What Is Levitra?

Levitra is a prescription medication used to treat erectile dysfunction (ED), a condition in which a man has difficulty achieving or maintaining an erection suitable for sexual activity.

How Does Levitra Work?

Levitra blocks the PDE5 enzyme, allowing levels of cyclic guanosine monophosphate (cGMP) to remain elevated. This relaxes blood vessels in the penis and increases blood flow during sexual stimulation, making it easier to achieve and maintain an erection.

Most men begin to notice effects within 30 to 60 minutes after taking Levitra.

Some individuals may respond in as little as 25 minutes.
