Dextromethorphan (DXM) is the active ingredient in many cough suppressants in a variety of over-the-counter nonprescription cough remedies such as Vicks, Robitussin and TheraFlu.
Originally created as a non-addictive alternative to codeine by the CIA and Navy in the 50s, dextromethorphan (DXM) received FDA approval for use in over-the-counter medications in 1958. Today DXM continues to be sold in liquid, capsule, spray and tablet form.
