Dextromethorphan (DXM) is a cough-suppressing ingredient found in a variety of over-the-counter cold and cough medications, usually sold in the form of a liquid, tablets or gel caps. Like PCP and Ketamine, dextromethorphan is a dissociative anesthetic, meaning DXM effects can include hallucinations.
DXM may produce euphoria and mind-altering effects when taken in quantities greater than the recommended treatment dose. People who misuse DXM describe different “plateaus” ranging from mild distortions of color and sound to visual hallucinations and “out-of-body” sensations, and loss of motor control.
When being misused, common slang terms for DXM include dex, robo, skittles, triple C and tussin.
Signs of DXM misuse include confusions, dizziness, slurred speech, abdominal pain, nausea and vomiting, and disorientation. If you’re concerned your child may be misusing DXM or other substances, the following resources can prepare you to address the behavior more effectively.
