Ok so I'm really confused. I've heard a lot about this 100mg/kg theory, and that your body weight needs to be addressed in order to start a specific dosage/length of time etc. My dermatologist never mentioned this to me, but it seems to be rather important, as I have noticed that a lot on people on here seem to swear by this rule.
I am taking a second round of Roaccutane and I seriously do not want to be doing this again; I want my acne gone. However, my dermatologist only suggested a 4 month treatment, with 40mg at the highest. According to the 100mg/kg theory, this is not enough in total. It is only 4,440mg in total, but I have worked out that I'll need 5,500kg at least, because I weigh 55kg. Should I go for an extra month (5 months) to ensure this or listen to my derm?
