Hello, I can understand your frustration. Acne is a chronic condition and can be effectively kept under ' control'. Isotretinoin is one of the wonder drug to treat acne. Your Dermatologist is the best person to decide ideal dose and time duration you need to take the medicine. You will need to undergo a couple of blood tests at regular intervals while on the medication and inform your when you decide to get married as you cant conceive while you are on this medicine. Along with this you need to focus on lifestyle changes like daily exercise, weight reduction ( if you are overweight) ,avoiding outside junk food, dairy products and consume lots of vegetables to counter PCOD- the main reason for your acne. Hope this helps. Regards, Dr Pinanky Jadhav, Pune
