Tacrolimus is a calcineurin inhibitor, while triamcinolone is a corticosteroid. Tacrolimus is specifically FDA-approved for moderate-to-severe eczema in adults and children ages 2 and older, whereas triamcinolone is used for a number of inflammatory skin conditions, including eczema, psoriasis, and skin allergies. Tacrolimus is an ointment that is applied twice daily, while triamcinolone comes in multiple forms, such as creams, ointments, lotions, and sprays, and is applied 2 to 4 times daily depending on the formulation. Common tacrolimus side effects include burning, itching, and flu-like symptoms. Triamcinolone rarely causes side effects, but can cause include burning, itching, and dryness. Tacrolimus may increase your risk of skin infections and sensitivity to sunlight, while triamcinolone can cause skin thinning and other skin changes if used excessively or for long periods of time.
