A course of Roaccutane/ Oratane is highly variable, and will depend on several factors including the type of acne, your side effect profile and your weight. As a guide, most patients will need to undergo a 6-8 month course, back acne patients / bacne patients will need at least 12 months.

Most Specialists now elect to use a low-dose isotretinoin regime as this has a much better side effect profile- the flip side is that patients may need to be on Roaccutane a few months longer to reach remission.
