Patient Education

Codeine


Codeine is used to relieve mild to moderate pain. It is also used, usually in combination with other medications, to reduce coughing. Codeine will help relieve symptoms but will not treat the cause of symptoms or speed recovery. Codeine belongs to a class of medications called opiate (narcotic) analgesics and to a class of medications called antitussives. When codeine is used to treat pain, it works by changing the way the brain and nervous system respond to pain. When codeine is used to reduce coughing, it works by decreasing the activity in the part of the brain that causes coughing. Codeine is also available in combination with acetaminophen (Capital and Codeine, Tylenol with Codeine), aspirin, carisoprodol, and promethazine and as an ingredient in many cough and cold medications. This monograph only includes information about the use of codeine. If you are taking a codeine combination product, be sure to read information about all the ingredients in the product you are taking and ask your doctor or pharmacist for more information.

Guaifenesin


Guaifenesin is used to relieve chest congestion. Guaifenesin may help control symptoms but does not treat the cause of symptoms or speed recovery. Guaifenesin is in a class of medications called expectorants. It works by thinning the mucus in the air passages to make it easier to cough up the mucus and clear the airways.
