GSK Levitra: A Comprehensive Guide

Consult your doctor before starting Levitra. They can assess your health and determine the appropriate dosage for you. Levitra, manufactured by GSK (GlaxoSmithKline), contains vardenafil, a medication used to treat erectile dysfunction (ED).

Understanding Levitra’s Mechanism

Vardenafil works by increasing blood flow to the penis, facilitating an erection. It enhances the effects of nitric oxide, a naturally occurring substance crucial for penile erection. The medication is most effective when sexual stimulation is present.

Dosage and Administration

Levitra comes in various strengths (2.5mg, 5mg, 10mg, and 20mg). Your doctor will prescribe the right dose based on your individual needs and health status. It’s typically taken 25-60 minutes before sexual activity, and its effects can last for up to 4-5 hours. Never exceed the prescribed dosage.

Potential Side Effects

Like any medication, Levitra can cause side effects. Common ones include headache, flushing, nasal congestion, and indigestion. More serious, though rare, side effects may occur. Seek immediate medical attention if you experience sudden vision loss, hearing loss, or prolonged erection (priapism).
