Just a heads-up here. I am on lio only as, after many years of levo, I developed reverse T3 and had to take more and more levo to control the thyroid symptoms, which resulted in atrial fibrillation. This is under control and indeed absent as long as I take lio only. My cardiologist was incensed recently when a GP asked me to trial levo again and said I was not to take it under any circumstances. My endocrinologist concurs.
Today, after a routine GP appointment, I learned that the government is proposing to stop all prescribing of liothyronine as it is on their list of "items of limited clinical value" since they say it has no beneficial effect and there is no evidence that anybody needs it! Ultimately, if their plan is approved, no GP will be able to prescribe it on the NHS since it is a costly medicine (£700 per 28 tablets).
The only way around this for people like me would be to go to the approved endo (at my own cost, privately) , get them to approve the necessity of prescribing and receive it as a private prescription, for which I would obviously have to pay.
I am therefore alerting any others in similar positions that this is not yet the law but may well come about. The document can be found at:
