Zhewitra 20 mg is a medication used for the treatment of erectile dysfunction (ED) in men. It contains vardenafil hydrochloride, which belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors. Vardenafil works by increasing blood flow to the penis during sexual stimulation, thus helping to achieve and maintain an erection. It's typically taken orally about 25 to 60 minutes before sexual activity, and its effects can last for up to 4 to 5 hours. Always consult with a doctor before starting or changing any medication regimen. https://www.flatmeds.com/product/zhewitra-20-mg/
