Atopic dermatitis treatment: Crisaborole (Eucrisa®) ointment


Crisaborole ointment

Crisaborole ointment is a newer treatment for atopic dermatitis (AD), which offers an alternative to treating AD with corticosteroids that you apply to the skin, pimecrolimus cream, or tacrolimus ointment.

Why do dermatologists prescribe this medication to treat atopic dermatitis? This is a newer treatment for people who have mild to moderate atopic dermatitis (AD). Studies show that crisaborole ointment can effectively treat:

  • Inflammation (redness, swelling, heat)

  • Itch (shown to relieve the itch in a few days)

  • Rash

FDA Approval

In 2016, the U.S. Food and Drug Administration (FDA) approved crisaborole ointment to treat people who:

  • Have mild to moderate AD

  • Are 2 years of age or older

Safety and effectiveness

In the clinical trials that led the FDA to approve crisaborole, the researchers enrolled 1,522 patients who had mild to moderate AD. Their ages ranged from 2 to 79 years old.

To test the safety and effectiveness of this medication, some patients received crisaborole ointment. The other patients were given a moisturizing ointment that looked like crisaborole, but the ointment contained no medication.

In these clinical trials:

  • About one-third of the participants treated with the crisaborole ointment had clear or almost clear skin after applying the ointment twice a day for 28 days.

  • Crisaborole was found to relieve the itch in more patients than did the moisturizer. On day 2 of the study, 34% of patients using crisaborole had stopped itching vs. 27% using the moisturizer. By the end of the study, 57% of the patients treated with crisaborole no longer had itchy skin vs. 40% using the moisturizer.

  • The most common side effect of crisaborole is burning or stinging where you apply it. This usually happens immediately after applying crisaborole.

  • Less than 2% of patients experienced side effects that caused them to stop using the medication. Just as many patients who received the moisturizer stopped using it due to side effects.

In a longer study that ran 48 weeks, researchers found that few patients developed side effects.

More research is needed to learn the long-term effects.

How to use crisaborole

Use as directed

You apply a thin layer of crisaborole ointment to the skin as directed. It’s usually applied twice a day.

Best results are obtained when you use this medication along with:

  • Bathing

  • Eczema friendly moisturizer

  • Trigger management

Apply after bathing: Dermatologists recommend applying crisaborole immediately after getting out of the water. After applying crisaborole, wait 15 minutes before applying your moisturizer.

Wash your hands after applying crisaborole: There is one exception to this advice. If you are treating your own hands with this medication, do not wash your hands after applying it.

If you are not treating your hands or you are applying crisaborole to someone else, wash your hands immediately after you apply this medication.

Possible side effects

The most common side effects reported during the clinical trials were:

  • Burning or stinging when applied to the skin

  • Worsening atopic dermatitis

  • Skin infection

Fewer than 4% of patients experienced any one of these side effects.

Tip: If crisaborole stings when you apply it, keep this medication in the refrigerator. Applying it cold can prevent that stinging sensation.

When should I call my dermatologist?

Call your dermatologist, if you apply crisaborole and notice any of the following:

  • Eczema worsens

  • Skin infection develops

  • No improvement after applying for 4 weeks
