I am currently on this and I have not had any weird side effects my Dr did say to make sure I drank plenty of water especially being on HCTZ because it can cause depletion in water/potassium
I have never been on jardiance, but it looks like some common side effects include dehydration, yeast infections (both men and women), low blood sugar, kidney issues, allergic reactions, and UTI's.
Have you talked to your doctor about the side effects?
