2. Administration route and dosage

1.Routes of administration: Clofazimine is usually administered orally, in the form of capsules or tablets. In addition, topical administration may sometimes be used on a case-by-case basis, such as clofazimine suspension applied to the skin surface.

2.Dosage: The dosage of clofazimine is usually based on the patient's age, weight, severity of illness, and concomitant use of other medications. Generally speaking, the standard dose for adults is 50-100 mg per day, administered orally once a day, with the maximum dose not exceeding 300 mg.
