What It Is and How It Works

Viagra is a medication that belongs to a class of drugs known as phosphodiesterase type 5 (PDE5) inhibitors. It works by blocking the enzyme PDE5, which results in the relaxation of smooth muscle and increased blood flow to the penis, enabling an erection in response to sexual stimulation. This mechanism specifically targets the physiological processes that underpin erectile dysfunction.

Indications / Uses

Viagra is primarily indicated for the treatment of erectile dysfunction, a condition characterized by the inability to achieve or maintain an erection sufficient for satisfactory sexual performance. While it is not a cure for ED, it can help manage the symptoms. Viagra may also be used off-label for other conditions like pulmonary arterial hypertension, but these uses should be guided by a healthcare professional.

Dosage Forms and Typical Dosing Considerations

Viagra is available in several dosage forms: 25 mg, 50 mg, and 100 mg oral tablets. A 200 mg dose is often considered too high and not standardly approved, thus requiring careful discussion with a healthcare provider. Dosage may vary based on factors such as age, severity of ED, concurrent medications, and overall health. Elderly or patients with kidney/liver dysfunction may require dose adjustments.

How to Take It Correctly Step-by-Step

Take Viagra about 30 to 60 minutes before sexual activity.
The medication can be taken with or without food; however, a high-fat meal might delay its onset of action.
