What It Is and How It Works
Viagra is part of a class of drugs known as phosphodiesterase type 5 (PDE5) inhibitors. It works by blocking the PDE5 enzyme in the penis. This action helps to relax blood vessels and improve blood flow, making it easier to achieve an erection in response to sexual stimulation. Unlike some treatments for sexual dysfunction, Viagra does not directly cause an erection without sexual arousal.
Indications / Uses
The primary approved use of Viagra is for treating erectile dysfunction, a condition where a man cannot achieve or maintain an erection sufficient for satisfactory sexual performance. While Viagra is mainly prescribed for ED, it is occasionally used off-label for other circulatory problems as determined by a healthcare professional. It is important that off-label use be supervised by a healthcare provider.
Dosage Forms and Typical Dosing Considerations
Viagra is commonly available in tablet form, with strengths typically including 25 mg, 50 mg, and 100 mg. A 200 mg dosage is not standard and could potentially increase the risk of side effects. Dosages should always be determined by a healthcare provider, considering factors such as age, overall health, and concurrent medical conditions. Kidney and liver functions, as well as interactions with other medications, may also influence dosing decisions.
How to Take It Correctly Step-by-Step
Viagra should be taken as prescribed by a healthcare professional. Here are some general guidelines:
- Take Viagra about 30 to 60 minutes before planned sexual activity. It can be taken up to 4 hours before intercourse.
- Swallow the tablet whole with water.
- It can be taken with or without food, but high-fat meals may delay its action.
- Avoid consuming grapefruit or grapefruit juice, as it can increase the risk of side effects.
- If a dose is missed or if uncertain about proper use, consult your healthcare provider. Do not double the dose.
- Store tablets at room temperature away from moisture and heat.

Contraindications & Precautions

It is also not recommended for people with severe cardiovascular conditions, severe liver impairment, or those who have experienced a stroke or heart attack recently. Use with caution in older adults and those with kidney disease, retinitis pigmentosa, or anatomical deformation of the penis. Women, particularly those who are pregnant or breastfeeding, and children should not use Viagra.
Drug, Food, and Supplement Interactions
Viagra may interact with several other medications including:
- Nitrates (used for heart conditions) – can cause dangerous drops in blood pressure.
- Alpha-blockers (used for high blood pressure or prostate problems) – may lead to hypotension.
- Certain antifungals and antibiotics can increase the concentration of Viagra in the blood, enhancing its effects and side effects.
- Grapefruit products can amplify side effects.
Patients should inform their healthcare provider about all medications, supplements, and vitamins they are taking.
