After months of being on different doses of levolthyroxine, it Is likely that I need to take 80 mcg of levolthyroxine, but that is not available, but if the drug companies produced a 5mcg this would be helpful, as it could be added to another dose, there by achieving the correct dose. I'm sure I am not the only one that needs a different dose to what is termed normal. Does anyone know of a company that produces a wider range of doses?
