  • 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.

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.
