Accutane (Isotretinoin) is considered completely gone from your system 30 days after your last dose.  Donating blood and pregnancy should be avoided until then.

Since the medicines 1/2 life (time it takes 1/2 of medicine to be cleared form your body) is 21 hours, the vast majority is cleared by 4 days.
