What is codeine, guaifensin, and pseudoephedrine?
Codeine is a narcotic cough suppressant. It affects the signals in the brain that trigger cough reflex.
Guaifenesin is an expectorant. It helps loosen congestion in your chest and throat, making it easier to cough out through your mouth.
Pseudoephedrine is a decongestant that shrinks blood vessels in the nasal passages. Dilated blood vessels can cause nasal congestion (stuffy nose).
Codeine, guaifenesin, and pseudoephedrine is a combination medicine used to treat stuffy nose, cough, sinus congestion, and chest congestion caused by allergies, the common cold, or the flu.
This medicine will not treat a cough that is caused by smoking, asthma, or emphysema.
Codeine, guaifenesin, and pseudoephedrine may also be used for purposes not listed in this medication guide.

Do not use this medicine if you have used an MAO inhibitor in the past 14 days, such as isocarboxazid, linezolid, methylene blue injection, phenelzine, rasagiline, selegiline, or tranylcypromine.
Codeine can slow or stop your breathing. Never use this medicine in larger amounts, or for longer than prescribed. Codeine may also be habit-forming. Never share this medicine with another person. MISUSE OF NARCOTIC MEDICINE CAN CAUSE ADDICTION, OVERDOSE, OR DEATH.

Always ask a doctor before giving codeine, guaifenesin, and pseudoephedrine to a child. Death can occur from the misuse of cough and cold medicines in very young children. Medicines that contain codeine should not be given to a child just after surgery to remove the tonsils or adenoids.
In some people, codeine breaks down rapidly in the liver and reaches higher than normal levels in the body. This can cause dangerously slow breathing and may cause death, especially in a child.
To make sure codeine, guaifenesin, and pseudoephedrine is safe for you, tell your doctor if you have:

a history of drug or alcohol addiction;
a history of head injury or brain tumor; or

It is not known whether this medicine will harm an unborn baby. If you use codeine while you are pregnant, your baby could become dependent on the drug. This can cause life-threatening withdrawal symptoms in the baby after it is born. Babies born dependent on habit-forming medicine may need medical treatment for several weeks. Tell your doctor if you are pregnant or plan to become pregnant.
Codeine can pass into breast milk and may harm a nursing baby. The use of codeine by some nursing mothers may lead to life-threatening side effects in the baby. Do not use this medicine without telling your doctor if you are breast-feeding a baby.
How should I take Maxifed CD (codeine, guaifenesin, and pseudoephedrine)?
Follow all directions on your prescription label. Codeine can slow or stop your breathing. Never use codeine, guaifenesin, and pseudoephedrine in larger amounts, or for longer than prescribed. Cough or cold medicine is usually taken only for a short time until your symptoms clear up.
Codeine may be habit-forming, even at regular doses. Never share this medicine with another person, especially someone with a history of drug abuse or addiction. MISUSE OF NARCOTIC MEDICINE CAN CAUSE ADDICTION, OVERDOSE, OR DEATH, especially in a child or other person using the medicine without a prescription. Selling or giving away codeine is against the law.
Measure liquid medicine with the dosing syringe provided, or with a special dose-measuring spoon or medicine cup. If you do not have a dose-measuring device, ask your pharmacist for one.
Drink extra fluids to help loosen the congestion and lubricate your throat while you are taking this medicine.
Call your doctor if your symptoms do not improve after 7 days of treatment, or if you have a fever with a headache or skin rash.
If you need surgery or medical tests, tell the surgeon or doctor ahead of time if you have taken a cough or cold medicine within the past few days.
Store at room temperature away from moisture and heat. Keep track of the amount of medicine used from each new bottle. Codeine is a drug of abuse and you should be aware if anyone is using your medicine improperly or without a prescription.
