phentermine and an underactive thyroid - Phentermine.com

txcntrygrl · July 6th, 2004, 10:50 AM

Are any of you taking phentermine and suffering from an underactive thyroid?

I am not on phentermine but I want to be but I heard that you cannot take it if you have thyroid problems. I have done some reading and it says it pertains to those with an overactive thyroid. I have read about several people taking phentermine and their thyroid meds with no problem but I would like to read more. I am going to start taking b-12 shots on Thursday and the dr is going to look at my bloodwork to decide if I can take phentermine.

Hellol....I take .125mg of synthroid everyday and 30mg of phentermine...no issues at all...I think there is a problem with phentermine and OVERactive thyroid, though...good luck!!

i also have hypothyroidism and have no trouble with synthroid and phen. I take synthroid when I first get up about one hour before I eat.and phen one hour after breakfast.

There is a problem with hyperthyroidism and phen. Can't mix the two but most hypers are too thin, not heavy.

Hello...I take them all together before I go to the gym with no problems...and I think you are right about that...its the hypers that cant take phen.

:::Gem::: · September 2nd, 2004, 03:50 PM

same here, I take syndroid. Can't really say if there will be a problem because I started today on the phen, but I doubt it.

I think it's more of a hyperthyroid problem then it is a hypothyroid issue.

I took it when i had to take thyroid meds also i actually found out bout my thyroid when i was taking the phen/fen meds...it didnt bother it any
good luck

I had my thyroid removed 5 months ago and I am on Synthroid which is finally regulated.I have no trouble[besides the usual side effects] taking 1/2 of 37.5mg tab but my weight loss is slow,about 1 pound per week.

What kind of diet is working for most of you? I have gone back in forth from low fat to calorie counting,to Atkins? I need to lose weight fast.

Cubidoll · March 16th, 2005, 12:41 PM

I have underactive thyroid and my thyroid doctor gave me phen and I have no problems. Is going slow but I knew that would happen because our illness. Aslong as I lose that what matters. I have patience.

I have been on Synthroid for 11-12 years and was put on Phentermine 1-1/2 yrs ago by my Dr.s Phys. Assistant. He also increased my Synthroid from .100 to .125. I lost 35 lbs in 2 months. Of course I was on a strict no carb diet and treadmill daily. When my Doc realized what he had done, she stopped the Phentermine abruptly and dropped my thyroid back to .100. This led me to ask my Pharmacist about mixing the two and she said she agreed that it is irresponsible to put a patient on both.

I recently asked my Doc to up my thyroid to .125, which she did, and I mentioned the Phentermine thing. She said she stopped it because she figured I wanted to live a bit longer. Now Im a bit confused as my Doctor and the Pharm both were quite adament that the two don't mix. I really would like to take Phentermine again, but I don't dare ask.

The only side effects I had at that time was a numb feeling of my face daily and mostly in the afternoons.

Confused

I am also hypo. and I take a mixture of Armour Thyroid/Synthroid. On the drug interaction checker, there are no interaction problems between thyroid meds and Phentermine.

queenmama99 · May 2nd, 2005, 05:13 AM

I take Levothyroxine at the dosage of 200 my dr and pharmicist both said there was no worries with this combo, I believe if you are HYPER then there is an issue, but not if you are HYPO.
