Viagra, known generically as sildenafil, is a medication primarily used to treat erectile dysfunction (ED) in men. It works by increasing blood flow to the penis, helping to achieve and maintain an erection when sexually stimulated. However, understanding the correct dosage is crucial for effectiveness and safety.
