You really need to ask your doctor this because there's no sure
yes or no. This is what they say on Drugs.com (a very good
site):
If you become pregnant, contact your doctor. You will need to
discuss the benefits and risks of using Dapsone while you are
pregnant. Dapsone is found in breast milk. Do not breast-feed while
taking Dapsone.
Dapsone has been assigned to pregnancy category C. There are no
animal data or controlled data in human pregnancies. Experience
with dapsone during all trimesters of human pregnancy has not
indicated an increased risk of fetal abnormalities. Dapsone should
only be given during pregnancy when benefit outweighs risk.
Dapsone is excreted into human milk. Hemolytic reactions have
been reported in neonates. Due to the potential for serious adverse
effects in a nursing infant, a decision should be made to
discontinue nursing or discontinue the drug, taking into
consideration the importance of the drug to the mother.
