Chemically, it is an ether of guaiacoland glycerine. It may be used in combination with other medications. A 2014 study found that guaifenesin has no effect on sputum production or clearance in upper respiratory infections.

Side effects may include dizziness, sleepiness, skin rash, and nausea. While it has not been properly studied in pregnancy, it appears to be safe. It is believed to work by making airway secretions more liquid.

Guaifenesin is used to try to help with coughing up thick mucus, and is sometimes combined with the antitussive (cough suppressant) dextromethorphan, such as in Mucinex DM or Robitussin DM. It is also combined with ephedrine in Primatene and Bronkaid tablets for symptomatic relief of asthma.
