Vilitra is a prescription medication used to treat erectile dysfunction (ED) in adult men. Its active ingredient is Vardenafil, which belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors. Vardenafil works by relaxing the blood vessels in the penis, increasing blood flow during sexual stimulation, which helps men achieve and maintain an erection. Sexual arousal is required for the medication to be effective. Common side effects include headache, flushing, dizziness, nasal congestion, and upset stomach. Rare but serious side effects include prolonged erections (priapism), sudden vision or hearing loss, or severe allergic reactions, which require immediate medical attention.
