Dextromethorphan is a medication often used in over-the-counter cough medicines.[3] In cough medicine it may be combined with paracetamol (acetaminophine), chlorpheniramine, pseudoephedrine, or guaifenesin.[3] There is no clear evidence of benefit in children under six to twelve years of age with some evidence of harm; thus such use is not recommended.[3][4] It is taken by mouth.[3]

Side effects may include nausea, sleepiness, and dizziness.[3] Serious side effects may include serotonin syndrome and abuse.[3] While safety in pregnancy and breastfeeding has not been studied, such use is believed to be okay.[5][6] It is in the morphinan class of medications and acts within the brain to suppress coughing.[3][4]

Dextromethorphan was patented in 1949 and approved for medical use in 1953.[7] Dextromethorphan is also used recreationally.[3] At high doses dextromethorphan acts as a dissociative hallucinogen and may result in seizures.[8] A number of other uses for dextromethorphan are being studied.[9]
