What It Is and How It Works
Viagra contains the active ingredient sildenafil citrate, which belongs to a class of medications known as phosphodiesterase type 5 (PDE5) inhibitors. It functions by inhibiting the PDE5 enzyme, resulting in increased levels of cyclic guanosine monophosphate (cGMP). This biochemical process promotes the dilation of blood vessels in the penis, improving blood flow during sexual arousal, which helps achieve and maintain an erection.
Indications / Uses
Viagra is primarily indicated for the treatment of erectile dysfunction in adult men. It helps those who experience difficulty maintaining an erection sufficient for sexual activity. Though Viagra is generally not prescribed for other conditions, some clinicians might consider it off-label for pulmonary arterial hypertension, albeit at different dosages and under close medical supervision.
Dosage Forms and Typical Dosing Considerations
Viagra is available in 25 mg, 50 mg, and 100 mg oral tablets. The typical starting dose is often 50 mg taken about one hour before sexual activity. Dosage may be adjusted based on individual response and tolerability. Usage of 200 mg is not standard and requires thorough evaluation as this higher dosage significantly increases the risk of side effects. Kidney and liver function, age, and concurrent medical conditions greatly influence dosing decisions.
How to Take It Correctly Step-by-Step
- Take Viagra approximately 30 to 60 minutes before planned sexual activity.
- Swallow the tablet whole with water, with or without food. However, a high-fat meal may delay its effect.
- Do not exceed one dose per day.
- If a dose is missed, skip that day’s dosage and take only the advised amount next time.
- Store the medication at room temperature away from excessive heat and moisture.
- Avoid alcohol and grapefruit products, which may interfere with effectiveness and increase side effect risks.
