It contains two active ingredients: Vardenafil (which is the primary ingredient in Levitra) and Dapoxetine (which is a selective serotonin reuptake inhibitor used for premature ejaculation). Vardenafil works by increasing blood flow to the penis, helping with erectile function, while Dapoxetine works to delay ejaculation. Together, they aim to address both erectile dysfunction and premature ejaculation. It's important to use this medication as prescribed by a doctor and to be aware of potential side effects, such as dizziness, headaches, or digestive issues.
