Product Key Features
As an over-the-counter cough remedy, DXM is an effective way of dealing with the symptoms of the common cold or flu. DXM belongs to a class of medications known as antitussives, which work to suppress cough by reducing activity in regions of the brain that cause coughing. Typically, people seeking to abuse DXM seek out formulations labeled “Extra Strength” or “DM Max,” which have a high concentration of the active ingredient. Medications that contain other active ingredients, such as acetaminophen or guaifenesin, are typically avoided due to the potential side effects that would occur when taken at high doses.

These rates declined 58.3% from 2006–2015 to 80.9 calls per million population. Currently, the recreational use of dextromethorphan accounts for roughly 6,000 emergency department visits per year in the United States.
