Can metformin cause changes in mood? i have been crying nonstop everyday since starting it. should i be concerned?

Yes, : Yes,Metformin can cause issues with mood, although it’s not typically a common side effect. I have seen it with patients in my own practice. I recommend you talking to your physician about it, maybe they can adjust your medication or add something to help with mood. Also, exercise is the #1 treatment for depression in the world and I know it’s helpful for patients with diabetes. Good luck!
