Hello there, I can understand your concern. The medication you are on for diabetes seems to be correct but to validate whether it is enough for you or not I need to know how well you are controlled with these medications. Fasting blood sugars and Post meal blood sugars and HbA1c values will determine this. Now to answer your question, uncontrolled diabetes and high blood sugars can cause ED issues and not any of these medicines. Your age also affects this issue and it would have helped to know your age. Having ED issues also could mean a high risk for heart issues and so you need to be evaluated thoroughly for the cause of ED. You should visit a diabetologist who can evaluate you and suggest blood tests like FBS,PPBS, HbA1c, Kidney functions, Lipid profile, Liver function, and guide you further for treatment. Till then continue to take your medications correctly and also diet and exercise play a major role in blood sugar control. Hope this helps. Take care.
