Like "I was on Metformin 1000mg 2x daily 1000 morning 1000 evening. I have recently been switched to Janumet same dosage because of anemia from being on Metformin since being diagnoised. Am doing fine on the Janumet and Januvia that I take so watch out if you have been taking metformin for a while and make sure you are not anemic. I didn't even know I was until the Dr. put me on Iron."
