Opzelura (Ruxolitinib) – Topical

What Is Opzelura?

Opzelura (ruxolitinib) is a prescription-only topical cream approved by the Food and Drug Administration (FDA) to treat mild to moderate atopic dermatitis and nonsegmental vitiligo. 

Atopic dermatitis is the most common form of eczema and affects approximately 30% of the U.S. population. 

Opzelura is in a class of medications known as Janus kinase (JAK) inhibitors. JAK enzymes cause and promote types of inflammation in the body. Opzelura works by interfering with these enzymes, preventing inflammation that would otherwise lead to redness and itching of the skin. This same inflammation can cause vitiligo in some people.

Opzelura carries a boxed warning on its label due to the increased risk of serious infections, lymphoma or other cancers, sudden heart attack or stroke, and blood clots. A boxed warning (or black box warning) is the FDA's highest safety-related warning for a medication. Your healthcare provider should discuss any potential risks before using this medication.

Opzelura is a topical treatment, meaning it is applied to the skin. It is available as a cream.

What Is Opzelura Used For?

The FDA approved Opzelura to treat:

  • Mild to moderate atopic dermatitis (AD) in adults and children over the age of 12 who have no problems with their immune system and whose symptoms are not controlled by other topical therapies or if other treatments are not advisable
  • Nonsegmental vitiligo in adults and children over 12

AD is a skin disorder that causes red, itchy, inflamed skin that can weep clear fluid when scratched.  Nonsegmental vitiligo is the most common type of vitiligo. It is characterized by a symmetrical loss of pigmentation on the skin. This pigment loss is more readily visible on darker skin tones, as the loss of pigment and smooth, whitish patches stand out more.

How to Use Opzelura

How you use Opzelura will depend on whether you are treating AD or vitiligo.

Atopic Dermatitis

When using Opzelura for AD, apply a thin layer to affected areas twice a day. It should cover no more than 20% of your body's surface area. Stop using Opzelura when the itch, redness, and rash resolve. If there is no improvement within eight weeks, contact your healthcare provider.


When using Opzelura for vitiligo, apply a thin layer to the affected areas twice a day. This area should cover no more than 10% of your body. It may take up to 24 weeks of treatment or longer to see a meaningful response. If there is no improvement after 24 weeks of treatment, contact your healthcare provider.

Regardless of why you are using Opzelura, washing your hands before and after applying the cream is important unless your hands are affected by the condition. If your healthcare provider also recommends a moisturizer, you should use it after applying Opzelura.


Store Opzelura cream at room temperature (68–77 degrees Fahrenheit) away from moisture and light. Keep it out of the reach of children and pets.

How Long Does Opzelura Take to Work?

If you are using Opzelura to treat AD, you should notice improvement within eight weeks. You may experience relief of itching within the first 12 hours.  If you are using it for vitiligo, it may take up to six months to show marked symptom improvement.

What Are the Side Effects of Opzelura?

This is not a complete list of side effects and others may occur. A healthcare provider can advise you on side effects. If you experience other effects, contact your pharmacist or a healthcare provider. You may report side effects to the FDA at www.fda.gov/medwatch or 800-FDA-1088.

Common Side Effects

Common side effects associated with Opzelura include:

  • Pain or swelling in your nose or throat
  • Hives
  • Ear infection
  • Diarrhea
  • Runny nose
  • Swelling of the tonsils

Severe Side Effects

Call your healthcare provider immediately if you have serious side effects. Call 911 if your symptoms feel life-threatening or if you think you’re having a medical emergency. Serious side effects can include the following:

  • Serious cardiovascular event risk, such as stroke, heart attack, or a blood clot in lungs, arteries, or veins
  • Low blood cell counts, such as anemia (low red blood cells), neutropenia (low white blood cells), and thrombocytopenia (low platelets)

What Are Reasons I Shouldn’t Use Opzelura?

Do not use Opzelura if you:

  • Currently have an infection
  • Have ever had a heart attack, stroke, or a blood clot
  • Are under the age of 12

There is no information available about Opzelura's safety in pregnancy or while breastfeeding. If you are pregnant or breastfeeding, it is best to speak with your healthcare provider to determine if Opzelura would be a safe treatment option.

What Other Medications Interact With Opzelura?

Since it is a topically applied cream, Opzelura has few drug interactions.

Opzelura may interact with Vonjo (pacritinib), which is an oral capsule used to treat myelofibrosis (a disease that causes scarring of the bone marrow, leading to abnormal blood cell counts and other serious complications). Like Opzelura, Vonjo is a JAK inhibitor. Using these drugs together can increase the chance of experiencing severe side effects.  

It is not recommended to use Opzelura with other JAK inhibitors, such as Jakafi (ruxolitinib), which contains the same active ingredient as Opzelura; potent immunosuppressants, such as Azasan (azathioprine) or Gengraf (cyclosporine); or certain biologics, such as Enbrel (etanercept) or Humira (adalimumab).

If your healthcare provider recommends using a moisturizer with Opzelura, it is best to apply Opzelura first before applying the moisturizer.

What Medications Are Similar?

Opzelura belongs to a family of drugs known as JAK inhibitors. It is the first topical drug in its class, but there are oral forms of JAK inhibitors, such as:

  • Jakafi (ruxolitinib), which has same active ingredient as Opzelura, but Jakafi is a capsule dosage form and treats different conditions
  • Xeljanz (tofacitinib), which treats various forms of arthritis
  • Olumiant (baricitinib), which treats rheumatoid arthritis
  • Rinvoq (upadacitinib), which treats AD and rheumatoid arthritis

This is a list of drugs in the same family of drugs as Opzelura. It is not a list of drugs recommended to take with Opzelura. In fact, you should not take these drugs together. Discuss any questions with your pharmacist or a healthcare provider.

Frequently Asked Questions

  • Is Opzelura a steroid cream?

    No, Opzelura is not a steroid cream. It has different properties and works in different ways than steroid creams. Unlike many steroid creams, Opzelura can be used on the face, as long as you avoid contact with the eyes and mouth. Opzelura does not have the same side effects as steroids, but it does have a different set of side effects that can be just as serious.

  • How is Opzelura supplied?

    Opzelura is supplied in 60-gram tubes. You should not use more than one tube per week if using the maximum dosage. This is the only size and packaging in which Opzelura is currently sold.

  • How much does Opzelura cost?

    One 60-gram tube of Opzelura retails at a list price of $1,950.00. However, this price may not reflect what you will pay. Insurance can significantly decrease this amount. If Opzelura is unaffordable, the manufacturer, Incyte Dermatology, may have a patient assistance program that offers the medication at a deep discount.

  • Since ruxolitinib is the active ingredient in both Opzelura and Jakafi, can I use Jakafi instead if I would rather take a pill?

    No. Although both Opzelura and Jakafi are the same drug, they are used to treat very different diseases. While Opzelura treats skin conditions such as atopic dermatitis and vitiligo, Jakafi treats conditions such as myelofibrosis (a rare bone marrow disease), polycythemia vera (a disease in which your body produces too many blood cells, which increases the risk of blood clots in the body), and graft-versus-host disease (a condition in which the body attacks donor tissue after a transplant). Opzelura and Jakafi cannot be used interchangeably to treat any disease.

How Can I Stay Healthy While Taking Opzelura?

It is important to ensure that all of your questions and concerns are addressed with your healthcare provider before and during treatment with Opzelura. If at any time you feel that something is not right or you believe you are developing an infection, contact your healthcare provider immediately. 

Washing your hands before and after applying Opzelura can help ensure the medication only affects the desired areas (unless your hands are also affected by your disease). Use the medication regularly to get the most out of your treatment.

While using Opzelura, check with your healthcare provider or pharmacist about drug-to-drug or supplement-to-drug interactions before starting any new medications, vitamins, or herbal supplements.
