Hello @annedodrill44

We have had members discuss those sort of problems related to use of Synthroid. Are you taking the generic version or the brand name. Several Members have discussed that their doctors insist on the brand name rather than a generic.

Here are some discussions where the difficulties of dosages of thyroid meds are mentioned,

Have you discussed these side effects with your doctor? It might be a good idea. If your doctor does not understand the problems you are having you could certainly get a second opinion.
