There's no need to skip meds for 48 hours, 24 hours is ample for Levothyroxine.
FT4 and FT3 are low in range. Fine if you feel well but, if not, and you are symptomatic, ask your GP to increase dose. You weren't overmedicated on 150mcg so I don't know why your GP reduced dose to 150mcg.
The goal of Levothyroxine is to restore the patient to euthyroid status. For most patients that will be when TSH is 0.27 - 1.0 with FT4 in the upper range. FT4 needs to be in the upper range in order that sufficient T3 is converted. Read Treatment Options in thyroiduk.org.uk/tuk/about_... Email dionne.fulcher@thyroiduk.org if you would like a copy of the Pulse article to show your GP.
Ferritin is optimal halfway through range. You can raise ferritin by supplementing iron with 1,000mg vitamin C to aid absorption and minimise constipation. Iron should be taken 4 hours away from Levothyroxine.
VitD 39 is insufficient. My sister's GP prescribed 2 x 20,000iu D3 per week when her vitD level was 40. VitD should be taken 4 hours away from Levothyroxine.
Thyroid antibodies are negative for autoimmune thyroiditis (Hashimoto's).
If your GP refuses to prescribe you vitamin D supplements OR if you are only prescribed 800IU, please come back here and start a new thread asking how to raise you vitamin D levels.
