Levitra is used for the treatment of erectile dysfunction and male impotence, as well as for other purposes. It is a phosphodiesterase inhibitor which boosts the blood flow in to the penis, helping to achieve and maintain an erection during sexual intercourse. However, sexual stimulation is required as an erection will not occur just by taking Levitra. The effect can last for up to 6 hours, with fewer side effects than Viagra, there are no food or alcohol restrictions and fewer side effects.
Method of Use
It is recommended that Levitra is taken orally 25-45 minutes prior to sexual activity. Its effect will start within 16 minutes and will last for up to 6 hours. Levitra can be taken daily at approximately the same time, with or without food, and as directed by your doctor. Avoid taking more than one dose in any 24 hour period and as Levitra can be taken as needed, you do not need to follow a dosing schedule.
Levitra is to be stored at room temperature, between 59°F and 86°F (15-30°C), in its original container, away from heat, light and moisture. It must not be stored in the bathroom. The product must be kept out of the reach of children and pets at all times. Any medication that is out of date should be disposed of safely (any pharmacist will be able to advise you on disposal instructions).

- are allergic to any ingredients used in the manufacture of Levitra;
