Zhewitra 20 mg is marketed as containing vardenafil, a phosphodiesterase type 5 (PDE5) inhibitor used to treat erectile dysfunction (ED) in adult men. Vardenafil works by increasing blood flow to the penis during sexual stimulation, helping achieve and maintain an erection. Vardenafil does not increase sexual desire and does not normally produce an erection without sexual stimulation. For many adults, 10 mg is a commonly recommended starting dose, while 20 mg is generally the maximum recommended dose taken once in a 24-hour period.
