DXM (Dextromethorphan) — Understanding
Risks, Signs & Treatment
DXM is found in over-the-counter cough medicine — and misused at high doses for dissociative effects that carry real health and addiction risks.
Understanding the substance.
Dextromethorphan (DXM) is a cough suppressant present in many OTC medications (Robitussin, NyQuil). At therapeutic doses it is safe. At high doses, it acts on NMDA receptors to produce dissociation, euphoria, and hallucinations. Misuse is common among adolescents due to easy OTC access. Chronic high-dose use can cause cognitive damage and psychological dependence.
