Fildena 100mg does not cure erectile dysfunction (ED) permanently. The active ingredient, sildenafil citrate, works by increasing blood flow to the penis, but its effects last only for a few hours. While Fildena 100mg is effective in managing ED symptoms, it does not address the root causes such as stress, anxiety, or underlying health issues. A permanent solution may require lifestyle changes, therapy, or treatment of medical conditions. Always consult a doctor to determine the best approach for long-term ED management.
