Hey, I dont have any robitussin or coricidin. I found a brand new unopen bottle of equate tussin DM cough suppressant expectorant. would this work. The bottle is 4 FL OZ. how much would i take? It says active ingredients
Dextromethorphan HBr, USP 10mg
**also, at the top it says "Compare to Robitussin DM active ingredients"...if that means anything
