I did a lot of research on dapsone ...as it is unusual to prescribe dapsone for acne it is mainly used for leprosy . I spent the last two hours studying it ... and my study concludes that its not as usefull as the tane !!
It has serious side effects. Also it is used to treat only acne fulminans which is a severe form of nodular cystic acne which comes along with musculoskeletal pain .
So all in all I have decided to not take the dapsone at all and continue with the tane .
