My Cytomel 5 mcg tablets now have a new appearance (KPI on one side, 115 on the other). I was informed by the pharmacy that there was a change in manufacturer but haven't been able to find any mention of this on the Internet. I'm assuming that with a change in company, the formulation stays the same?? I'm always reticent to make changes in a medication which has been working well for me. Any info for this novice pharm-switcher is greatly appreciated.
