Dapsone topical is used to treat acne in children, teenagers, and adults. Dapsone is in a class of medications called sulfone antibiotics. It works by slowing or stopping the growth of bacteria and to decrease inflammation.
Dapsone comes as a gel to apply to the skin. It is usually applied once (7.5% gel) or twice (5% gel) daily. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Apply dapsone exactly as directed. Do not apply more or less of it or apply it more often than prescribed by your doctor. Applying more dapsone or applying dapsone more often than recommended will not speed up or improve results, but it may irritate your skin.
It may take up to 12 weeks before you feel the full benefit of dapsone gel. If your acne does not improve after 12 weeks of treatment, call your doctor.
Be careful not to get dapsone gel in your eyes, nose, or mouth.

Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website ( Web Site) for more information if you do not have access to a take-back program.
It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. Web Site
