According to a recent news release by Bayer/GlaxoSmithKline, ninety percent (90%) of men reported improved erections. Each Levitra pill may work in as quickly as 25 minutes and may work for up to 24 hours.

Levitra acts in the same way as Viagra, by blocking an enzyme called phosphodiesterase-5, or PDE-5. This helps the smooth muscles in the penis to relax, which effectively increases blood flow. Thus, allowing the penis to become and stay harder longer.

Take a Levitra tablet about 25 to 60 minutes before sexual activity. With sexual stimulation you may achieve an erection anywhere from 25 minutes up to four to five hours after taking Levitra. Swallow one tablet with a glass of water. You can take Levitra with or without food - but preferably not after a heavy or high-fat meal.
