What is M-Clear?
Codeine suppresses coughing. It interferes with the brain signals that cause the cough reflex. Guaifenesin acts as an expectorant. It loosens congestion in the chest and throat, making it easier for you to cough through your mouth. M-Clear, a combination of medicines, is used to treat allergies, flu, and coughs caused by the common virus. M-Clear does not treat coughs caused by smoking or emphysema. This medication guide does not list all possible uses of M-Clear.
