Viagra: Everything You Need to Know
Welcome to our comprehensive guide on Viagra, the medication that has revolutionized the treatment of erectile dysfunction. Whether you’re considering using Viagra or simply want to learn more about it, this article will cover everything from how it works to tips on purchasing it safely.
What is Viagra?
Viagra, known generically as sildenafil citrate, is a medication primarily used to treat erectile dysfunction (ED) in men. It was first approved by the U.S. Food and Drug Administration (FDA) in 1998 and has since become one of the most popular and widely prescribed treatments for ED.
How Does Viagra Work?
Viagra works by increasing blood flow to the penis, helping to achieve and maintain an erection when sexually aroused. It belongs to a class of drugs known as phosphodiesterase type 5 (PDE5) inhibitors. Viagra inhibits the PDE5 enzyme, which leads to increased levels of cyclic guanosine monophosphate (cGMP), causing relaxation of the smooth muscles and dilation of blood vessels in the penis.
Indications for Use
- Treatment of erectile dysfunction in adult men
- Prescribed off-label for pulmonary arterial hypertension (under the name Revatio)
Always consult with a healthcare provider to determine if Viagra is suitable for your condition and to obtain a prescription.
Viagra Dosage Recommendations
The typical starting dose for Viagra is 50 mg taken as needed, about one hour before sexual activity. However, it can be taken anywhere from 30 minutes to 4 hours before intercourse. Depending on efficacy and tolerability, the dose may be increased to a maximum recommended dose of 100 mg or decreased to 25 mg.
| Dosage | Effectiveness Timeframe |
|---|---|
| 25 mg | Between 30 minutes to 4 hours |
| 50 mg | Between 30 minutes to 4 hours |
| 100 mg | Between 30 minutes to 4 hours |
Potential Side Effects
Like all medications, Viagra can cause side effects. Common side effects include:
- Headache
- Flushing
- Upset stomach
- Nasal congestion
- Vision changes such as increased sensitivity to light or blurred vision
If you experience serious side effects such as chest pain, severe dizziness, or an erection lasting more than four hours (priapism), seek medical attention immediately.
