Wishing effects of Accutane lasted longer than 6 months, should I do a second treatment?

It is not unheard of to have to repeat a course of Accutane.
There are many variables in place such as skin type, severity of acne, and
dosage that determine this. If you are starting to break out more and more, a
second opinion from a different dermatologist may be helpful.

The key to making Accutane work is the total cumulative dosage, which is usually between 8000-16000mg total. Your dose that you have listed gives you a total cumulative dosage of 4200mg. So you barely got halfway through what is considered the normal recommended dosage. I'm sure your acne cleared up while on it, but there was no way that the pores and glands changed enough for a long term cure. Bottom line, you need to do it again, and be on the meds longer, or on a higher daily dosage.
