Vilitra 20 mg is a stronger dose typically prescribed when the 10 mg dose is insufficient. It should be taken about 30 to 60 minutes before sexual activity, and its effects can last up to 4 to 6 hours, allowing for improved sexual performance and spontaneity. For best results, it is recommended to take Vilitra on an empty stomach or avoid heavy, fatty meals before use, as food can delay its onset. Common side effects include headache, flushing, nasal congestion, dizziness, and upset stomach, which are usually mild and temporary.
