dextromethorphan hydrobromide

Dextromethorphan hydrobromide is a synthetic drug related to morphine, primarily used as a cough suppressant in medicine. It is a white crystalline powder that dissolves in water, alcohol, and chloroform. This drug works by acting on the central nervous system to reduce the cough reflex.1

Unlike some other morphine derivatives, dextromethorphan does not cause addiction or central nervous system depression, nor does it have pain-relieving properties. Because of this, it is commonly found in over-the-counter cough syrups and tablets.1

However, dextromethorphan is also used recreationally as DXM. In large doses, it can alter sensory perception and cause hallucinations. Abuse of the drug has been linked to memory impairment and other cognitive issues. Taking large doses with antidepressants or other medications can lead to fatal respiratory and cardiac distress.1
