Since most of these medications are designed to take as needed for symptoms, you may not adhere to a strict dosing schedule.

It is not recommended to take an extra dose just because you missed one.

Taking these medications while taking Mucinex may negatively affect the impact of the medication. If you take other expectorants while taking Mucinex, you could be getting too much of a particular drug combination. Check the label on any new expectorant and seek medical advice before taking it.
