Zhewitra 10 mg contains vardenafil, which is a medication primarily used to treat erectile dysfunction (ED) in men. Vardenafil works by increasing blood flow to the penis, helping men achieve and maintain an erection during sexual activity. The recommended dosage of Zhewitra (vardenafil) can vary depending on individual factors such as age, overall health, and the severity of erectile dysfunction. Typically, the starting dose for most men is 10 mg taken orally as needed, about 30 minutes to 1 hour before sexual activity. The dosage can be adjusted based on effectiveness and tolerability, with a maximum recommended dose of 20 mg per day.
