Always ask your doctor. I take Januvia and am on both amaryl and metformin/stiglapatin on top of that. There should not be any drug reactions, just will have to watch your sugars with any change and let your doctor adjust the dosing. Good luck

I was on Januvia I had to get off I bought pancreatitis has no cure. No other pain is close to it not even morphine will take it away. I was in hospital for 39 days.

Talk to your Dr. or pharmacist.

If you want to change meds you must ask your doctor and hope they are up to date on new meds.
