Forum Name: Carcinoid Tumor

Question: Long-term phentermine use and carcinoid


 wellwisher - Fri Jan 27, 2006 10:24 am

Age 43
Female
Past Diagnoses & Surgeries - gastrointestinal stromal tumor - resected 9/03; hysterectomy, carcinoid tumor in appendix -resected 1/04
No family history of cancer
Current Rxs - singulair; wellbutrin XL; zyrtec; vivelle dot; proventil as needed; phentermine

Four years ago, "Turn off the Hunger Switch" by Dr. Paul Rivas convinced me his recommended therapy of phentermine was the answer to my problems and that long-term use wasn't a problem. I've been taking phentermine ever since.

I've been having symptoms again similar to what I experienced when I had the carcinoid tumor -- flushing on face & neck, raynauds in my fingers and toes, abdominal pains. Could a carcinoid tumor be caused by long-term phentermine use?

Thank you for any info you can offer.

User avatar Hi wellwisher,
The use of phentermine is recommended only on a short term basis (not long term). There has been documented associations in regards to heart/valve disorders as well as carcinoid syndrome/tumors. I would question the long term prescribed use of this particular medication.
Sincerely,
Theresa Jones, RN
