Fildena, containing the active ingredient Sildenafil, is primarily used to treat erectile dysfunction (ED) in men. Sildenafil, a phosphodiesterase type 5 (PDE5) inhibitor, works by enhancing blood flow to the penis during sexual stimulation. It does this by relaxing the blood vessels in the penile area, allowing for increased blood circulation, which helps men achieve and maintain a firm erection. Fildena is available in various dosages, making it possible to tailor treatment based on the severity of ED and individual response to the medication. Typically, Fildena 100mg is taken about 30-60 minutes before planned sexual activity, and its effects can last for up to 4-6 hours. This makes it a reliable option for men seeking to improve their sexual performance and regain confidence. While Fildena is effective for many, it is important to use it under the guidance of a healthcare provider to ensure safe usage, as potential side effects can include headaches, dizziness, flushing, and in rare cases, a prolonged erection (priapism), which requires immediate medical attention.
