You may have diarrhea while you’re taking Otezla. In fact, the most common side effect of Otezla is diarrhea. With diarrhea, you may have more frequent, loose, or watery stools.

Some people may have severe diarrhea while taking Otezla. With severe diarrhea, you can have:

If you have severe diarrhea with Otezla, call your doctor. They may lower your dosage of the drug. If needed, your doctor may even have you stop taking Otezla. Don’t stop taking the medication without first talking with your doctor.

Sometimes, for severe diarrhea, you may need intravenous (IV) fluids and electrolytes. (You’ll get IV fluids as an injection into your vein that’s given over a period of time.)

Symptoms of a mild allergic reaction can include:

Your doctor may prescribe Otezla for you if you have certain conditions. This drug is used in adults to treat:

  • Plaque psoriasis. With plaque psoriasis, you have patches on your skin that are discolored. Sometimes, they can look scaly and white. This condition is an inflammatory skin disease that’s caused by your immune system attacking your own cells. For this use, Otezla is prescribed for people who could have used systemic therapy (which affects your whole body) or light therapy.
  • Psoriatic arthritis. With psoriatic arthritis, you have arthritis, which causes achy, stiff joints. And you have psoriasis, which causes the skin issues described just above. This condition is also caused by your immune system attacking certain cells in your body.
  • Mouth sores in people with Behçet’s disease. With Behçet’s disease, you can have several symptoms, such as problems with your eyes and skin, and joint pain. Mouth sores are one of the earliest symptoms of the condition. Otezla can be used to treat these mouth sores. Behçet’s disease is also caused by your immune system attacking certain cells in your body.

Otezla treats these conditions by helping to lower the activity of your immune system.

Below, you’ll find answers to some commonly asked questions about Otezla.

Is Otezla an immunosuppressant?

Yes, Otezla is called an immunosuppressant drug. This means it suppresses (reduces) your immune system’s activity.

This immune system suppression is how Otezla works to treat certain conditions. It reduces inflammation caused by your immune system and eases symptoms of the conditions.

If you have more questions about how Otezla works, talk with your doctor or pharmacist.

Is Otezla a biologic drug?

No, Otezla isn’t a biologic drug. Biologics are drugs made from living cells. They work against a specific part of your immune system.

Certain nonbiologic drugs, including Otezla, also act on your immune system. Nonbiologic drugs are made from chemicals rather than from living cells.

If you have more questions about how Otezla works, talk with your doctor or pharmacist.

How does Otezla compare to Humira?

Otezla and Humira are both used to treat plaque psoriasis and psoriatic arthritis. They each also have other uses.

Unlike Otezla, Humira is a biologic drug. This means Humira is made from parts of living cells. Otezla, on the other hand, is made from chemicals.

Otezla comes as tablets that you’ll take by mouth, typically twice each day. But you’ll take Humira as an injection under your skin. Usually, it’s taken once every 2 weeks, after the first week of treatment.

If you have more questions about the differences between Otezla and Humira, talk with your doctor.

Does stopping Otezla cause withdrawal?

If you stop taking Otezla, you likely won’t have withdrawal symptoms. But, the symptoms you were taking Otezla to treat may start coming back.

Talk with your doctor before stopping Otezla. They can tell you what to expect if you quit taking this medication.

In some cases, your doctor may recommend that you take a drug other than Otezla, depending on the condition you’re treating.

Alternatives for plaque psoriasis, psoriatic arthritis, or mouth ulcers caused by Behçet’s disease may include biologics and nonbiologics. Biologics are drugs made from parts of living cells. Nonbiologics are drugs made from chemicals.

Some of the drugs listed below are used off-label for these conditions. With off-label use, a drug that’s approved for certain conditions is used for another condition.

Alternatives for plaque psoriasis or psoriatic arthritis

Alternative drugs for plaque psoriasis or psoriatic arthritis include the following:

Can turmeric help relieve my psoriatic arthritis?



Turmeric is commonly used in cooking, but it’s also available as a nutritional supplement. The active ingredient in turmeric is called curcumin. This ingredient has been shown to help reduce inflammation.

Studies have shown that turmeric may be able to help relieve symptoms of pain in some conditions. These symptoms may include joint pain that’s associated with inflammation from certain kinds of arthritis. But, the studies were small, and their results weren’t always consistent. So, more studies are needed to fully understand how turmeric works to relieve joint pain.

Always talk with your doctor before using any natural or alternative therapies for your condition. This is especially important to do if you’re taking any medications. And even if a natural remedy helps improve your symptoms, don’t stop taking any prescribed medications without your doctor’s recommendation.
