What Is Viagra? Mechanism, Indications & Origins

Viagra is the brand name for sildenafil citrate, a prescription medication approved by the FDA since 1998 for the treatment of erectile dysfunction (ED) in adult men. Viagra belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors. Other PDE5 inhibitors include tadalafil (Cialis) and vardenafil (Levitra).

How Does Viagra Work?

• Relaxation: It relaxes blood vessels in the penis.
• Increased Flow: More blood can flow in, resulting in an erection when you’re sexually aroused.
• No Spontaneous Erections: Viagra only works with sexual stimulation—it’s not a magical arousal pill.

How to Use Viagra – Dosages, Timing, Best Practices

Doctor’s Note: “Viagra should always be taken about 30–60 minutes before sexual activity. Food can slow its absorption—if rapid effect is desired, take on an empty stomach. Never exceed one dose per 24 hours.”
—Dr. Carl Renner, Board Certified Urologist

Tips for Safe Use

• Don’t mix with alcohol—this can reduce effectiveness and increase risk of side effects.
• Don’t use with other ED pills unless your doctor says so.
• Monitor for side effects. If you feel chest pain, dizziness, or a prolonged erection (>4 hours), seek medical help immediately.

• Rare but Serious: Priapism (painful, prolonged erection), sudden hearing loss, heart attack symptoms (chest pain, jaw pain, shortness of breath)
