There are several medications that are known to interact with Levitra, so be sure to tell your doctor about all medications you are taking including those you can get without a prescription. Levitra has not been studied with other treatments for impotence, so use in combination with other treatments is not recommended. Limit alcohol intake, as it may aggravate SIDE EFFECTS of Levitra.
