Vilitra 20 is a medication that contains vardenafil, which is used to treat erectile dysfunction (ED). It works by increasing blood flow to the penis, helping to achieve and maintain an erection when sexually aroused. It’s generally taken about 30 to 60 minutes before sexual activity, and its effects can last for several hours. It’s essential to discuss your medical history with a healthcare provider, especially if you have heart issues or are taking medications like nitrates.
