Generic Viagra (sildenafil) is prescribed to treat erectile dysfunction (ED), the inability to get or maintain an erection, as a result of impotence. ED is common in men, characterized by complete or intermittent inability to get and maintain an erection for sexual activity. Viagra is not for use by women or children.

Viagra Prescription

Generic Viagra requires a prescription. You can get a prescription for generic Viagra (sildenafil) at Blink Health, including online doctor visit and refills. All generic medications sold through Blink Health Pharmacy are FDA-approved.

How Viagra works

Viagra is a phosphodiesterase 5 (PDE5) inhibitor, increasing blood flow to the penis during sexual stimulation to help achieve erection. Viagra does not cure ED, increase sexual desire, prevent pregnancy, or protect against sexually transmitted diseases (including HIV).

Viagra is most effective if taken 1 hour before sexual activity, but can be taken up to 4 hours prior. Do not take more than one dose every 24 hours. People with certain health conditions may need to limit Viagra doses; discuss with your doctor how often to take it.

Viagra vs Sildenafil

Viagra and sildenafil are medically the same, containing the same active ingredient sildenafil. The main difference is price where generic sildenafil is cheaper than branded Viagra (sold by Pfizer). Also, sildenafil is available in 20mg dosage. Viagra comes in diamond shaped blue pills and sildenafil comes in white or blue tablets. Both are equally effective for the treatment of erectile dysfunction.
