I'm not sure, but you can always ask your doctor, or check online... I think its orthotricyclenlo.Com or something similar to that. Search it on google, it's there.. I know because i've been there.

Use caution after you have lost weight!!I know more than a few ladies who got pregnant after losing a bunch of weight.Check with your doctor to see if you might need an increased pill after your loss.Hope you get the results you want!!Just don't end up like anna nicloe!!!(poor thing,just can't get it together!!)good luck!Patty
