I am 35 yrs old woman with severe acne. I want to start isotretinoin, Can I start whilst on my period/ after/or before?

Thank you for your question. Accutane treatment can be started at any time in regards to your menstrual cycle. However, measures need to be taken to ensure that you are not pregnant prior to starting therapy. I highly recommend you consult with a board certified dermatologist regarding your questions and concerns about Accutane. Take care and good luck.
