Phendimetrazine is an amphetamine mimic - basically speed. According to the WebMD site, it is also habit forming and has some pretty nasty side effects.
That in itself would keep me away from it. Losing a few pounds isn't worth it IMO...not to mention this is EXPENSIVE STUFF.
Question: If your friend has lost weight on the drug...how long has she kept the weight off? Is she able to maintain the loss without the Phendimetrazine?
I'm sorry, I've just known too many folks who have had their lives screwed up by using speed in its various forms (legal and illegal). You're better off staying far, far away from it. Face it - there is no majic weight loss pill...
If you insist on taking this, I would highly recommend that you visit your personal doctor. I realize that it prescription weight loss drugs are available (at HUGE prices) on the Net without having to go see the doctor...but if you have any heart problems or medical issues at all (that you might not even be aware of) this can be QUITE a dangerous substance.
