Children should not use products that contain codeine after certain surgeries (including tonsil/adenoid removal). Also, for children younger than 12 years, do not use codeine to treat cough or pain unless specifically directed by the doctor. Use of codeine is not recommended to treat cough and pain in children between 12 and 18 years old who have breathing problems. Some children are more sensitive to codeine and have had very serious (rarely fatal) breathing problems such as slow/shallow breathing (see also Side Effects section). Talk with your doctor or pharmacist about the risks and benefits of this medication.Who should not take Guaitussin with Codeine?
See also Warning section.
This combination medication is used to temporarily treat coughing and chest congestion symptoms caused by the common cold, flu, or other breathing illnesses (e.g., sinusitis, bronchitis). Guaifenesin is an expectorant that helps thin and loosen mucus in the lungs, making it easier to cough up the mucus. Codeine is a narcotic cough suppressant (antitussive) that affects a certain part of the brain, reducing the urge to cough.
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.
Take this medication by mouth with or without food, usually every 4 to 6 hours as needed with a full glass of water (8 ounces or 240 milliliters) or as directed by your doctor. This medication can be taken with food if stomach upset occurs. Drink plenty of fluids while you are using this medication unless otherwise directed by your doctor. The fluid will help loosen the mucus in your lungs.
If you are using the liquid form, use a medication-measuring device to carefully measure the prescribed dose. Do not use a household spoon.
Some liquids need to be shaken before pouring each dose. Check your bottle or ask your pharmacist if your product needs to be shaken.
This medication may cause withdrawal reactions, especially if it has been used regularly for a long time (more than a few weeks) or in high doses. In such cases, withdrawal symptoms (such as anxiety, restlessness, sweating, shaking chills, nausea, vomiting, and diarrhea) may occur if you suddenly stop using this medication. To prevent withdrawal reactions, your doctor may reduce your dose gradually. Consult your doctor or pharmacist for more details, and report any withdrawal reactions right away.
Though very unlikely, abnormal drug-seeking behavior (addiction) is possible with this medication. Do not increase your dose, take it more frequently, or take it for a longer time than prescribed. Properly stop the medication when so directed.

Get medical help right away if you have any very serious side effects, including: seizure.
Codeine is changed into a strong narcotic drug (morphine) in your body. In some people, this change happens faster and more completely than usual, which increases the risk of very serious side effects. Get medical help right away if you notice any of the following: slow/shallow breathing, unusual drowsiness/difficulty waking up, confusion.
A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.
