Fildena 100 mg, which contains sildenafil citrate, is used to treat erectile dysfunction. While generally effective, long-term use can carry risks. Chronic use may lead to psychological dependence, where users feel they can't perform without it. Cardiovascular risks exist, especially in individuals with preexisting heart conditions, as sildenafil affects blood pressure and heart workload. Other potential long-term effects include vision changes (such as blue-tinted vision or blurred vision), hearing loss, and priapism (prolonged, painful erections). Some users report gastrointestinal issues and headaches over time. Interactions with nitrate-containing medications can be dangerous. Always consult a healthcare provider for safe, long-term use.
