I take 2000 mg of metformin daily. Because my A1C has started to rise, my doctor recently put me on glimepiride (brand name Amaryl). I have been on the glimepiride for about 2 weeks. Almost daily since I began the new medicine, I have had some dizziness or light-headedness that makes my head feel weird. Yesterday I did not take the glimepiride and I was much better and I did not take it again today and I was EVEN better. So, I think it is the glimepiride making my head feel like that. Has anyone experienced a side-effect like this on glimepiride? I need to talk to my doctor, but I would like to hear other people's experiences with it as well. Anyone?
