Understanding Viagra: Uses, Dosage, and Side Effects
What is Viagra?
Viagra, known generically as sildenafil, is a medication prescribed for the treatment of erectile dysfunction (ED) in men. It was developed by Pfizer and received FDA approval in 1998. Viagra works by increasing blood flow to the penis, helping men achieve and maintain an erection.
How Does Viagra Work?
Viagra belongs to a class of drugs known as phosphodiesterase type 5 (PDE5) inhibitors. It functions by blocking the enzyme PDE5, which results in the relaxation of smooth muscle cells and dilation of blood vessels in the penis. This action enhances blood flow, facilitating an erection when combined with sexual stimulation.
Indications for Use
Viagra is primarily prescribed for erectile dysfunction, a condition where a man is unable to achieve or sustain an erection sufficient for sexual intercourse. It is not intended for use in women or children, and should only be used under the guidance of a healthcare provider.
How to Use Viagra
- Take Viagra orally, with or without food, about 30 minutes to 1 hour before sexual activity.
- Do not take more than one dose within a 24-hour period.
- Follow your healthcare provider’s instructions regarding dosage and frequency.
Recommended Dosage
| Condition | Initial Dose | Maximum Dose | Frequency |
|---|---|---|---|
| Erectile Dysfunction | 50 mg | 100 mg | Once daily |
Dosage may vary based on individual health conditions and response to treatment. Always consult a healthcare professional before adjusting your dose.
Potential Side Effects
While Viagra is generally safe, it can cause side effects in some individuals. Common side effects include:
- Headache

If you experience severe side effects such as chest pain, an erection lasting more than four hours, or sudden vision loss, seek medical attention immediately.
