TF4 has dropped even more after medication

[juliva]

I was wondering if anyone could tell me why my hubby's TF4 would drop to .98 from 1.1 after being placed on 75 mcg levoxyl for one month?

My hubby was dx with hasti's just over a month ago. Endo prescribed levoxyl. At the time of Dx his TSH was 8.22 and now is 2.94. TF3 is 270. I'm not understanding why his TF4 has dropped? Endo has instructed him to take a extra half of his med only on Sundays. Just not liking that TF4 dropping can anyone explain why this would happen?

Also, his testosterone is low... Endo said this can happen in men with hypothyroidism and he will be placing him on meds for that as well.. not sure if this makes a difference in anyway?

TSH    Ref. Range  0.40 - 4.50
T4 Free                  0.8 - 1.8
T3 Free                 230 - 420

Thanks! Doc has increased but he's only been on meds for just over a month. Thanks again!

Considering all the possible contributors, such as progression of the Hashi's, along with lab test variability, that change is nothing to be alarmed about.  More important I would think is that both FT4 and FT3 are in the lower half of their ranges, which frequently is associated with hypo symptoms.  Many members report that they feel best when FT3 is in the upper part of its range and FT4 is at least at the midpoint.  

If your husband is still having hypo symptoms, likely it is time for a med increase.

At first I thought the same thing but after I thought about it I thought it seemed to be a bit extreme after taking that much med. I don't know for sure but I'm thinking there has to be another reason.  Maybe he needs another medication.. I guess it's a wait and see. Thanks!

Maybe the hashi's is progressing, with his thryoid getting less able to produce hormone over time.

Be patient and keep testing, it can take a while to get levels optimised.

Target TSH would normally be around 1.0a nd FT3 and FT4 in mid to upper half of the reference range.
