What is Opzelura™ (ruxolitinib)?
Opzelura™ (ruxolitinib) is a topical JAK inhibitor drug approved to treat mild to moderate atopic dermatitis (the most common form of eczema) in people 12 years or older who are not immunocompromised and whose atopic dermatitis is not well controlled with other topical drugs, or when other topical drugs cannot be used.1-3
The approval makes Opzelura the first topical Janus kinase (JAK) inhibitor approved in the United States. Several oral JAK inhibitors are approved to treat other conditions, such as rheumatoid arthritis.1,2
The FDA granted priority review to Opzelura. The FDA can give priority review when a new drug seems promising and may greatly help a disease. Priority review means the FDA will decide whether to approve new drugs in 6 months. It is only for drugs that seem to work better or are safer than current treatments.1,2
What are the ingredients in Opzelura?
The active ingredient in Opzelura is ruxolitinib phosphate.1-3
How does Opzelura work?
Opzelura is a JAK inhibitor. JAK proteins aid in making immune cells that cause atopic dermatitis symptoms, such as redness, itching, and inflammation. JAK inhibitor drugs block JAK proteins, making inflammatory reactions less likely.1,2
What are the possible side effects?
The most common side effects of Opzelura include:2
- Common cold/runny nose
- Ear infection
- Hair follicle inflammation
- Increased white blood cell count
Serious side effects
Opzelura has a boxed warning, the strictest warning from the U.S. Food and Drug Administration (FDA). It has this warning because JAK inhibitors for inflammatory conditions can cause serious problems, including:3
- Serious infections that can cause hospitalization or death, including tuberculosis
- A higher rate of death, including sudden cardiovascular death
- Lymphoma and other cancers
- Major heart effects including heart attack, stroke, and death
- Clotting events, including clots in the lungs and legs, that can cause death
These are not all the possible side effects of Opzelura. Talk to your doctor about what to expect when using Opzelura. You also should call your doctor if you have any changes that concern you when using Opzelura.
