I have a NHS GP prescription for cytomel. It is currently out of stock with overseas suppliers . GP is very unhelpful. Is all T3 medication unlicensed in the UK or just cytomel? What is an alternative that can be prescribed and readily available in the UK. I have been on 12.5mcg per day taken in conjunction with 100mcg levothyroxine.(t4). Also I have a medical exemption card as pharmacy advised that thyroid medication qualifies for exemption (I am a Brit who has just returned from living/working overseas from many years). I have seen that many of you are paying for your meds. Why hasn't everyone on this forum got exemption cards?
