Interaction Details
Chlorpheniramine Polistirex, Codeine Polistirex is classified as belonging to the following category: Cns Depressants
Theoretically, nutmeg might increase the risk of additive sedation when taken with CNS depressants.
Animal studies suggest that nutmeg extracts and several volatile oils in nutmeg, such as methyleugenol, isoeugenol, safrole, myristicin, trimyristin, 1,8-cineole, and geranyl acetate, have sedative effects. One animal study shows that petroleum ether extracts of nutmeg can potentiate the effects of pentobarbital or phenobarbital. However, evidence from other animal research suggests that the nutmeg constituent myristicin can actually reduce sleeping time in rats pretreated with phenobarbital.
