Vilitra is a medication commonly prescribed to treat erectile dysfunction (ED) in men. It contains vardenafil, a phosphodiesterase type 5 (PDE5) inhibitor, which works by relaxing the blood vessels in the penis, increasing blood flow during sexual arousal to help achieve and maintain an erection. Common side effects include headache, flushing, nasal congestion, dizziness, and upset stomach. While generally safe, serious side effects such as sudden vision or hearing loss, or prolonged erections, require immediate medical attention. https://www.genericday.com/vilitra.html
