What Are Some Cough Syrups That Contain Codeine?

Some cough syrups that contain codeine are Robitussin-AC, Cheratussin AC, Codar GF, M-Clear and Tylenol with Codeine, according to Drugs.com. Robitussin-AC treats coughs through the action of codeine and guaifenesin. Guaifenesin is an expectorant, which helps loosen phlegm in the patient's throat and chest.

Cheratussin AC, Codar GF and M-Clear also use codeine and guaifenesin, while Tylenol with Codeine mixes acetaminophen with the narcotic, claims Drugs.com. Liquid Tylenol with Codeine officially eases pain, but the codeine in the medicine also suppresses cough, according to MedicineNet.

Because codeine is habit-forming, individuals should not take the cough medicines for a long period of time, according to Drugs.com. Patients should also avoid operating heavy machinery or driving while they are taking the drug.
