answer

Viagra (sildenafil), Cialis (tadalafil), or Levitra (vardenafil) are not safe to take if you have low blood pressure. In addition, taking drugs for erectile dysfunction (ED) along with alpha blockers like doxazosin mesylate (Cardura), prazosin hydrochloride (Minipress), and terazosin (Hytrin) to lower high blood pressure -- or with nitroglycerin and other nitrate-based drugs (for example, Isordil, Monoket, and Nitrostat) -- can cause a sudden, unsafe decrease in blood pressure.

If you have low blood pressure, or are taking an alpha blocker or a nitrate-based drug, talk to your doctor about ED treatment that is right for you.
