I have been taking metformin for 15 years. Then 4 yrs ago my doctor changed it to januvia because metformin wasn't working that good. Then my plan was with cvscaremarx. There was no issues getting my medication. Then january, 2021 optum took over my plan. From day one, they have been harrasing me to change my medication. Basically they are deciding which medication I should take. Finally they arbitrarily refused to send me the medication. I pleaded with them its a maintenance drug. I need to take it everyday. They didn't give a damn. They were acting like empowered legel mafia. I even pleaded if I don't take the medication I will go in a coma, for now to give me a months supply and then we figure out. They refused. That's how optum manipulate with my medication.
