Tacrolimus ointment is primarily used to treat the symptoms of eczema (atopic dermatitis), a chronic skin condition characterized by dryness, itching, and sometimes red, scaly rashes in both adults and children 2 years of age and older who either cannot use other medications or have not responded adequately to them[1][2][3][5]. Tacrolimus works by suppressing the immune system’s response locally on the skin, thus reducing inflammation and the urge to itch[1][2][3].
This ointment is generally used as a second-line therapy for short-term and non-continuous treatment of moderate-to-severe atopic dermatitis when other topical treatments are not advisable or have failed[5]. It is available in two strengths—0.03% and 0.1%—with the lower strength typically recommended for pediatric patients aged 2 to 15 years[3][5].
Tacrolimus ointment is not a steroid; it belongs to a class of medicines called topical calcineurin inhibitors, which act differently from corticosteroids by specifically blocking a protein (calcineurin) that activates the immune system to cause skin inflammation[1][2].
In some cases, tacrolimus ointment may be prescribed off-label for other inflammatory skin disorders, such as psoriasis or vitiligo, although its primary approved use is for atopic dermatitis[4][7].
