Generic Viagra is a cost-effective alternative to the brand-name Viagra, used to treat erectile dysfunction (ED) in men. It contains sildenafil citrate as the active ingredient, which works by increasing blood flow to the penis, helping to achieve and maintain an erection during sexual activity. Generic Viagra offers the same effectiveness as the brand-name version but at a lower price, making it an affordable option for many. It is available in various dosages and should be taken as prescribed by a healthcare provider to ensure safety and optimal results.
