Filitra 40 mg is a medication used to treat erectile dysfunction (ED) in men. It contains vardenafil, a PDE5 inhibitor, which works by relaxing the muscles in the blood vessels of the pill, increasing blood flow to help achieve and maintain an erection during physical arousal. Common side effects include headaches, dizziness, flushing, nasal congestion, and indigestion. In rare cases, more serious side effects like sudden vision or hearing loss may occur. If these happen, seek medical attention immediately.
