Does anyone know if birth control pills effect Phentermine? I lost 40 pounds with it before but since after I had a baby and am on birth control now, it doesn't seem to work as well now or is this just me?

I have used phentermine on two separate time periods to lose weight. My doctor told me that the longer you use it, the less effective it becomes as your body becomes immune to it. I definitely felt the effects the second go-round. She told me it does not effect birth control. Good luck on your weight loss. Phentermine definitely makes it easier!
