Protopic, also known by its drug name Tacrolimus, is approved by the U.S. Food and Drug Administration (FDA) for the short-term treatment of mild to moderate atopic dermatitis. Protopic is prescribed off-label to treat vitiligo in children, and on sensitive areas such as face, eyelids, genitals, or breasts.1 Protopic may be used in combination with phototherapy for vitiligo.1
Protopic is an immunomodulator, or drug that modifies the immune system. More specifically, Protopic is a topical calcineurin inhibitor. It is believed that Protopic works by suppressing immune system activity.
How do I take it?
Protopic comes in ointment form. Applied topically to affected areas twice daily, the drug is approved for short-term (weeks) or intermittent long-term use.2
