Does Otezla cause any long-term side effects?

It’s not common for Otezla to cause long-term side effects. However, long-term side effects from Otezla are possible. For example, weight loss can be a long-term side effect of taking Otezla in some people. (For more information about this side effect, see the “Side effect specifics” section below.)

If you have concerns about long-term side effects that can occur from taking Otezla, talk with your doctor or pharmacist.

Can I have withdrawal symptoms from stopping Otezla?

No, you should not experience withdrawal side effects from stopping Otezla. (With withdrawal, you experience uncomfortable symptoms after stopping a drug that your body has become dependent on.)

However, stopping Otezla may worsen the symptoms of the condition you’re taking it to treat. For example, if you take Otezla to treat psoriatic arthritis (PsA) and you stop treatment, your symptoms of PsA may come back.

If you’d like to stop treatment with Otezla, talk with your doctor. They can advise whether you should expect any side effects after stopping the drug.

Is hair loss a side effect of Otezla?

No, you should not experience hair loss from Otezla treatment. Hair loss wasn’t a side effect that people taking the drug reported in clinical trials. Otezla isn’t known to cause hair growth either.

However, it’s possible for plaque psoriasis to cause hair loss if the condition affects your scalp. (Otezla is used to treat plaque psoriasis. For more details about Otezla’s uses, see this article.)

If you notice hair loss during your treatment with Otezla, talk with your doctor. They can help determine what may be causing your hair loss and the best way to manage it. If you have additional concerns about Otezla and hair loss, talk with your doctor or pharmacist.

Does Otezla cause sun sensitivity?

No, sun sensitivity was not reported in clinical trials of Otezla. So you should not experience sun sensitivity during your treatment.

Other drugs that may be used to treat your condition may cause sun sensitivity. For example, methotrexate (Trexall) may cause sun sensitivity as a side effect. Similar to Otezla, methotrexate can be used to treat plaque psoriasis or PsA.

In some cases, sunlight may help treat plaque psoriasis in certain people.

If you have concerns about sun sensitivity during Otezla treatment, talk with your doctor or pharmacist.

Should I expect muscle pain with Otezla treatment?

No, muscle pain should not occur from taking Otezla. This was not a side effect that people taking this drug reported in clinical trials. However, back pain and joint pain* are side effects that people experienced during Otezla treatment.

If you experience pain during your treatment, talk with your doctor. They can help determine what type of pain you’re experiencing and what may be causing it. They may also be able to recommend treatment options for you.

Headache

Otezla may cause headache. This was one of the most common side effects that people reported in clinical trials of the drug. Different types of headaches were reported, including tension headache, sinus headache, or migraine headache.

Symptoms of a headache may include head pain or dizziness.

What you can do

If you’re experiencing headaches that are severe or bothersome during your treatment with Otezla, talk with your doctor. They may be able to recommend treatment options for your headaches. For example, they may recommend taking acetaminophen (Tylenol) to help relieve pain.

Nausea, vomiting, and diarrhea

Some people may experience digestive side effects such as nausea, vomiting, and diarrhea while taking Otezla. These were the most common side effects reported in clinical trials of the drug. For most people, these side effects were mild or temporary.

It’s possible for nausea, vomiting, or diarrhea to become severe during Otezla treatment. In most cases, severe symptoms occur during the first few weeks of treatment.

Severe nausea, vomiting, or diarrhea can lead to dehydration. This condition can become serious and may lead to other problems. These can include heart palpitations or kidney or liver damage. You may have an increased risk of developing dehydration if you:

  • are ages 65 years or older
  • have low blood pressure
  • take medications that can cause low blood pressure
  • take medications that increase the risk of dehydration

What you can do

If you develop nausea, vomiting, or diarrhea from taking Otezla, talk with your doctor. They can help determine whether your symptoms are severe and the best ways to manage them.

Sometimes, taking a medication with food may help decrease nausea. Otezla can be taken with or without food.* So your doctor may recommend taking the drug with a meal or snack.

Your doctor may monitor you for these side effects throughout your Otezla treatment. If you develop severe symptoms, they may recommend decreasing your dose of Otezla.† Or they may recommend pausing or stopping your treatment completely.

If you’re experiencing nausea, vomiting, or diarrhea during your treatment with Otezla, talk with your doctor about the best plan for you.

Weight loss

It’s possible for Otezla to cause weight loss. However, weight loss was not one of the most common side effects reported in clinical trials of Otezla.

Otezla can cause a decrease in appetite. This may lead to weight loss. Otezla can also cause digestive side effects, such as nausea, vomiting, or diarrhea. In some cases, these side effects can be severe and may lead to weight loss.

What you can do

Your doctor will recommend monitoring your weight while you’re taking Otezla. If you notice unexpected weight loss or a large decrease in your body weight, tell your doctor.

If your weight loss is due to digestive side effects or a decrease in appetite, your doctor may recommend treatment options for those side effects. This may help to manage your weight loss. However, in some cases, your doctor may recommend stopping treatment with Otezla. They may recommend taking a different medication for your condition instead.

Joint pain

Joint pain can occur from taking Otezla. Joint pain was only reported in clinical trials of people taking Otezla to treat mouth ulcers (sores) due to Behçet’s disease. This side effect wasn’t reported in clinical trials of people taking Otezla for psoriatic arthritis (PsA) or plaque psoriasis.

What you can do

If you experience joint pain during your treatment with Otezla, talk with your doctor. They can help determine whether Otezla may be causing your joint pain.

It’s important to note that people with PsA may experience joint pain from the condition itself. In this case, your doctor can help determine whether Otezla is working to treat your condition or whether it’s worsening your joint pain.

Your doctor can recommend ways to treat your joint pain from Otezla. In some cases, they may recommend an over-the-counter treatment option, such as acetaminophen (Tylenol).

Depression

Otezla can increase the risk of depression. In clinical trials, depression was not common. However, it can still occur.

Symptoms can include:

  • feeling sad or hopeless
  • changes in your appetite
  • insomnia or sleeping more often than usual
  • lack of interest in activities that you used to enjoy

In the drug’s clinical trials, some people developed suicidal thoughts as a symptom of severe depression. However, this was rare.

If you’ve ever had depression or other mood conditions, you may have an increased risk of new or worsening depression during Otezla treatment.

What you can do

It’s important for you and your caregivers to be aware of the above symptoms of depression during your Otezla treatment.

If you develop symptoms of new or worsening depression, tell your doctor right away. They can help determine the best treatment plan for you. In some cases, they may recommend treatment for your depression, such as talk therapy or medication. They may also recommend pausing or stopping Otezla treatment.

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 it’s safe to do so.

Allergic reaction

As with most drugs, Otezla can cause an allergic reaction in some people. Allergic reaction was not reported in clinical trials. However, severe allergic reactions have been reported in people taking Otezla since the drug has become available for use.

Symptoms can be mild or serious and can include:

  • skin rash
  • itching
  • flushing
  • swelling under your skin, typically in your eyelids, lips, hands, or feet
  • swelling of your mouth, tongue, or throat, which can make it hard to breathe

However, if your symptoms are serious and you think you’re having a medical emergency, immediately call 911 or your local emergency number.

Be sure to talk with your doctor about your health history before you take Otezla. This drug may not be the right treatment option for you if you have certain medical conditions or other factors that affect your health. These are known as drug-condition or drug-factor interactions. The conditions and factors to consider include:

Depression or mood problems. It’s possible for Otezla to cause changes in your mood, including depression or suicidal thoughts. If you already have depression or a mood problem, taking Otezla may make your condition worse. In this case, your doctor can help determine whether Otezla is a safe treatment option for you.

Kidney problems. Tell your doctor about any kidney problems that you have before taking Otezla. In some cases, your doctor may recommend that you take a lower dose of Otezla if you have a kidney problem. Your doctor can help determine the best dosage for you in this case. (To learn about Otezla’s dosage, see this article.)

Allergic reaction. If you’ve had an allergic reaction to Otezla or any of its ingredients, your doctor will likely not prescribe Otezla. Ask your doctor what other medications may be better options for you.

Alcohol with Otezla

There aren’t any known interactions between Otezla and alcohol. However, Otezla’s side effects may worsen if you drink alcohol.

For example, Otezla can cause nausea, vomiting, headache, and fatigue. Alcohol can also cause these side effects. So if you drink alcohol while taking Otezla, you may have an increased risk of these side effects occurring.

If you have questions about Otezla side effects with alcohol, talk with your doctor.

Pregnancy and breastfeeding while taking Otezla

It’s not known whether it’s safe to take Otezla during pregnancy or while breastfeeding.

Currently, there aren’t enough clinical trials to determine what effects Otezla may have on a fetus. However, animal trials showed an increased risk of pregnancy loss or congenital anomalies (commonly known as birth defects) in animals exposed to the drug during pregnancy. It’s important to note that animal trials don’t always indicate what may happen in humans.

In addition, it’s not known whether Otezla is safe to take while breastfeeding. At this time, it’s not known whether the drug passes into breast milk or what effects it may have on a child who is breastfed. In animal trials, the drug was shown to pass into breast milk. However, animal trials don’t always predict what happens in humans.

If you’re pregnant, planning to become pregnant, or breastfeeding, talk with your doctor before taking Otezla.

In most cases, side effects of Otezla are mild. However, serious side effects from Otezla are also possible.

If you’d like to learn more about Otezla, talk with your doctor or pharmacist. They can help answer any questions you have about side effects from taking the drug.
