Pay careful attention to patients who are being treated for ED with one of the PDE5 inhibitors because most are already at a higher risk of developing a vascular event secondary to age. If nothing else, when a patient presents with signs and symptoms of NAION, a complete review of medications, including specific questions regarding sildenafil usage, is imperative. Inform your patients about the potential risks of sildenafil.

These medicines prevent an enzyme called phosphodiesterase type-5 from working too quickly. The penis is one of the areas where this enzyme works. Erectile dysfunction is a condition where the penis does not harden and expand when a man is sexually excited, or when he cannot keep an erection. When a man is sexually stimulated, his body's normal response is to increase blood flow to his penis to produce an erection. By controlling the enzyme, sildenafil helps to maintain an erection after the penis is stroked. Without physical action to the penis, such as that occurring during sexual intercourse, sildenafil will not work to cause an erection.
