Slightly Low THS

My T-4 and T-3 are normal with slightly low .1 TSH.  I have other health issues.   I have been on Synthroid .125  for 25 yrs and Cytomel .5 for the last 5 years.  This new doctor wants to drop my Synthroid to .100 and add Prometrium.  This started a week ago and I feel so crappy.  My main problem was inability to sleep.   Does it make sense to drop your thyroid meds when your TSH is only slightly low?  The prometrium knocks me out, but only for a couple of hours and then I am wide awake again.

Go back to your regular doctor.  This one doesn't have a clue about thyroid.  You were stable, you were feeling well.  Now, this new doctor is messing with your dose because she's just looking at TSH and has no clue how to use it in someone taking Cytomel.  Don't put up with this for 30 days.  You will feel less and less well if you do.  Call your regular doctor and explain how bad you feel since your dose was reduced.

I had been seeing this GP for about 4 years and she had been putting me on hormones and she added the t-3 then.  She brought in a young new internist and I went in for required insurance annual physical and she is the one changing my dosage and telling me I need to change my dosage.

Those labs were done just before the decrease?

Actually, I see no reason whatsoever in your labs to lower your dose.  Your FT4 is in the bottom third of the range, and the rule of thumb for FT4 is midrange.  FT3 is just a little above midrange, and the rcommendation here is upper half to upper third.  So, your frees are a bit on the low side if anything, and an increase might actually be indicated.  TSH is a pituitary hormone and can be influenced by many factors other than thyroid hormone levels.  Cytomel will lower your TSH, so TSH is no longer a reliable indicator of appropriate meds dose.  It sounds like your doctor is going by TSH alone, and that's a very bad thing.  He needs to look at the frees and adjust them, not TSH.

Did you go to your doctor with complaint of symptoms, or did he just run routine lab work and decide to lower your dose?  I wouldn't stick it out for 30 days...you'll just continue to feel worse.  Did you have previous labwork to show your new doctor so that he could see you history?

Sorry about that.  T-3 is 3.3 with range 2.3-4.2 and T$ is 1.04 with range 0.73 to 1.95 and TSH is 0.1 with range 0.3 - 5.1.  I guess I will just wait it out until I retest in 30 days.

On your lab report, next to the results, there should be a reference range, probably in parentheses.  For FT3 is should be something similar to (2.3-4.2).  We need the ranges for FT3 and FT4 along with the results.  Was your thyroid removed, or did you have RAI, or both?  If so, when (approximately).

The symptoms you list could all be thyroid symptoms (symptoms that your meds are not adjusted correctly).

Free t3 is 3.3 PG/ML  and Free T-4 is 1.04 NG/DL.

I had Graves Disease in my 20s, Hep C due to transmission in the 80s, recently diagnosed with Lupus, but doctor still pondering that diagnosis.  Having a lot of health problems with joint pain, fatigue, tendonitis, and the new changes with thyroids meds seem to make matters worse.

Please post your actual FT3 and FT4 results with reference ranges (these are lab specific and have to come from your own lab report).

Cytomel, or any meds with T3 in them, will suppress your TSH.  Once on T3 meds, TSH has to be discounted in most cases.  

What are your other health issues?  Do you have Hashi's?
