Reporting Groups

Subjects will be treated with isotretinoin initially at 1mg/kg for the first 4 weeks and then dose will escalate to a higher dose only if subjects have tolerated the lower dose.

In younger patients of 16 and 17 years of age, the dose will be started at 1 mg/kg and will remain at this dose without escalation.
