Drug Uses
Dapsone is used for treatment of leprosy. It may be used in combination with other medications. It is also used to treat dermatitis herpetiformis (extremely itchy groups of skin lesions, usually occurring on the elbows, knees, and scalp). It may also be used for other conditions as determined by your doctor.

How Taken
Use Dapsone as directed by your doctor. Take Dapsone on an empty stomach. If stomach upset occurs, you may take it with food to reduce stomach irritation. If you also take didanosine, do not take it within 2 hours before or after taking Dapsone. To clear up your infection completely, take Dapsone for the full course of treatment. Keep taking it even if you feel better in a few days. Dapsone works best if it is taken at the same time each day.

Missed Dose
If you miss a dose take it as soon as you remember. However if it is almost time for the next dose, skip the Missed Dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.
