I was just wondering if anyone out there has had an allergic reaction to phentermine. I've been on it for about 2-3 months now and have been doing fine. Last week I started to get hives/swelling and irritation of my face, and couldn't figure out what could have caused it. I haven't started using any new creams/washes/lotions, etc., and I don't have any known allergic reactions to different foods.

The only other thing that I could come up with is the warning on phentermine that it may cause swelling/hives of the face.

Anyone else have this problem? I would really appreciate any feedback.
