Hello to everyone, this is my first post here.
I was diagnosed with micro papillary with follicular variant in April of 2007 and underwent a TT followed by 209 mCi RAI. I've been on various doses of synthroid for the past 10.5 years.
Most recently, I switched to NDT ERFA on August 11, 2017 from 175mcg Synthroid alternating with 162.5 every other day.
Back in late September my endo had lowered my dosage of ERFA from 90mg daily to 90 alternating with 60mg. I stayed on that dosage for a while but had a lot of issues being that low so I upped it myself to 90 alternating with 75mg. My to labs prior to lowering (on 90mg daily) were as follows:
FT3 5.8 Reference Range: 3.5-6.5
FT4 10.1 Reference Range: 9.0-23
TSH 0.03 Reference Range: 0.20-4.00
My endo insisted I lower my dosage even tho I told her I felt great. My latest labs are as follows:
FT3 4.4 Reference Range: 3.5-6.5
FT4 8.2 Reference Range: 9.0-23) I've been flagged as low
TSH 0.79 Reference Range: 0.20-4.00)
Thyroglobulin 0.2 (was 0.1 in January of 2017 when I was on Synthroid prior to switching to NDT ERFA)
Antithyroglobulin antibody less than 0.20 (ref less than 40)
My TSH has gone up a lot in a little over a months time and my FT4 is too low. My family doctor had the office phone after my labs came in and wants me to go back up to 90mg daily based on the latest labs. I met with my endo and she agreed with him and now I'm back on 90mg daily.
I've been feeling pretty awful; really depressed affect, no energy/stamina, sluggish digestion, etc.
I've tried dividing my dose into 45mg twice daily as well as 30 three times daily. Ive also tried taking 60mg in the am and 30 in the afternoon and visa versa. I've even tried to take 30mg in the middle of the night and the other two doses of 30mg at 8am and 2pm.
Nothing is helping me to feel appreciably better; to the contrary, I keep feeling worse as time goes by.
Another issue that is really bothering me is that of weight gain. I seem to be putting on weight since going on the NDT (was on Synthroid for over ten years) even though I'm eating/exercising the same as always. I don't want to give back and go back on Synthroid and could really use some advice.
