Dapsone , a sulfone, belongs to the family of medicines called anti-infectives.
Dapsone is used to treat leprosy (Hansen's disease) and to help control dermatitis herpetiformis, a skin problem. When it is used to treat leprosy, dapsone may be given with one or more other medicines. Dapsone may also be used for other conditions as determined by your doctor.
Dapsone is available only with your doctor's prescription.
Once a medicine has been approved for marketing for a certain use, experience may show that it is also useful for other medical problems. Although these uses are not specifically included in product labeling, dapsone is used in certain patients with the following medical conditions:

In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For dapsone, the following should be considered:
Tell your doctor if you have ever had any unusual or allergic reaction to dapsone or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Although there is no specific information comparing use of dapsone in children with use in other age groups, dapsone is not expected to cause different side effects or problems in children than it does in adults.
Many medicines have not been studied specifically in older people. Therefore, it may not be known whether they work exactly the same way they do in younger adults or if they cause different side effects or problems in older people. There is no specific information comparing use of dapsone in the elderly with use in other age groups.

The dose of dapsone will be different for different patients. Follow your doctor's orders or the directions on the label. The following information includes only the average doses of dapsone. If your dose is different, do not change it unless your doctor tells you to do so.
The amount of medicine that you take depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are using the medicine.
If you miss a dose of dapsone, take it as soon as possible. However, if it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not double doses.
You may skip a missed dose if it does not make your symptoms come back or get worse. If your symptoms do come back or get worse, take the missed dose as soon as possible.
Store the medicine in a closed container at room temperature, away from heat, moisture, and direct light. Keep from freezing.
Keep out of the reach of children.
Do not keep outdated medicine or medicine no longer needed.

If your symptoms do not improve within 2 to 3 months (for leprosy), or within a few days (for dermatitis herpetiformis), or if they become worse, check with your doctor.
