Vilitra 20 mg is a prescription medication for erectile dysfunction (ED) containing vardenafil, a phosphodiesterase‑5 (PDE5) inhibitor that helps adult men improve erections during sexual stimulation. It works by increasing blood flow to the penis when arousal occurs, making it easier to achieve and maintain a firm erection. A single dose is usually taken about 30–60 minutes before sexual activity, and the effects can last approximately 4–6 hours.
