I have atrial fibrillation. I take daily concor 10mg, dabigatran 220mg, Lasix 40mg and aldactone (spironolactone) 25mg, . Now I have erectile problem. What shall I do?

Talk to your doctor. Aldactone (spironolactone) and concor both could cause ed. Please review this with your doctor to find a better alternative. Do not stop medications by yourself.
Possible Aldactone (spironolactone) Aldactone (spironolactone) has testosterone blocking properties. Consider asking your doctor about a trial discontinuation for a period of time and see if that helps. Eplerenone may be an alternative if it makes a difference.
Ask your DR if . Prescription or herbal medicines for ed are safe for you. Best wishes! http://www.Mayoclinic.Com/health/erectile-dysfunction-herbs/mc00064 http://www.Mayoclinic.Com/health/erectile-dysfunction/ds00162/dsection=causes.
