Fildena 150 mg is effective for treating erectile dysfunction (ED) because it contains a high dose of Sildenafil Citrate, a well-known and clinically proven medication for improving blood flow to the penis. It works by targeting the physiological causes of ED, helping men achieve and maintain a firm erection during sexual activity. Fildena 150 mg is effective only when there is sexual stimulation, as the medication enhances the body’s natural response to arousal. Without arousal, it will not cause an erection, which helps prevent unwanted effects and makes it more controlled in action. Fildena 150 mg is effective because of its strong dose of Sildenafil, reliable mechanism of action, and ability to significantly improve blood flow to the penis during arousal.
