My dermatologist prescribed me 20mg for mild to moderate but persistent acne. She only asked me to take it for a month. I heard that you should complete yourcumulativedosage depending on your weight to make sure your acne doesn't come back. I've been taking it for a little more than a month and my acne has cleared considerably. I have no new acne spots since past two weeks.

My question is: Should I take 20mg for 10 months -- which is my cumulative dosage -- even after my acne has cleared in a month or can I quit it after like 2 or 3 months?
