Uses
This medication is used for temporary relief of coughs caused by certain respiratory tract infections (e.g., bronchitis, sinusitis, or the common cold), especially when the cough produces phlegm or congestion. This product is, generally, not used for the chronic cough from smoking or chronic breathing problems (e.g., chronic bronchitis, emphysema), unless directed by your doctor.
Guaifenesin is called an expectorant. It works by thinning phlegm in the respiratory tract. This helps the cough to clear phlegm better.
This form of the medication is not recommended for use in children under 12 years of age. To decrease the risk for serious side effects, carefully follow all dosage directions. Do not give other cough and cold medication that might contain the same or similar ingredients (see also Drug Interactions section). Ask your doctor or pharmacist about other ways to relieve cough and cold symptoms (e.g., saline nose drops/spray, using a humidifier or infant nasal suction bulb).
