It's exactly a year since I first started on Carbimazole (40mg/day, titration).
This may seem like a very small thing, but apart from a period last October where my TFTs went straight through the range, and dropped out through the bottom, my results have been obstinately above range. Ok, so I was still on 30mg/day Carbimazole when the bloods were drawn, but even so.... FT4 18 (9-22), FT3 6.5 (3.5-7.8)
My endo is still concerned that my thyroid is proving difficult to get under control, and he did say we might need to talk about 'other options'. He listened when I said that I felt it was a bit soon, and agreed when I said that my main concern was that the treatment was irreversible. He's signed me off to stay on carbimazole for another six months before we discuss 'other options' again. He also mentioned that he'd heard of a small study in China where they'd had a 65% success rate treating a first relapse with anti-thyroid treatment, and that although this has yet to be replicated, he was willing to give it a go.
I'll take this for now. I do get that if my thyroid levels really can't be kept under control by no more than a low dose of carbimazole we may have to discuss those 'other options' again, but for now, it feels as if I'm in with a chance
