Hello doctor,I completed my acne treatment one year ago and my skin is clear after some period of time. My scalp and face get excessively oily. So I went to another dermatologist and he says that the treatment is under weight. My weight is 55 kg. I take Isotretinoin 20 mg for four months, 10 mg for four months. So please advise me who is correct for me to treat my skin.
Hello. What you have told is correct. To prevent relapse of acne one needs to complete a total dose of 120 mg/kg of Isotretinoin. As your weight is 55 kg you should be taking a total of 6600 mg of Isotretinoin to prevent relapse. That comes out to be 330 days of 20 mg per day of Isotretinoin. That is almost 11 months of 20 mg Isotretinoin. This dose is recommended to prevent relapse of acne.
