ipledge will tell you exactly when you can get your prescription filled. You have to first have your blood test, then see your derm and do all the ipledge crap THEN you can pick up your pills within 7 days (of your blood test). It's a pain in the ass, every month. Usually I pick mine up the day after my last pills ran out. It's timed that way though, with my appointments.
I am assuming you are from the USA, but maybe not? It's different in different countries.
Good luck!!
Yeah I'm on my first month now... I just was wondering because if I get my blood test done and I have to pick up my prescription in 7 days then I still have pills left. But ipledge says I could get my next bloodtest done. I'm so confused. My dr won't know either... It's just my family dr, not a derm.
