FAQs about Accutane’s side effects

Will my acne get worse when I start Accutane? 

Some people find their acne gets worse before it gets better, this is sometimes called the “accutane purge” which can happen in the first couple of weeks to the first few months of treatment.  This can be an increase in the number of pimples or can be a major breakout with skin more inflamed and irritated.  Usually Accutane takes 2 to 3 months to show an improvement in acne, if you are concerned about how your skin is responding to Accutane you should discuss this with your Dermatologist. 

These are not all the possible side effects of Crestor. Tell your doctor if you have any side effect that bothers you or that does not go away.
