You start at 5mg? I started at 40mg a pill and take it once a day. I'm on my 2nd month now and it's still the same type and I eat it once a day like last month. I advise calling your doc just to be sure. Overdosing on Accutane can be really serious.

This is not something to be taken lightly. Accutane can be very dangeous. Consult your derm right away, don't worry it's an honest mistake happens to the best of us.
