Patient Education

Tacrolimus Topical


Tacrolimus ointment is used to treat the symptoms of eczema (atopic dermatitis; a skin disease that causes the skin to be dry and itchy and to sometimes develop red, scaly rashes) in patients who cannot use other medications for their condition or whose eczema has not responded to another medication. Tacrolimus is in a class of medications called topical calcineurin inhibitors. It works by stopping the immune system from producing substances that may cause eczema.
