Please can anyone tell me where I can get a lactose and gluten free form of thyroxine that doesn't cost the earth!? My GP said there aren't any. I did some research and discovered Eltroxin and called Mercury Pharma today who said it is unavailable now but that they have oral solution levothyroxine that is lactose and gluten free. It costs around £60/bottle. I would need two bottles to give me the 75mcg I would need/ day which would only last around 20 days as each dose is 5ml. I think I've done my maths right! I can't see my GP willing to pay this each month. Does anyone know why it is so expensive compared to the tablets or if there is something else I could take? I've been taking levothyroxine in tablet form for nearly 20 years but with ongoing health issues that I'd like to rid myself of which may be caused by my daily consumption of small amounts of lactose I believe.
