Dapsone

Leprosy: The recommended adult dose of dapsone when used for leprosy is 100 mg daily. For children, the dose should be adjusted according to body weight (1 mg to 2 mg per kilogram of body weight daily). Dapsone is used in combination with other medications.

Dermatitis herpetiformis: To treat dermatitis herpetiformis, the usual starting dose is 50 mg once daily, to be increased until an effective dose is reached. In some cases, up to 300 mg daily may be required.

Actinomycotic mycetoma: The recommended dose of dapsone is 100 mg taken 2 times a day. Treatment should be continued until the infection clears and then for several months later.

Many things can affect the dose of a medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are taking the medication without consulting your doctor.

The medication needs to be taken for several months after the symptoms have disappeared to prevent the condition from returning. It is important to take dapsone as directed for as long as it has been prescribed, even if you are feeling better.
