Hello, metoprolol is a beta-blocker drug. Beta-blocker drugs have shown efficacy in reducing death rates after myocardial events. So taking a beta-blocker is essential and cannot be avoided. Unfortunately they do have some side-effects like the erection problem you ve mentioned. Perhaps your doctor could try another beta-blocker instead of metoprolol but be informed that all beta-blockers cause erection problems. Perhaps a dosage change could be tried as well, but you ll have to talk with your treating cardiologist for that. So in conclusion I wouldn t recommend replacing this drug category but you can try (with your cardiologist s consent) another drug or try a dose reduction, to see what happens. I hope I ve helped! If you d like further information about this drug, you can contact me again and I ll be glad to help. Kind Regards!
