Well, I am not a doctor, but I have been taking the same meds and Metformin for 6 years with no probs. I have not had any side effects or interaction between the drugs. In fact I take two others as well, Bisoprolol and Simvastatin. That's seven pills by my count, plus Vitamin B complex and Chromium.
ask your doctor but I was told that blood pressure drugs and metformin do not interact by the chemist I get my tablets from. You have to believe someone sometime.
HI. I'm prescribed Metformin and Ramipril so they are OK together. I'm not aware of any issues with aspirin and Met. Can't comment on the other druga but check with your pharmacist if in any doubt.
