Tacrolimus ointment is not usually applied for a long period of time, and patients are advised to use it externally for a short period of time or intermittently for a long period of time under the supervision of a doctor. When applying the medication, take an appropriate amount of the ointment and apply it thinly on the affected area and rub it well so that it covers the affected area completely. Tacrolimus Ointment is indicated for moderate to severe atopic dermatitis that has not responded adequately to conventional therapies and for which the use of conventional therapies is contraindicated. Because the safety of long-term application of tacrolimus ointment is not known, it should not generally be used continuously topically for long periods of time. Short-term application or intermittent repeated topical application is recommended. The medication needs to be applied by cleansing the area, keeping the affected area dry, applying a thin layer to the local skin and rubbing it in gently until the affected area is completely covered. Burning sensation, itching, skin erythema, skin infection and other adverse reactions may occur after the use of the drug, tacrolimus ointment should be prohibited for those who are allergic to tacrolimus ointment. If you want to use tacrolimus ointment externally, it is recommended to go to a regular hospital to consult a doctor and use the medication under the doctor’s guidance, and not to use the medication without authorization.
