What is Viagra? Understanding the Gold Standard for Erectile Dysfunction
Originally developed in the 1990s and approved by the FDA in 1998 [FDA], Viagra, the brand name for sildenafil citrate, revolutionized the treatment of erectile dysfunction (ED). As the first medication in its class, Viagra enables millions of men to regain sexual confidence and improve quality of life.
- Generic Name: Sildenafil Citrate
- Brand Names: Viagra, Revatio (for pulmonary hypertension)
- Drug Class: Phosphodiesterase type 5 (PDE5) inhibitor
Quick Facts Table: Viagra and Sildenafil
| Aspect | Details |
|---|---|
| Primary Use | Erectile Dysfunction (ED), also Pulmonary Arterial Hypertension (as Revatio) |
| How It Works | Relaxes blood vessels in the penis, allowing for increased blood flow during sexual stimulation |
| Prescription Status | Prescription-only in most countries |
| Common Dosages | 25mg, 50mg, 100mg tablets; the usual starting dose is 50mg |
| Time to Effect | 30-60 minutes, remains effective for up to 4 hours |
| Most Common Side Effects | Headache, flushing, nasal congestion, upset stomach, dizziness |
Mechanism of Action: How Does Viagra (Sildenafil) Work in the Body?
Viagra relaxes the smooth muscle cells lining the blood vessels in the penis by inhibiting the PDE5 enzyme. This results in increased cyclic guanosine monophosphate (cGMP), leading to improved blood flow upon sexual stimulation [NIH]. Viagra does not cause an erection without sexual arousal—it enhances the body’s natural response to stimulation.
Who Should Use Viagra? Indications, Safety, and Appropriateness
Viagra is primarily prescribed for men diagnosed with erectile dysfunction. Doctors may also recommend sildenafil under other brand names for pulmonary arterial hypertension or Raynaud’s phenomenon. ED can result from medical, psychological, or lifestyle factors—so a doctor’s assessment is crucial.
Who May Benefit from Viagra?
- Men with persistent trouble achieving or maintaining an erection
- Patients experiencing ED due to diabetes, cardiovascular disease, or stress
- Some off-label uses under medical supervision (must be discussed with a healthcare provider)
Viagra is not intended for use in women or children.
How to Use Viagra Safely: Dosage, Timing, and Best Practices
Doctor Recommendations on Dosage and Use
Dr. Emily Thompson, a board-certified urologist, advises: “The ideal starting dose is usually 50mg, taken about an hour before planned sexual activity. Some men respond to 25mg, while others may need 100mg—dosing should always be tailored by your healthcare provider.”
- Dose timing: Take 30-60 minutes before intimacy
- Maximum dose: 100mg (do not exceed once daily)
- Food: High-fat meals may delay the drug’s onset and lower effectiveness
- Alcohol: Limit intake—alcohol can worsen side effects and reduce efficacy

Viagra Myths vs. Facts: Addressing Common Questions
- “Does Viagra increase libido?” No. Viagra improves the erectile response during sexual stimulation, but it does not boost desire.
- “Can I get addicted to Viagra?” No evidence supports physical addiction, though psychological dependence is possible if underlying causes of ED aren’t addressed.
- “Is it safe for recreational use?” Absolutely not—non-medical use increases risk of serious side effects, especially with alcohol or street drugs.
- “Will it work the first time?” For most men, yes. Factors such as anxiety, alcohol use, or improper dosing can reduce effectiveness.
Doctor’s Perspective: Ensuring Real, Lasting Sexual Health
Pharmacist Michael Braun, PharmD, notes: “Viagra is most effective when combined with lifestyle changes—exercise, weight management, and mental health all play a crucial role. ED can be the ‘canary in the coal mine’ for cardiovascular risk—don’t ignore warning signs.”
