What is chlorpheniramine, codeine, and pseudoephedrine?
Codeine is a narcotic cough suppressant. It affects the signals in the brain that trigger cough reflex.
Chlorpheniramine, codeine, and pseudoephedrine is a combination medicine used to treat runny or stuffy nose, sneezing, itching, watery eyes, cough, and sinus congestion caused by allergies, the common cold, or the flu.
Chlorpheniramine, codeine, and pseudoephedrine may also be used for purposes not listed in this medication guide.
Codeine can slow or stop your breathing, and may be habit-forming. MISUSE OF THIS MEDICINE CAN CAUSE ADDICTION, OVERDOSE, OR DEATH, especially in a child or other person using the medicine without a prescription.
This medicine is not for use in anyone under 18.
Before taking this medicine
You should not use chlorpheniramine, codeine, and pseudoephedrine if you are allergic to codeine, pseudoephedrine, or chlorpheniramine.
Do not use this medicine if you have used an MAO inhibitor in the past 14 days. A dangerous drug interaction could occur. MAO inhibitors include isocarboxazid, linezolid, methylene blue injection, phenelzine, rasagiline, selegiline, tranylcypromine, and others.
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.
Do not give this medicine to anyone younger than 18 years old.
To make sure this medicine is safe for you, tell your doctor if you have:
asthma, COPD, bronchitis, or other breathing disorders;
a cough with mucus;
heart disease, high blood pressure;
a thyroid disorder; or
enlarged prostate and urination problems.
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.
Do not breast-feed. Codeine can pass into breast milk and may cause drowsiness, breathing problems, or death in a nursing baby. Chlorpheniramine may slow breast milk production.
How should I take chlorpheniramine, codeine, and pseudoephedrine?
Follow all directions on your prescription label. Codeine can slow or stop your breathing. Never use chlorpheniramine, codeine, 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.
You should not use antihistamine medication to make a child sleepy.
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.
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. Do not freeze.
Keep track of your medicine. Codeine is a drug of abuse and you should be aware if anyone is using your medicine improperly or without a prescription.
What happens if I miss a dose?
Since chlorpheniramine, codeine, and pseudoephedrine is taken when needed, you may not be on a dosing schedule. If you are taking the medication regularly, take the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not take extra medicine to make up the missed dose.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. A codeine overdose can be fatal, especially in a child or other person using the medicine without a prescription. Overdose symptoms may include slow breathing and heart rate, severe drowsiness, muscle weakness, cold and clammy skin, pinpoint pupils, and fainting.
What should I avoid while taking chlorpheniramine, codeine, and pseudoephedrine?
chlorpheniramine, codeine, and pseudoephedrine may impair your thinking or reactions. Avoid driving or operating machinery until you know how this medicine will affect you. Dizziness or severe drowsiness can cause falls or other accidents.
Do not drink alcohol while you are taking medicine that contains codeine. Dangerous side effects or death could occur.
Ask a doctor or pharmacist before using any other cold, allergy, cough, or sleep medicine. Many combination medicines contain antihistamines, decongestants, or cough suppressants. Taking certain products together can cause you to get too much of a certain drug.
