Viagra is a prescription medicine containing sildenafil, a phosphodiesterase type 5 (PDE5) inhibitor. It is primarily used to treat erectile dysfunction (ED) in adult men. Sildenafil works by increasing blood flow to the penis during sexual stimulation, helping achieve and maintain an erection. It does not increase sexual desire and does not cause an erection without sexual stimulation. Understanding Viagra uses, Viagra benefits, Viagra side effects, and Viagra precautions is important before treatment.

Uses

Viagra may be prescribed for:

• Erectile dysfunction in adult men
• Difficulty achieving or maintaining an erection sufficient for sexual activity

Benefits

Potential Viagra benefits include:

• Helps improve the ability to achieve an erection
• May help maintain an erection during sexual activity
• Can improve erectile function in men with ED
• May improve sexual satisfaction when ED is appropriately treated

Sexual stimulation is required for sildenafil to produce an erection.

Side Effects

Viagra side effects may include:

• Headache
• Flushing
• Indigestion
• Nasal congestion
• Dizziness
• Visual changes

Serious effects requiring immediate medical attention include chest pain, severe allergic reactions, sudden loss of vision or hearing, or an erection lasting longer than four hours. These conditions require urgent medical evaluation.

Interactions

Important Viagra precautions include informing your healthcare provider about all medicines and supplements you use. Sildenafil can interact with:

• Nitrate medicines, which can cause a dangerous drop in blood pressure
• Alpha-blockers and other blood-pressure-lowering medicines
• Certain antifungal, antibiotic, and HIV medicines that affect sildenafil metabolism
• Other medicines used to treat erectile dysfunction
• Alcohol, particularly in large amounts, which may increase dizziness or low blood pressure
• Herbal sexual-enhancement products with undisclosed ingredients
• Medical conditions such as serious heart disease, low blood pressure, certain eye disorders, or recent cardiovascular events

Do not use Viagra with nitrate medicines or combine it with other ED treatments without professional medical advice.
