    Hi and welcome! While I don’t have experience on methimazole – I do have experience on multiple levothyroxine drugs. I personally noticed a difference in how I felt/physical changes between the various levothyroxine generics and brand name drugs. While the active ingredient is the same, the fillers and as Kimberly noted the absorption can vary between manufacturers. When the pharmacy decided to switch things up on me I just asked my doctor to write the script for the specific one I liked/my levels were stable on/I personally felt my best on. It did take me 8-9 months to ask – but eventually I did.
