Zhewitra 20 is a medication used to treat erectile dysfunction (ED) in men. The active ingredient in Zhewitra 20 is Vardenafil, which belongs to a class of drugs called phosphodiesterase type 5 inhibitors (PDE5 inhibitors).

Vardenafil works by increasing blood flow to the penis, which helps to achieve and maintain an erection during physical stimulation. Zhewitra 20 is available in tablet form and is usually taken orally about 30 minutes before physical activity.

Like all medications, Zhewitra 20 may cause side effects such as headache, flushing, stuffy or runny nose, indigestion, and back pain. It should not be taken by individuals who are taking nitrates or guanylate cyclase stimulators, as this can cause a severe drop in blood pressure.

It is important to consult with a healthcare professional before taking Zhewitra 20, as it may interact with other medications or have contraindications with certain health conditions.
