What It Is and How It Works
Viagra contains the active ingredient sildenafil, which is a type of medication known as a phosphodiesterase type 5 (PDE5) inhibitor. It works by relaxing blood vessels and increasing blood flow to the penis, helping to achieve and maintain an erection when sexually stimulated. This mechanism primarily supports symptom relief rather than treating underlying causes of erectile dysfunction.
Indications / Uses
Viagra is officially approved for the treatment of erectile dysfunction in men. While off-label uses exist, these should only be considered under professional medical guidance. Viagra is not appropriate for women or children.
Dosage Forms and Typical Dosing Considerations
Viagra is available as oral tablets in various doses, including 25 mg, 50 mg, 100 mg, and less commonly 200 mg. The 200 mg dose is quite high and should only be taken if specifically prescribed by a healthcare professional. Factors such as age, underlying health conditions, and concurrent use of other medications can influence the appropriate dosage.
How to Take It Correctly Step-by-Step
Viagra should be taken as prescribed, usually one hour before sexual activity. It can be taken with or without food, though it may work more slowly after a high-fat meal. Consistency with timing and following the prescription label are important. Avoid taking more than the recommended dose and do not double up if a dose is missed. Store in a cool, dry place away from direct sunlight.
Side Effects Common to Serious
Common Side Effects
Include headaches, flushing, upset stomach, and nasal congestion.

Serious Side Effects

Contraindications & Precautions
Viagra should not be used by individuals with severe heart or liver problems, recent history of stroke or heart attack, or low blood pressure. It is contraindicated in those taking nitrates or nitric oxide donors. Pregnant or breastfeeding women should avoid use due to lack of safety data. Elderly or renal-impaired individuals must consult a healthcare provider for dose adjustment.
Drug, Food, and Supplement Interactions
