I have been taking dapsone for (rare) Linear IgA disease. I was increased to 100 mg 1Xday. Severe anemia set in. Hospitalized and given 2 blood transfusions. Its true that some people have a bad reaction and can develop anemia. Taken off medicine and skin blisters returned. Anemia went away! Am currently on 25 mg 1X day. Less effective, but helps some. I think DAPSONE is probably very effective to clear skin-- but can wreck hemoglobin, etc.
