    depends on specifics

    Korea Customs lists dextromethorphan as a psychotropic ingredient under the Narcotics Control Act: bringing it in without approval is punishable by up to 10 years' imprisonment or a fine of up to KRW 100 million. The exception is carrying medicine for your own treatment with prior approval from the Minister of Food and Drug Safety (apply through nedrug.mfds.go.kr; see Korea's controlled-medication entry).

    Korea Customs names NyQuil, DayQuil, Robitussin, Mucinex and Delsym among dextromethorphan medicines it has found at the border. Not every version of these brands contains dextromethorphan: check the active ingredients on your pack.
