What is Viagra? Understanding the Basics
Viagra is the brand name for sildenafil citrate, a prescription medication that revolutionized the treatment of erectile dysfunction. Approved by the FDA in 1998, Viagra quickly became the leading oral therapy for men experiencing difficulties in achieving or maintaining an erection.
- Drug Class: Phosphodiesterase type 5 (PDE5) inhibitor
- Indications: Erectile dysfunction, sometimes prescribed for pulmonary arterial hypertension
- Prescription Status: Prescription-only in most countries
How Does Viagra Work? (Mechanism of Action Explained)
When sexual stimulation occurs, nitric oxide is released in the penis. This stimulates the production of cGMP, which causes smooth muscle relaxation and increased blood flow. Viagra works by blocking an enzyme called PDE5 (phosphodiesterase type 5). By inhibiting this enzyme, Viagra helps maintain higher levels of cGMP, resulting in improved, natural erections in response to sexual stimulation.

How to Use Viagra: Dosage, Timing, and Tips for Best Results
Always consult your healthcare provider before starting Viagra. Here’s what you need to know for safe and effective use:
| Recommended Starting Dose | 50 mg (one hour before sexual activity) |
|---|---|
| Can Be Adjusted To | 25 mg (if side effects occur) or 100 mg (if higher efficacy is needed and tolerated) |
| Maximum Frequency | Once per day |
| Food Considerations | High-fat meals may delay absorption |
| Alcohol | Limit intake, as it can increase side effects |
- Take Viagra with a full glass of water
- Do not take with other PDE5 inhibitors (e.g., Cialis, Levitra)
- Communicate openly with your partner for best outcomes

Viagra is suitable for men over 18 who experience ED, but it’s NOT for everyone. Contraindications include:
- Concurrent nitrate medication use (e.g., nitroglycerin)

- Uncontrolled hypertension or low blood pressure
- Known allergy to sildenafil or similar compounds
Always discuss your health history with a licensed medical provider.

- Headache

- Nasal congestion
- Indigestion
- Visual changes (blue-tinted vision)
Rare but serious side effects include priapism (an erection lasting longer than 4 hours), sudden vision or hearing loss, and allergic reactions. If you experience chest pain or severe side effects, seek immediate medical attention.
