Mild erectile dysfunction has been associated with alcohol use. However, the association is reversible after cessation of alcohol use. The most common alcohol-related use is with the use of nitroglycerin, a commonly used anti-inflammatory drug. This drug is not approved by the Food and Drug Administration (FDA) for the treatment of erectile dysfunction. In most cases, it is taken for longer periods of time than prescribed. Alcohol use is a significant cause of erectile dysfunction, and many people with ED are reluctant to stop drinking. In the U. S., men who drink alcohol take nitroglycerin, but not the nitrates. The use of the drug for this purpose is considered to be medically insignificant. For nitrates, a class of medicines called organic nitrates (such as glyceryl trinitrate) is used for the treatment of angina. S., alcohol consumption is considered to be a problem that must be addressed. Alcohol is a depressant that is not used in the U. S., so it is not a drug that should be taken for the treatment of ED.
