Zhewitra 20 mg is a prescription medication for men experiencing erectile dysfunction (ED). It contains Vardenafil, a clinically approved PDE5 inhibitor. By enhancing blood flow to the penis during sexual arousal, it helps men achieve and maintain a firm and lasting erection. For a detailed medical overview of ED treatments, you can visit Mayo Clinic.

How Zhewitra 20 mg Works

Vardenafil works by blocking the PDE5 enzyme, which increases cyclic guanosine monophosphate (cGMP) levels. Higher cGMP levels relax smooth muscles in penile blood vessels, allowing improved circulation and supporting stronger erections during sexual stimulation. More insights on this mechanism are available on PubMed and Healthline.

Dosage & Administration

• Take one tablet 30–60 minutes before sexual activity.

• It may be taken with or without food, but a high-fat meal may delay its effect.

• Do not take more than one tablet in 24 hours.
