I have been taking Synthroid/Levothyroxin for 13 yrs

[GitGirl20]

I have been taking this medication for 13 yrs and get my blood tested regularly. I can't understand why they have me on the same dosage and it has never changed. I am starting to feel like its not working for me but they say my levels are fine!!! I have been on this for so long that I know the ups and downs and how it feels to be off of it. I feel like I am off of it even though I'm not. What do you think is wrong with me? Do you think that I should see another doctor? Do you think that I should go back to the brand name Synthroid medication vs. Levothyroxin?

Also, I have never had children so I know that can't be the reason. Thanks so much!

Do you know the actual test result numbers, so that you can evaluate them against the ranges yourself, and not just be told "they are fine"?   If not, I suggest this as a first step to taking control of your own health.  I also suggest that you take your basal body temperature.  Many years ago BBT was shown by Dr Broda Barnes to be a very reliable indicator of metabolism  and thyroid levels.  Take the BBT in your armpit, before getting out of bed.  Dr. Barnes established  a normal range of 97.8 -98.2.  The lower you are below  97.8, the greater the need for medication.  If you want to read about this there are many references on the net.  Look for Dr. Broda Barnes.  Please post results so other posters can pick up on this.

If the levels are stable (goal is TSH 0.5-2.5) then would be hard to pin the symptoms on the thyroid.  Staying on the same dose is not uncommon...

If the generic is keeping levels consistent, then there is no definite benefit from switching back to a brand in most cases, but that would not be unreasonable.
