Viagra (sildenafil) works by inhibiting the chemical phosphodiesterase, which leads to an increase in the effect of nitric oxide. Nitric oxide allows the smooth muscles inside the penis to relax, promoting more blood flow to the area during sexual arousal or stimulation. Nitric oxide also opens the blood vessels throughout the body, which can cause decreased blood pressure. This decrease in blood pressure may increase the effects of blood-pressure lowering drugs, especially alpha-blockers, such as terazosin (Hytrin), doxazosin (Cardura), and prazosin (Minipress). Patients with cardiovascular disease could have additional side effects from Viagra, especially in combination with sexual activity. Other common side effects of Viagra include warmth or redness in your face, neck, or chest; stuffy nose; headache; upset stomach; and back pain. More serious, but less frequent side effects include prolonged erection lasting more than 4 hours, vision changes, and loss of hearing. If these occur, you should contact your health care provider. Severe adverse events potentially related to blood-pressure effects were assessed. In the study (N=72 subjects), 2 such events were reported following administration of tadalafil (symptomatic hypotension in one subject that began 10 hours after dosing and lasted approximately 1 hour, and dizziness in another subject that began 11 hours after dosing and lasted 2 minutes). No such events were reported following placebo. In the period prior to tadalafil dosing, one severe event (dizziness) was reported in a subject during the doxazosin run-in phase. viagra prescription cost KwikMed is HIPAA compliant.
