Also, for children younger than 12 years, do not use codeine or dihydrocodeine to treat cough or pain unless specifically directed by the doctor.

USES: See also Warning section.This combination product is used to treat symptoms caused by the common cold, flu, allergies, hay fever, or other breathing illnesses (e.g., sinusitis, bronchitis). Guaifenesin is an expectorant that helps to thin and loosen mucus in the lungs, making it easier to cough up the mucus. Decongestants relieve stuffy nose symptoms.

Antihistamines relieve watery eyes, itchy eyes/nose/throat, runny nose, and sneezing.This medication is not usually used for ongoing coughs from smoking, asthma, other long-term breathing problems (e.g., emphysema), or coughs with a lot of mucus, unless directed by your doctor.Cough-and-cold products have not been shown to be safe or effective in children younger than 6 years. Therefore, this product is not recommended to treat cold symptoms in children younger than 6 years. Some products (including some long-acting tablets/capsules) are not recommended for use in children younger than 12 years. Ask your doctor or pharmacist for more details about using your product safely.These products do not cure or shorten the length of the common cold and may cause serious side effects. To decrease the risk for serious side effects, carefully follow all dosage directions. Giving more than the recommended dose or using this medication along with other cough-and-cold products has resulted in serious (even fatal) side effects, including slowed/stopped breathing. Talk to the doctor or pharmacist before giving other cough-and-cold medication that might contain the same or similar ingredients (see also Drug Interactions section). Ask about other ways to relieve cough and cold symptoms (such as drinking enough fluids, using a humidifier or saline nose drops/spray). Do not use this product to make a child sleepy.
