What is DXM

Dextromethorphan, known in short as DXM, is a cough suppressant medication of the morphinan class, available over-the-counter (OTC). It is also used as a stimulant, sedative and dissociative drug.

People with normal metabolism have been observed eliminating half the dextromethorphan ingested within 2-4 hours, but some people with poor metabolism may take up to 3-6 hours to excrete half of the dextromethorphan taken.

Thus we can see that while individuals with healthy metabolism may clear dextromethorphan between 11 and 22 hours, poor metabolizers will take between 16½ to 33 hours for complete elimination.

In conclusion, it is going to take a maximum of 33 hours after you have last taken dextromethorphan, for it to be eliminated from your system.

Timeframes are, however, variable depending on certain factors:

  • Age
  • Body mass
  • Hydration and food intake levels
  • Liver and kidney conditions
  • Metabolic rate
  • Dose taken
  • Frequency
