Also remember that hormonal contraception pharmacokinetics also depends on adipose tissue and skin surfaces. More adipose tissue means less biodisponibility. Less biodisponibility means more chance to breakthrough bleeding and pregnancy rates.

The American Medical Association is no longer designating CME hours for AMA Category II CME credit. However, physicians themselves may self designate learning activities as Category II CME credit hours if they feel it is of sufficient educational merit and meets the formal definitions of continuing medical education. OBGYN.net believes these interaction in this forum meets these criteria. For further information see the AMA web site.
