The crap almost killed my nephew.
NMobody even knew he was taking it until he suddenly began to gain weight, became a head case, and lost all energy. Finally passed out while driving.
Have never heard of weight GAIN with metformin. That must be one of the more unusual side effects.
Usually it’s a weight loss drug. If only because you stay in the potty...
“”Finally passed out while driving.”
I had “light-headed” problems too. Finally went back to the doc after almost passing out driving.
My husband was on metformin for about ten yrs when his doctor took him off of it because “in medical school we had a patient to die from it”. Apparently you build up a saturation of the drug. He got off of it and got Alzheimer’s.
