I'm going in to my third month on mounjaro. When I reordered I decided to stick with the 5mg dose however I think this was a mistake. Someone I know ordered the 2.5 and then decided not to start the medication and offered me the pen but I declined as it was the lower dose than what I was on but, someone suggested I take both to make the 7.5mg? But something tells me this is a bad idea? Would it work? Any obvious reasons why it wouldn't?
