What is EndaCof-AC?
Brompheniramine is an antihistamine that reduces the effects of natural chemical histamine in the body. Histamine can produce symptoms of sneezing, itching, watery eyes, and runny nose.
Codeine is a narcotic cough suppressant. It affects the signals in the brain that trigger cough reflex.
EndaCof-AC is a combination medicine used to treat runny nose, sneezing, itching, watery eyes, and cough caused by allergies, the common cold, or the flu.
EndaCof-AC will not treat a cough that is caused by smoking, asthma, or emphysema.
EndaCof-AC 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.
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.
Ask a doctor before giving this medicine to a child younger than 12 years old. Do not give this medicine to anyone under 18 who recently had surgery to remove the tonsils or adenoids.
Fatal side effects can occur if you use this medicine with alcohol, or with other drugs that cause drowsiness or slow your breathing.
Before taking this medicine
You should not use this medicine if you are allergic to brompheniramine or codeine.
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.
Ask a doctor before giving this medicine to a child younger than 12 years old.
Medicines that contain codeine should not be used in anyone under 18 who recently had surgery to remove the tonsils or adenoids.
To make sure EndaCof-AC is safe for you, tell your doctor if you have ever had:
asthma or other breathing problems;
a head injury or brain tumor;
a blockage in your digestive tract (stomach or intestines);
enlarged prostate, urination problems;
liver or kidney disease;
a thyroid disorder; or
alcoholism or drug addiction.
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. Brompheniramine may slow breast milk production.
How should I take EndaCof-AC?
Follow all directions on your prescription label. Codeine can slow or stop your breathing. Never use EndaCof-AC 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.
Do not take for longer than 7 days in a row. 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 this medicine within the past few days.
Store at room temperature away from moisture and heat. Do not allow the liquid to 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 this medicine is taken when needed, you may not be on a dosing schedule. If you are taking the medicine 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.

What should I avoid while taking EndaCof-AC?
This medicine 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.
Avoid getting up too fast from a sitting or lying position, or you may feel dizzy. Get up slowly and steady yourself to prevent a fall.
Do not drink alcohol while you are taking medicine that contains codeine. Dangerous side effects or death can occur when alcohol is combined with a narcotic medicine.
Ask a doctor or pharmacist before using any other cold, allergy, cough, or sleep medicine. Many combination medicines contain antihistamines or cough suppressants. Taking certain products together can cause you to get too much of a certain drug.
