This combination product contains 3 medications: codeine, triprolidine, and pseudoephedrine.

Codeine belongs to the group of medications called narcotic analgesics and cough suppressants.

Triprolidine belongs to the group of medications called antihistamines, and helps to relieve sneezing and runny nose.

Pseudoephedrine belongs to the group of medications called nasal decongestants, and reduces nasal congestion.

Codeine - triprolidine - pseudoephedrine is used to treat coughs related to inflamed tissues in the nose and throat. It works by reducing inflammation in the nose and throat tissues and decreasing cough.

This medication may be available under multiple brand names and/or in several different forms. Any specific brand name of this medication may not be available in all of the forms or approved for all of the conditions discussed here. As well, some forms of this medication may not be used for all of the conditions discussed here.

Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. If you have not discussed this with your doctor or are not sure why you are taking this medication, speak to your doctor. Do not stop taking this medication without consulting your doctor.

Do not give this medication to anyone else, even if they have the same symptoms as you do. It can be harmful for people to take this medication if their doctor has not prescribed it.

Note: A cough is a symptom. Before taking a cough suppressant, it is important to assess the underlying cause of the cough.

The recommended dose for adults is 10 mL (2 teaspoons), every 6 or 8 hours as needed. No more than 4 doses should be taken in a 24-hour period.

Many things can affect the dose of a medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are taking the medication without consulting your doctor.

Use an oral syringe to measure each dose of the liquid, as it gives a more accurate measurement than household teaspoons.

Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.

Abdominal conditions: Codeine, like other narcotic medications, may make the diagnosis of abdominal conditions more difficult or it may worsen these conditions. If you are scheduled for abdominal surgery or have an abdominal condition such as inflammatory or obstructive bowel disease, acute cholecystitis, or pancreatitis, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Breathing: Codeine can suppress breathing. Children are more likely to experience serious breathing problems, including death. For this reason, this medication should not be given to people less than 18 years old. If you are at risk of breathing difficulties, such as asthma, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Constipation: Codeine can be very constipating. Eating a high-fibre diet and following good bowel habits will help to minimize this effect. If you develop constipation easily, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Dependence and withdrawal: This medication contains codeine. Physical dependence, psychological dependence, and abuse have occurred with the use of codeine. People with a history of past or current substance use problems may be at greater risk of developing abuse or addiction while taking this medication. Abuse is not a problem with people who require this medication for pain relief.

If you suddenly stop taking this medication, you may experience withdrawal symptoms such as anxiety, sweating, trouble sleeping, shaking, pain, nausea, tremors, diarrhea, and hallucinations. If you have been taking this medication for a while, it should be stopped gradually as directed by your doctor.

Diabetes: The pseudoephedrine in this medication may cause blood sugar to become less controlled for people with diabetes. This medication also contains sugar, which may increase blood glucose levels. It may become necessary to test your blood glucose levels more often when taking codeine - triprolidine - pseudoephedrine - guaifenesin.

If you have diabetes, or are at risk of developing diabetes, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Drowsiness/reduced alertness: Codeine may cause drowsiness. Do not drive, operate machinery, or perform any potentially hazardous tasks until you know how this medication affects you.

Glaucoma: Codeine - triprolidine - pseudoephedrine may make glaucoma worse. It may also cause glaucoma to develop. If you have narrow-angle glaucoma or are at risk of developing glaucoma, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Head injury: If you have a head injury or increased pressure in the head, you may have a higher risk of experiencing side effects (breathing problems) or worsening of their condition while taking this medication. Discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Heart disease: This medication may make symptoms of certain heart conditions worse. If you have an irregular heart rhythm, ischemic heart disease, high blood pressure or other heart condition, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Kidney disease: If you have kidney disease or reduced kidney function, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Liver disease: If you have liver disease, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Other medical conditions: The medications in codeine - triprolidine - pseudoephedrine can have an effect on other medical conditions. The codeine may make symptoms of delirium tremens or acute alcohol intoxication worse. As well, triprolidine and pseudoephedrine may worsen symptoms of low thyroid (hypothyroidism), Addison's disease, benign prostatic hypertrophy (enlarged prostate), gallbladder disease, urethral stricture, decreased function of the adrenal glands, or porphyria. If you have any of these conditions, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Pregnancy: This medication should not be used during pregnancy. If you become pregnant while taking this medication, contact your doctor immediately.

Breast-feeding: This medication passes into breast milk. Some of the codeine dose is converted into morphine by the body, once it has been taken. For some people, this change happens much faster than for others. If this happens to a nursing mother, the baby is at risk of receiving a morphine overdose through the breast milk. If you are a breast-feeding mother and are taking codeine - triprolidine - pseudoephedrine, it may affect your baby. Taking this medication while breast-feeding is not recommended.

Children:  Codeine - triprolidine - pseudoephedrine should not be given to children less than 18 years of age.

Seniors: This medication is more likely to cause side effects for those 60 years of age and older. Lower doses may be necessary.
