Slow Responder to Isotretinoin? When Can We Expect Results?

My son is 15 and 165 lbs with moderate acne. He took isotretinoin 40 mg first month, 80 mg second month, 100 third month. His 3rd month will be finished in 5 days. His face still looks worse than before he started taking the drug. He is quite frustrated. He had a very positive attitude and had been very patient, but it has become very hard to put up with all the side effects and still see so much acne breakouts. Please let me know if this is common and when he should expect results.

We would expect to see some improvement after the 2nd month. Some of the spots, usually the deeper white cysts, may take longer to improve, but the red pimples and red cysts should be getting better and there should be few... more

Slow responders to Accutane

I would meet with the doctor and discuss this situation, as I would not describe the situation you've stated as common. I've prescribed Accutane to tens of thousands of people over my nearly 30 years. The minimum effective dose for Accutane is 1 mg per kg of weight per day for at least 20 weeks, for very mild to moderate acne. You describe your son's acne as moderate, so with that being said, he should be about 12 weeks into the medication. What you've stated, quite frankly, are dosages I've... more
