Discussions that mention synthroid

Thyroid Disorders board


Please give me your opinions and ideas. I asked the doctor for T-3 medication becasue I think I need it. The doctor replied that I did not need any T-3 or T-4. She said taking Synthroid provides my TSH levels with what is needed. The doctor said my levels of T-4 and T-3 were normal...I just needed TSH. The doctor said the test did not test for T-4 or T-3 becasue the levels were not important like the TSH level was. Comments, please. Thanks.
It would help if you gave some background. How and when were you diagnosed? What were your symptoms or was a problem found on routine blood work? Are you being treated by a GP, NP, or endocrinologist and for how long? What was your most recent TSH, how much Synthroid are you taking and for how long, and why do you think you need cytomel?

At the least, a doctor treating a hypo on replacement should run the FT4 with the TSH. Adding an FT3 is ideal although some insurance companies won't cover it because it's more expensive (FT4 around $30, FT3 around $175+ from what I've seen). People taking any T3 drug (Cytomel or a combo like Armour) need the FT3 run routinely, but I do know people on just T4 who check the FT3 once in a while--every third lab--but who usually monitor by TSH and FT4 alone.

No one on replacement hormone should be monitored just using the TSH. It's a fine test in itself to screen people routinely for thyroid problems, but it is not fine in itself for people receiving replacement hormone in any form.

Hi, thanks for your time. I have been taking thyroid medication since I was 16 and now I am 45. I began taking Euthroid and in the 80s I begin taking Synthroid, instead. I have always taken .125 mg.
I moved to another state. In order to get the new doctor to prescribe Synthroid for me, she ordered lab/blood work.. She changed/decreased the dosage from .125 to .112 because she said the THS was low. She said she did not check the T-4 or T-3.
I have very dry skin and am gaining weight. I have dark circles and bags under my eyes. I am always cold. I have low body temperature....I have all these signs of low thyroid and other symptoms, too, even though I am taking the Synthroid.
The doctor says I need nothing else...Thanks.
No offense, but I would switch doctors. I go to an endocrinologist and he tests my TSH, T3, and free T4. If you are still having hypothyroid symptoms, maybe your t3 and t4 are still low even though your tsh is normal, it is very important to test them. Also, I dont know what your doctor is refering to when he/she said that synthroid provides your tsh levels with what its need and that your dont need to take t3 or t4. Synthroid is t4. And yes tsh, is important, but it could miss low grade hypothroidism if you only test the tsh and not t4/t3. Try another doctors opinion. you could also suggest a trial run of t3.
