yeah it will work, but high doses of guaifenesin make you puke. at least to my knowledge it will work cause the dxm is in there
enthused Reviewed by enthused on . DXM or not? I have a full bottle of Rite-Aid Tussin DM, but I'm confused as to whether this will produce a trip or not. it says Non-narcotic on the front, but Dextromethorphan is an active ingredient it says on the back. here's what it says: Active Ingredients (in each 5mL teaspoonful) Gualfenesin 100mg.............Expectorant Dextromethorphan HBr, USP 10mg..............Cough Suppressant Rating: 5
