Brand Viagra 100mg, containing sildenafil citrate, primarily helps men achieve and maintain erections. This benefit stems from improved blood flow to the penis. Many users report increased sexual satisfaction and improved confidence in their sexual performance.
Possible Side Effects
While generally well-tolerated, side effects can occur. These are usually mild and temporary. Common side effects include headaches, flushing, nasal congestion, and upset stomach. Less common, but more serious, side effects include vision changes (blurred vision, blue tint to vision), hearing loss, and prolonged erection (priapism). Seek immediate medical attention if a prolonged erection lasting more than four hours develops.
Dosage and Precautions
Always follow your doctor’s instructions regarding dosage. The recommended starting dose is usually 50mg, and it may be increased to 100mg or decreased based on your individual response and any side effects experienced. Viagra should not be taken with nitrates (certain heart medications) due to the risk of dangerously low blood pressure. Individuals with pre-existing heart conditions, liver problems, or kidney disease should discuss their suitability for Viagra with their physician before use.
