Cheratussin DAC syrup is a combination of codeine, guaifenesin, and pseudoephedrine used to treat cough and nasal congestion caused by the common cold. The product contains 100 mg of guaifenesin, 30 mg of pseudoephedrine hydrochloride, and 10 mg of codeine phosphate per 5 mLs. Guaifenesin loosens and thins secretions, pseudoephedrine is a decongestant, and codeine inhibits cough.
