Zhewitra is a brand name for a medication containing vardenafil, which is primarily used to treat erectile dysfunction (ED) in men. Vardenafil is a phosphodiesterase type 5 (PDE5) inhibitor, similar to sildenafil (Viagra), tadalafil (Cialis), and avanafil (Stendra). Zhewitra works by increasing blood flow to the penis during sexual stimulation, which helps men achieve and maintain an erection. It is typically taken orally, as needed, prior to sexual activity. Zhewitra is available in various strengths, including 20 mg, 40 mg, and 60 mg tablets. https://www.flatmeds.com/product/zhewitra-20-mg/
