Vilitra 20 mg is a medication used to treat erectile dysfunction (ED) in men. It contains Vardenafil, a PDE-5 inhibitor that improves blood flow to the penis, facilitating a strong and sustained erection when sexually aroused. Taken 30-60 minutes before sexual activity, its effects can last up to 5 hours. Common side effects include headache, flushing, nasal congestion, or dizziness. It is not an aphrodisiac and requires sexual stimulation to work. Consult a doctor before use, especially if you have heart conditions, low blood pressure, or are taking nitrates. Avoid alcohol and grapefruit for optimal results.
