I have to request a prescription monthly & is normally for 28 days. This month following blood test, & comment from lab re TSH, again being 0.05, the surgery have requested a phone appointment (earliest date is 4 weeks away) to discuss. They have on my records that I am 'serviced' by an endo and that despite TSH not altering following reduction in T3, my T3 result is now in range, albeit at the top (where we want it to be!) No one has contacted me to say why they are only prescribing for 21 days, assuming they are concerned re TSH score, as that is all that matters to them. I should add that my endo is not obsessed by TSH. Has anyone else had this happen, I hope they are not looking for an excuse to refuse to prescribe again?
