The genus name is from the Greek klōstēr (κλωστήρ), "spindle", and the specific name is from Latin difficile, neuter singular form of difficilis "difficult, obstinate", chosen in reference to fastidiousness upon culturing. Regarding the pronunciation of the current and former genus assignments, Clostridioides is  and Clostridium is . Both genera still have species assigned to them, but this species is now classified in the former. Via the norms of binomial nomenclature, it is understood that the former binomial name of this species is now an alias. Regarding the specific name,  is the traditional norm, reflecting how medical English usually pronounces naturalized New Latin words (which in turns largely reflects traditional English pronunciation of Latin), although a restored pronunciation of  is also sometimes used (the classical Latin pronunciation is reconstructed as [kloːsˈtrɪdɪ.ũː dɪfˈfɪkɪlɛ]).
Some states have restricted the sale of dextromethorphan to adults or put other restrictions on its purchase in place, similar to those for pseudoephedrine. As of January 1, 2012, dextromethorphan is prohibited for sale to minors in the State of California and in the State of Oregon as of January 1, 2018, except with a doctors prescription. Several other states have also begun regulating sales of dextromethorphan to minors. In Indonesia, the National Agency of Drug and Food Control (BPOM-RI) prohibited single-component dextromethorphan drug sales with or without prescription. Indonesia is the only country in the world that makes single-component dextromethorphan illegal even by prescription and violators may be prosecuted by law. National Anti-Narcotics Agency (BNN RI) has even threatened to revoke pharmacies and drug stores licenses if they still stock dextromethorphan, and will notify the police for criminal prosecution. As a result of this regulation, 130 medications have been withdrawn from the market, but those containing multicomponent dextromethorphan can still be sold over the counter. Society and culture
