What is M-Clear?

Codeine is a narcotic cough suppressant. It affects the signals in the brain that trigger cough reflex.

Guaifenesin is an expectorant. It helps loosen congestion in your chest and throat, making it easier to cough out through your mouth.

M-Clear is a combination medicine used to treat cough and chest congestion caused by allergies, the common cold, or the flu.

M-Clear will not treat a cough that is caused by smoking, asthma, or emphysema.

M-Clear may also be used for purposes not listed in this medication guide.

Codeine can slow or stop your breathing, and may be habit-forming. MISUSE OF THIS MEDICINE CAN CAUSE ADDICTION, OVERDOSE, OR DEATH, especially in a child or other person using the medicine without a prescription.

Do not give this medicine to anyone under 18.
