How does this medication work? What will it do for me?
This combination product contains 4 medications: codeine, triprolidine, pseudoephedrine, and guaifenesin.
Codeine belongs to the group of medications called narcotic analgesics and cough suppressants. It works by blocking pain signals that are sent out by the brain to various areas of the body and reduces coughing by acting in the brain to dull the cough reflex.
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 is used to decrease nasal stuffiness.
Guaifenesin belongs to the group of medications called expectorants. This medication helps to loosen mucus so it can be coughed up.
Codeine - triprolidine - pseudoephedrine - guaifenesin is used to help remove mucus from the breathing passages and to control coughing related to inflamed tissues in the nose and throat. It works by reducing inflammation in the nose and throat tissues and decreasing cough. It also loosens mucus, making it easier to cough up.

Are there any other precautions or warnings for this medication?
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, 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.
Accidental use: When this medication is used by anyone other than the person for whom it was prescribed, the effects of the medication may be fatal. Keep this medication out of sight and reach of children.
Adrenal gland problems: Adrenal glands produce chemical messengers that are responsible for the normal function of the body's organs, including how your body responds to injury or stress. When opioids are taken for a month or longer, the medication may cause your adrenal gland to function improperly. Your doctor may monitor your adrenal gland condition especially if you have experienced stress such as surgery, injury, or severe infection.
Alcohol and other medications that cause drowsiness: Do not combine this medication with alcohol or other medications that cause drowsiness (e.g., antidepressants, sleeping pills, anxiety medications) since additive drowsiness can occur and be dangerous.
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 for 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 - guaifenesin 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: This medication can have an effect on other medical conditions. Codeine will worsen the effects of acute alcohol intoxication and delirium tremens. As well, if you have low thyroid (hypothyroidism), Addison's disease, benign prostatic hypertrophy (enlarged prostate), gallbladder disease, urethral stricture, decreased function of the adrenal glands, or porphyria, 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.
Serotonin syndrome: Although rare, severe reactions are possible when codeine is combined with other medications that act on serotonin, such as tricyclic antidepressants and serotonin reuptake inhibitors, medications used to treat depression. These combinations should be avoided if possible. Symptoms of a reaction may include muscle rigidity and spasms, difficulty moving, changes in mental state including delirium and agitation. Coma and death are possible.
If you are taking antidepressants, 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. Infants born to mothers who have been taking codeine for long periods of time or who are physically dependent on codeine will also be physically dependent on the medication and may experience breathing difficulties as well as withdrawal symptoms.
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 parent, the baby is at risk of receiving a morphine overdose through the breast milk. If you are breast-feeding and are taking codeine - triprolidine - pseudoephedrine - guaifenesin, it may affect your baby. Taking this medication while breast-feeding is not recommended.
Children: Codeine - triprolidine - pseudoephedrine - guaifenesin should not be given to children under 18 years of age.
Seniors: This medication is more likely to cause side effects for those 65 years of age and older. Lower doses may be necessary.
