Fildena 120 mg is a high-strength medication containing sildenafil citrate, commonly prescribed for erectile dysfunction (ED). Its primary role is to improve blood flow to the penis by relaxing blood vessels, which helps men achieve and maintain erections during sexual activity. While some users may describe the experience as feeling more energetic or lasting longer in bed, Fildena 120mg itself does not directly increase physical stamina or endurance in the way that exercise or lifestyle changes would. Instead, it may indirectly improve stamina in sexual performance by reducing anxiety, improving confidence, and allowing for more satisfying intimacy. However, it is not designed as a stamina booster or general performance enhancer. Men with underlying fatigue or low energy should consult a doctor to explore other possible causes, such as low testosterone, stress, or chronic medical conditions, rather than relying solely on ED medication for stamina improvement.
