and dextromethorphan polistirex
is one stronger than the other…? or what
Dextromethorphan hydrobromide is the shorter-acting form of OTC (over-the-counter) cough syrups (i.e, Robitussin), whereas dextromethorphan polistirex is the longer-acting form (Delsym) of basically the exact same thing. The hydrobromide forms are generally taken every 4-6 hours, while the polistirex forms are an extended-release form, taken every 12 hours.
Both are of equal strength, per se; the difference is how quickly the body metabolizes the two different sub-ingredients of the dextromethorphan.

USP means that it is listed in complies with the USP. “The United States Pharmacopeia (USP) is an official public standards–setting authority for all prescription and over–the–counter medicines and other health care products manufactured or sold in the United States.” HBr stands for hydro-bromide. It describes chemically the type of solution. For the most part it does not mean anything to the consumer, but is a technical designation. Another designation for medications is HCL (hydrochloride).

Dextromethorphan is dextromethorphan, but the polistirex takes much longer to metabolize into dextrorphan, which is what most people actually want when they take DXM. Delysm says long lasting, I say double ineffective. But I understand it tastes much better, so it’s got that going for it.
