What is Mucinex?

It is mainly an expectorant, which means it reduces phlegm and clears the airway. It works by increasing the volume and lowering the viscosity of the phlegm produced in the airways and lungs. This causes coughing out all the excess mucus. It is an over-the-counter medication that is available in both liquid and oral tablet form.
