Filitra 20 mg does not increase sexual desire and does not work without sexual arousal. It is typically taken orally about 30 to 60 minutes before planned sexual activity. The effect generally lasts for around 4 to 6 hours, although this can vary depending on age, metabolism, diet, and overall health. This dose is commonly prescribed as a standard strength for men who require effective treatment for moderate erectile dysfunction. A healthcare provider determines the appropriate dosage based on individual response, tolerance, and medical history.
