codeine - pheniramine - guaifenesin
How does the Calmylin Ace medication work? What will it do for me?
This combination product contains three medications: codeine, pheniramine, 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 cough by acting in the brain to dull the cough reflex.
Pheniramine belongs to the group of medications called antihistamines, and helps to relieve sneezing and runny nose.
Guaifenesin belongs to the group of medications called expectorants. It helps to loosen mucus so it can be coughed up.
This medication is used to control cough and to help with the removal of mucus from the chest and throat when less potent medications have been tried and have failed.
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.
What form(s) does the Calmylin Ace medication come in?
Each 5 mL of cherry-flavored, clear, orange, syrupy liquid with a menthol odour contains 100 mg of guaifenesin, 7.5 mg of pheniramine maleate and 10 mg of codeine phosphate. Nonmedicinal ingredients: alcohol, artificial coloring and flavoring, caramel, citric acid, FD&C Yellow No. 6, glycerine, menthol, propylene glycol, purified water, sodium benzoate, sodium citrate dehydrate, sodium cyclamate and sucrose. Alcohol: 4.1 % v/v. Sucrose: 45 %.
How should I use the Calmylin Ace medication?
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 and adolescents over 12 years old is 10 mL (2 teaspoonsful) every 4 to 6 hours as needed. No more than 6 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.
It is important to take this medication exactly as prescribed by your doctor. If your doctor has told you to take this medication on a regular basis and you miss a dose, take it as soon as possible and continue with your regular schedule. If it is almost time for your next dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one. If you are not sure what to do after missing a dose, contact your doctor or pharmacist for advice.
Store this medication at room temperature, protect it from light and moisture, and keep it out of the reach of children.
Do not dispose of medications in wastewater (e.g. down the sink or in the toilet) or in household garbage. Ask your pharmacist how to dispose of medications that are no longer needed or have expired.

Health Canada has issued new restrictions concerning the use of prescription codeine. To read the full Health Canada Advisory, visit Health Canada’s web site at www.hc-sc.gc.ca.
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 12 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: This medication contains sugar, which may increase blood glucose levels. It may become necessary to test your blood glucose levels more often when taking codeine – pheniramine – guaifenesin.
If you have 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: This medication may cause drowsiness. Do not drive, operate machinery, or perform other potentially hazardous tasks until you know how this medication affects you.
Glaucoma: Codeine – pheniramine – guaifenesin may make glaucoma worse. If you have narrow-angle 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 irregular heart rhythm, ischemic heart disease, high blood pressure, or another 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 function: 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 function: Acetaminophen can cause decreased liver function. If you have liver disease or reduced liver 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.
Other medical conditions: The medications in codeine – pheniramine – guaifenesin can have an effect on other medical conditions. The codeine may make symptoms of delirium tremens or acute alcohol intoxication worse.
As well, this medication may cause 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, to become worse. 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.
Seizures: If you have seizures or have a history of seizure disorders, 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 unless the benefits outweigh the risks. 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 a risk of receiving a morphine overdose through the breast milk.
If you are a breast-feeding mother and are taking codeine – pheniramine – guaifenesin, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
Children: Children may be more likely to experience severe side effects of medications for cough and cold. As a result, this medication is not recommended for children.
Seniors: Seniors may be more susceptible to the harmful effects of the medicines in this product.
