Question: Phentermine Sexual Side Effects?

 damnws6 - Sun Sep 23, 2007 4:07 pm

Hey, I am currently taking Phentermine for weight loss under doctor supervision. I'm on my fifth day. Since I've taken it my penis has become smaller when flaccid, my strotum is shiveled and raised up (as if I were cold), and my penis is so far it sometimes that the foreskin covers it (I am circumsized). Also my sexual drive seems to have lessened, to get an erection it takes quite a bit of time compared to before. I've taken Phentermine almost two years ago with the same doctor and experienced a little loss in sex drive but I was also on pain medication for a herniated disc. However I don't recall my penis being as small and as in under the foreskin as now. Is it the Phentermine that is causing this? Also is it harmful and show I discontinue use? The Phentermine is working for my diet and I can live with the loss of sex drive since it is temporary but if I continue the use of the drug will I experience permanent sex drive loss and a smaller penis?

User avatar I am sorry for the delay in answering the post. When you add a comment to your original posting, it comes up appearing to have been answered so we overlooked the question.

Yes, phentermine has been associated with sexual side effects but they should be transient so it is worth it to put up with it while losing weight. That will improve your health significantly. No permanent effects would be associated with this if it is the cause of your troubles.

Good luck on your efforts to lose weight. It is a hard thing to do but can add a great deal of quality to your life.
