## Introduction to Viagra

Viagra, known generically as sildenafil, is a medication primarily used to treat erectile dysfunction (ED) in men. Originally developed by Pfizer, it has become a cornerstone in the treatment of sexual health issues. This article delves into Viagra’s mechanism of action, indications, side effects, and recommended usage.

## What is Viagra?

### H1: Viagra – A Solution for Erectile Dysfunction

Viagra is a prescription medication that helps men achieve and maintain an erection sufficient for sexual intercourse. It works by increasing blood flow to the penis, making it easier to get and maintain an erection when sexually aroused.

### H2: How Does Viagra Work?

Viagra is classified as a phosphodiesterase type 5 (PDE5) inhibitor. It functions by blocking the enzyme PDE5, which results in the relaxation of blood vessels and improved blood flow to the penis. This physiological response is crucial in facilitating an erection during sexual stimulation.

### H3: Indications for Use

Viagra is primarily prescribed for:

– Erectile Dysfunction (ED): The inability to achieve or maintain an erection suitable for sexual intercourse.
– Pulmonary Arterial Hypertension (PAH): Although less common, Viagra can be used to treat PAH by relaxing the blood vessels in the lungs, improving exercise capacity.

## Dosage and Administration

### Recommended Dosages

Viagra is available in several dosages: 25 mg, 50 mg, and 100 mg. The standard starting dose is 50 mg, taken as needed approximately one hour before sexual activity. Depending on efficacy and tolerability, the dose may be adjusted.

### How to Use Viagra Safely

– Timing: Take Viagra about 30 to 60 minutes before sexual activity. Its effects can last up to four hours, but this does not mean you will have an erection for the entire duration.
– Food Interactions: High-fat meals can delay the drug’s effect. It’s best to take Viagra on an empty stomach or with a light meal.
– Alcohol: Limit alcohol consumption as it can reduce the effectiveness of the medication.

### H2: Potential Side Effects

While Viagra is generally safe, it may cause side effects in some individuals. Common side effects include:

– Headaches
– Flushing
– Indigestion
– Nasal congestion
– Dizziness

Less common but serious side effects require immediate medical attention and include:

– Sudden vision loss
– Hearing loss
– Priapism (a prolonged erection lasting more than four hours)
