Mucinex dm Uses and Side Effects

mucinex dm

The Mucinex Dm ingredients are Dextromethorphan and guaifenesin. Dextromethorphan is used to suppress cough. It works by affecting the brain and signals which are likely to trigger the coughing response, hence Dextromethorphan is known commonly as a cough suppressant.
