Do you have TSH, FT4 and FT3 results and ranges for when you were taking Levothyroxine only? Unless FT4 is top of the range there is no need to reduce dose when adding T3. FT3 4.83 isn't unduly low. How long have you been taking 50mcg T4 + 12.5mcg T3?
You were undermedicated on 100/50mcg alternate days to have TSH 2.86 and T4 was was only mid range. I would reinstate 100/50mcg along with 12.5mcg T3. I would stick with that for 6-8 weeks and have TSH, FT4 and FT3 checked to make sure FT3 remains within range.
Hi clutter... so I have been on levothyroxine plus t3 25mg split in half but since Thursday I've been getting shivers and muscle ache, could this be the t3 or could I just be coming down with something. Should I stop taking t3? I've been off sick since Thursday and by the looks of it won't be able to go in tomorrow. My lower back muscles also really hurt, arms, legs and kind of flu symptoms but without the runny nose or sneezes, my throat feels a bit sore to.
If you've felt unwell since starting T3 it may be that T3 doesn't suit and it may be worth stopping T3 to see whether symptoms improve. If you've been taking T3 for 3 or 4 weeks and suddenly feel unwell its more likely to be a virus or flu. I hope you feel better soon.
Have you had vitamin D, folate, B12 & ferritin levels checked? These are common to be low & we need them at high end of normal range to utilise thyroid hormones (our own or synthetic ones)
Do you have Hashimotos? (High Thyroid antibodies) if so are you on or have you tried gluten free diet?
Unfortunately, Dr Lowe died of an accident and the above is from a book and his website has been removed. He also wrote a book about Thyroid Hormone Resistance - The Metabolic Treatment of Hypothyroidism. You might be lucky to come across it.
