Reviewed by: HU Medical Review Board | Reviewed February 2022 | Last updated: February 2022

Eucrisa® is a topical treatment for mild to moderate atopic dermatitis in individuals 3 months of age and older.4

What are the ingredients in Eucrisa?

The active ingredient in Eucrisa is crisaborole (2%).1

How does Eucrisa work?

While the exact mechanism of action of Eucrisa in atopic dermatitis is not well understood, topical PDE4 inhibitors increase the levels of a chemical messenger called cyclic adenosine monophosphate (cAMP).1,2 The increase of cAMP in your body then suppresses the release of proteins called cytokines that cause inflammation which can lead to atopic dermatitis.5,6

In people with atopic dermatitis, the immune response is dysfunctional, resulting in an increased level of inflammation in the skin. By increasing cAMP levels and interrupting the immune response of inflammation, topical PDE4 inhibitors like Eucrisa can reduce the symptoms of atopic dermatitis like redness, oozing, crusting, and papules (bumps).1

What are the possible side effects of Eucrisa?

The most common side effect experienced by people using Eucrisa in clinical trials was pain at the application site, such as burning or stinging.

Rarely, hypersensitivity reactions have occurred in people using Eucrisa, including contact urticaria. Contact urticaria is an immediate, localized hypersensitivity reaction that occurs on the skin and usually clears within a few hours. If a hypersensitivity reaction occurs, with symptoms including severe itching, redness, and swelling at the application site or at a distant site, the use of Eucrisa should be discontinued immediately. Additional medical attention may be needed.1,3

These are not all the possible side effects of Eucrisa. Patients should talk to their doctor about what to expect with treatment with Eucrisa.
