Justin G (3 years ago):
I am 28 years old I have been on phentermine for the last month and and 2 or 3 weeks. In the last month i started noticing blood in my stool but it was very painful so i wrote it off as Hemerroids and or a fisher. This pain and blood has now been going on for over a month. The pain is begining to subside as i think the hemerroid and or fisher is healing. But the blood has gotten worse. I still have a week or 2 left of my perscription. I am Just going to stop taking it and hope that the bleeding stops. I am extremely scared cause i have never had this much blood before. I only say that because i have had hemerroids or a fisher before but they never lasted this long either. I am extremely worried. And i cannot afford to go to the dr right now.

- Weight migain with phentermine
I took Phentermine in 1990. At the time I only had about 20 pounds to lose. I actually lost 30. When I stopped taking it, it was like someone opened a "fat door". The weight started coming back even though I did everything exactly the same as when I was on the drug. In six months I had gained 120 pounds. To this day, I cannot get it off no matter what I do. I have been called a liar by several doctors, and have tried every diet known to man. In addition I spend three years with a personal trainer. Nothing has worked.
- Taking phentermine likely caused our baby to have anencephaly.
I used Phentermine for a few months prior to my wedding in December 2013. I ceased taking the phentermine in December 2013 after my honeymoon. In January 2014 my husband and I conceived a baby boy. This was our first child together and we and our families and friends were elated with excitement. At 9 months I had my first ultrasound where you can clearly see our baby's skull was not closed. The on/gyne who took the ultrasound did not diagnose the anencephaly or alert us, instead he referred us to the maternal fetal department at our local hospital. A month later I had another ultrasound performed at the maternal fetal department and was immediately informed and shown that our baby has anencephaly and an abortion was required. The only medication I took prior to pregnancy was phentermine prescribed by my primary care provider. I believe the phentermine is chemically composed similar to Adderral and should have the same warnings. I also believe phentermine causes a mother to be anemic and unable to provide a baby en utero the necessary nutrition for healthy growth. Had I been informed of the risk, I would never have taken this medication. Our baby died at 14 weeks after we were forced through the anguish and torturous of a late term abortion which is against our beliefs. I am now pregnant again, this time with a healthy baby.
- Trigeminal neuralgia after use of phentermine (2 responses)
I am insulin resistant, unable to lose weight w/diet and exercise. Started us of Phentermine for about 6 days and had increasing symptoms of abscess tooth. Went to dentist, was not a tooth, he thought it was a sinus infection. Antibiotics did not work. My PCP gave me more antibiotics. Did not work. Went to ENT- scoped sinus. It was not my sinuses. Told to take different antibiotics if pain came back. IT DID! Took those, went back to dr- Worse still. Dx with TMJ, given muscle relaxers. That did not work. Pain continued intense. Unable to chew, wear glasses, move my hair, sleep on that side of head. Dx w/Trigeminal Neuralgia. This started with the Phentermine. I want to know if anyone else has suffered this?!
- Effexor xr 150 mg and phentermine 37.5 mg
phentermine has caused significant weight loss. Effexor XR manages my GAD and depression but causes random physiological anxiety attacks, drastic increase in sweating, vivid and nightly nightmares
