Accutane Treatment to Begin Soon when to Stop Minocycline?

I am 44 and always had acne, not severe but persistant and scaring with my olive complection. Doc tried everything else OC & precrip creams and antibiotics. So Accutane is next. I am still on Birth control (for acne only had tubes tied18 yrs ago) minocycline & Aczone cream untill I see the Doc at end of 30 day wait period. Question, how long before begining Accutane treatment should I stop taking the minocycline. Or is there a need to stop more than a few days before? I will ask my Derm. also.
