Vilitra 40 is a medication used to treat erectile dysfunction (ED) in men. It contains vardenafil as its active ingredient, which is a phosphodiesterase type 5 (PDE-5) inhibitor. Vardenafil works by increasing blood flow to the penis during sexual stimulation, facilitating an erection. Inform your healthcare provider about your medical history, especially if you have any heart problems, high or low blood pressure, liver or kidney disease, or other health conditions. Avoid using Vilitra 40 with nitrates or certain other medications, as interactions can occur.
