I have right renal artery stenosis and a mechanical aortic valve replacement. l would like to know if Verelan ER / PM is safer to take than Verapamil ER? Thank you so much for a reply. ## They are both the same thing, the Veralan is just a name brand for Verapamil. Thus, as to safety and the risk of side effects, the possible issues would be identical. Have you discussed your concerns with your doctor?
