Overmedicated


The tsh should be 0.86 not 86

Last test 3 weeks ago
How much eltroxin were you taking
50mcg or 75mcg ?
was latest test done as recommended early morning, ideally just before 9am, only drink water between waking and test and last dose levothyroxine 24 hours before test
How long have you been on 75mcg
When were vitamin D, folate , ferritin and B12 levels tested
What vitamin supplements are you taking
I've been 75 mg for 12 weeks. Ferritin etc All good . Test taken 24hrs after last dose on empty stomach.
it’s 75mcg (not 75mg)
So discuss with your Dr reducing dose by SMALL amount
Eg to 50mcg 2 days a week and 75mcg 5 days
Or 62.5mcg daily ( 50mcg plus half a 25mcg tablet per day)
Retest in 8 weeks
What are actual vitamin results
Do you have Hashi's?
Yes
Then the sudden rise in FT4 is far more likely to be due to a Hashi's 'hyper' swing than to your dose, which is quite modest. 75 mcg levo is unlikely to make you over-medicated.
