per week.

For example, if you were taking 150 mg of Effexor XR per day, then your doctor may recommend that you decrease your dose to 75 mg per day for at least a week. After that week, they may recommend that you stop taking Effexor XR. However, each person’s taper will be different.

If you want to stop taking Effexor XR, talk with your doctor. They can discuss with you the safest way to do it. Don’t stop taking Effexor XR unless your doctor recommends that you do so.

Can I switch to Effexor XR if I’m using a short-acting form of venlafaxine?

You may be able to switch from a short-acting form of venlafaxine to Effexor XR if your doctor recommends that you do. (A short-acting form of a drug releases the active ingredient quickly for a faster effect. An extended-release form of a drug, such as the drug in Effexor XR, is released slowly for a more lasting effect.)

The short-acting form of venlafaxine comes as a tablet. If your doctor advises you to switch to Effexor XR, they may recommend a different dosage than you were taking of the short-acting form of venlafaxine. Don’t switch to the short-acting form without your doctor’s guidance.

It’s not known if it’s safe for pregnant women to use Effexor XR. There haven’t been any studies in humans to test its safety during pregnancy. Animal studies did show harm to the fetus when the mother received Effexor XR. However, animal studies don’t always predict what will happen in humans.

There have been reports of complications in newborns who were born to mothers who took Effexor XR. These symptoms were most commonly seen in newborns who were exposed to Effexor XR during the third trimester (the last few months before birth). The complications are generally considered withdrawal symptoms because the baby is no longer receiving Effexor XR after birth.

Complications and withdrawal symptoms included the need for tube feeding or breathing support, and an extended stay in the hospital. Other problems included constant crying, poor feeding, tense or shaky muscles, and vomiting.

These complications and symptoms can be treated by healthcare professionals. They typically go away within a few days or weeks.

Talk with your doctor if you are pregnant or considering becoming pregnant and want to take an antidepressant. They can discuss the safest options with you.

It’s not known if Effexor XR is safe to take during pregnancy. If you’re sexually active and you or your partner can become pregnant, talk with your doctor about your birth control needs while using Effexor XR.

Effexor XR does pass into human breast milk. This could cause side effects in nursing children, including unusual sleepiness and trouble gaining weight.

If you’re considering taking Effexor XR while breastfeeding, talk with your doctor about the risks and benefits.

Effexor XR contains the active drug venlafaxine. It’s the extended-release form of the drug. (An extended-release form of a drug slowly releases the active ingredient over a prolonged period of time.)

Effexor XR belongs to a class of drugs called serotonin-norepinephrine reuptake inhibitors (SNRIs). Drugs in the SNRI class treat depression and other related conditions by affecting the activity of serotonin and norepinephrine. These are two neurotransmitters (chemical messengers) that play a role in regulating your mood.

An imbalance of serotonin and norepinephrine levels can lead to conditions like depression, anxiety, and panic disorder.

Effexor XR and other SNRIs don’t allow serotonin and norepinephrine to be reabsorbed into nervous system cells in the brain. This allows the two neurotransmitters to stay active longer, which helps balance communication between nervous system cells in your brain.

Restoring the balance of serotonin and norepinephrine is thought to improve symptoms of depression, anxiety, and panic disorder.

How long does it take to work?

It may take several weeks before you begin to see your symptoms improve. This is because it takes time for the neurotransmitter levels in your brain to become stable. Talk with your doctor about how long you should wait to know whether or not Effexor XR is working for you.

As with all medications, the cost of Effexor XR can vary.

The actual price you’ll pay depends on your insurance plan, your location, and the pharmacy you use.

Your insurance company may require you to get prior authorization before they approve coverage for Effexor XR. This means that your doctor will need to send a request to your insurance company asking them to cover the drug. The insurance company will review the request and let you and your doctor know if your plan will cover Effexor XR.

If you’re not sure if you’ll need to get prior authorization for Effexor XR, contact your insurance company.

Financial and insurance assistance

If you need financial support to pay for Effexor XR, or if you need help understanding your insurance coverage, help is available.

Pfizer, Inc., the manufacturer of Effexor XR, offers a copay savings program, which may help lower the cost of Effexor XR. For more information and to find out if you’re eligible for support, call 855-436-4357 or visit the program website.

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

When to take

Effexor XR is taken once a day. You can take it in the morning or evening, but try to take it at the same time each day.

To help make sure you don’t miss a dose, try setting a reminder on your phone. A medication timer may be useful, too.

Taking Effexor XR with food

Effexor XR should be taken with food.

Can Effexor XR be crushed, split, or chewed?

No, Effexor XR should not be crushed, split, or chewed.

However, if you have trouble swallowing Effexor XR capsules, you can open the capsule and sprinkle the contents onto applesauce. You can mix it together or leave the contents on top. Be sure to empty the entire contents of the capsule.

Swallow the applesauce with Effexor XR contents without chewing. Drink a full glass of water after you swallow the applesauce. This will help make sure that you get your full dose of Effexor XR.

This drug comes with several warnings.

FDA warning: Increased risk of suicidal thoughts and behavior in young people

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.

Effexor XR has been linked to an increased risk of suicidal thoughts and behavior in children and young adults who are 24 years old and younger. This increased risk has been found for all antidepressants, not just Effexor XR.

Caregivers of young people who take Effexor XR should closely watch for signs of worsening depression and suicidal thoughts and behavior. Effexor XR is not approved for use in children.

Other precautions

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

  • Bipolar disorder or mania. Effexor XR should not be used to treat bipolar disorder, including manic episodes, because it can worsen these conditions. Before starting Effexor XR, your doctor will screen you for risk of bipolar disorder. If you have a family history of bipolar disorder or are unsure if you have bipolar disorder, talk with your doctor. They will determine if Effexor XR is safe for you.
  • Uncontrolled high blood pressure. Effexor XR can cause an increase in blood pressure. If you have high blood pressure that is not controlled with treatment or lifestyle changes, you shouldn’t take Effexor XR. Your doctor will likely recommend that your high blood pressure becomes controlled (at a healthy level) before starting Effexor XR.

When you get Effexor XR 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 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.
