Viagra: Everything You Need to Know About the World’s Most Popular Erectile Dysfunction Treatment

When it comes to searching for effective answers to erectile dysfunction (ED), the word Viagra is top of mind. But how much do you really know about this iconic blue pill, its benefits, side effects, and the safest ways to use it? Welcome to the most comprehensive, expert-driven Viagra resource on the web, built to answer your most pressing questions.

What Is Viagra? (Sildenafil Citrate Explained)

Originally developed by pharmaceutical giant Pfizer in 1998, Viagra (active ingredient: sildenafil citrate) revolutionized the treatment of male sexual dysfunction. Classified as a phosphodiesterase-5 (PDE5) inhibitor, Viagra enhances blood flow to the penis during sexual arousal, making it possible to achieve—and maintain—an erection suitable for intercourse. It’s a prescription medication approved by medical authorities like the U.S. Food & Drug Administration.

Other names for Viagra:

  • Sildenafil
  • Generic Viagra
  • Erectile Dysfunction Tablets
  • Blue Pill

How Does Viagra Work? (Mechanism of Action)

Viagra works by inhibiting an enzyme (PDE5) that restricts blood supply to the penis. By blocking this enzyme, the drug allows blood vessels to relax and expand, resulting in increased blood flow during sexual stimulation. Importantly, Viagra does not cause automatic arousal or erections—it works in response to sexual stimuli.

Dr. Emily Harper, Urologist:
“Viagra is highly effective for most men with ED, but it should be used under proper medical supervision. Always discuss your health history with your doctor before beginning treatment.”

Indications: Who Can Benefit From Viagra?

Viagra is primarily prescribed for men experiencing erectile dysfunction due to physiological or psychological causes. It is also occasionally used off-label for certain cases of pulmonary arterial hypertension (under the brand name Revatio).

  • Common candidates: Men aged 18-80 with trouble achieving or maintaining erections
  • Psychological ED: Stress, anxiety, or depression impacting performance
  • Physical causes: Diabetes, cardiovascular disease, nerve damage

Who Should NOT Use Viagra?

  • Those taking nitrates (heart medications) or nitric oxide donors
  • Severe cardiovascular disorders
  • Severe liver or kidney impairment
  • Known allergy to sildenafil

How to Use Viagra: Dosage and Instructions

Viagra is available in 25 mg, 50 mg, and 100 mg tablets. The typical starting dose is 50 mg, taken about 30-60 minutes before sexual activity (maximum once per day). Dosages may be adjusted depending on response and side effect profile.

25 mg 30-60 minutes before sex Elderly or those with liver/kidney issues
50 mg Standard starting dose Most men
100 mg 30-60 minutes before sex, if lower dose ineffective Consult doctor first

Pro Tip: Take Viagra on an empty stomach for best results; high-fat meals may delay absorption. Never mix with alcohol or recreational drugs.
