Dextromethorphan (DXM): Definition, Uses & Abuse

Dextromethorphan (DXM) is a cough suppressant found in many cold medications that are sold over the counter. As with any drug, DXM has the potential for abuse. DXM abusers seek a high that may produce euphoria and hallucinations.

Functions

• Coughing is a condition leading to legal use of DXM

  DXM is commonly found in at least 120 over-the-counter cough suppressants, sometimes alone and sometimes combined with other pain relievers, decongestants or expectorants.

Abuse

• Easy access to DXM is a factor in its abuse by young people

  Abuse of DXM by young people is a common problem. DXM is easy to obtain, and many websites detail how much DXM must be taken to feel the "high" effects.

Side Effects

• Natural cough relief products without dextromethorphan

  Legal, properly measured use of DXM to relieve cough symptoms can cause side effects that include dizziness, anxiety, nervousness, restlessness, confusion, hallucinations, slowed or shallow breathing, and nausea.

Considerations

• Cough syrup contains dextromethorphan

  Any other over-the-counter cold medicines should not be taken with DXM unless advised by a doctor. Avoid antidepressants and some hypertension medications while taking DXM.

Warnings

• Some medications to avoid while on dextromethorphan

  DXM combined with alcohol can cause death. Diet pills, caffeine and stimulants should all be avoided while on DXM.
