Will mucinex (guaifenesin) dm clear post nasal drip?

A doctor has provided 1 answer

Probably not: Mucinex (guaifenesin) dm contains guifenisin, a mucous thinner, and dextromethorphan, non-narcotic cough supressant, and is good for thinning thick mucous and helping a cough, but will not clear post nasal drainage.
