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:
Allergies--Tell your doctor if you have ever had any unusual or allergic reaction to dapsone or sulfonamides. Also tell your health care professional if you are allergic to any other substances, such as foods, preservatives, or dyes.
Pregnancy--Studies have not been done in humans or animals. However, reports on the use of dapsone in humans have not shown that this medicine causes birth defects or other problems.
Breast-feeding--Dapsone passes into the breast milk. Dapsone may cause blood problems in nursing babies with glucose-6-phosphate dehydrogenase (G6PD) deficiency. Breast-feeding may need to be stopped because of the risks to the baby.
Children--Although there is no specific information comparing use of dapsone in children with use in other age groups, this medicine is not expected to cause different side effects or problems in children than it does in adults.
Older 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.
