Norethindrone Birth Control How Long Until Effective - MySport

My pelvic pain specialist/surgeon is trying to control it (and stop my cycles) with progestin-only therapy; soon I'll be changing from Norethindrone to Megace for it. The other hormone of importance is progesterone which obliterates endometriosis. An alternative to stopping the estrogen would have been to continue it along with norethindrone, a synthetic progestin, in a patch product called Combipatch by Rhone-Ponolac-Rhorer.

Or this could have been done orally with Searle's Lo-estrin 1/20, taken every day.
