What is Viagra? An In-Depth Look at the Popular ED Medication

Introduction to Viagra

Viagra, scientifically known as sildenafil, is a widely recognized medication used primarily to treat erectile dysfunction (ED) in men. It functions by increasing blood flow to the penis, helping men achieve and maintain an erection. Approved by the FDA in 1998, Viagra has since transformed the landscape of ED treatments. For those seeking reliable options, our site offers a convenient way to purchase Viagra.

Mechanism of Action

Viagra falls under the class of drugs known as phosphodiesterase type 5 (PDE5) inhibitors. By blocking the PDE5 enzyme, Viagra enhances the effects of nitric oxide, a natural chemical the body produces to relax muscles in the penis. This relaxation increases blood flow, enabling an erection in response to sexual stimulation. This mechanism is why Viagra is effective for many men experiencing ED.

Indications for Use

• Treatment of erectile dysfunction
• Occasionally prescribed for pulmonary arterial hypertension under a different brand name, Revatio

Before starting Viagra, it is vital to consult a healthcare provider to ensure it is appropriate for your condition and to discuss any potential interactions with other medications.

How to Use Viagra

Viagra is typically taken orally, about 30 minutes to an hour before sexual activity. It is important to follow the healthcare provider’s instructions regarding dosage and timing. While it can be taken with or without food, a high-fat meal might delay its effect. Do not take more than one dose in a 24-hour period.

Recommended Dosages

The standard starting dose for Viagra is 50 mg, but this can be adjusted to 25 mg or 100 mg depending on efficacy and tolerability. Factors such as age, overall health, and other medications can influence the optimal dose. Always adhere to the prescribed dosage and consult a healthcare provider for adjustments.

Possible Side Effects

While Viagra is generally well-tolerated, some users may experience side effects. Common side effects include:

• Headache
• Flushing
• Upset stomach
• Abnormal vision, such as changes in color vision
• Stuffy or runny nose
• Back pain

More serious side effects, although rare, require immediate medical attention:

• Sudden vision loss
• Sudden hearing decrease or loss
• Chest pain or irregular heartbeat
• Prolonged erection lasting more than four hours
