acetaminophen - codeine
How does this medication work? What will it do for me?
This combination product contains two medications: acetaminophen and codeine. Acetaminophen belongs to the group of medications called analgesics (pain relievers) and antipyretics (fever reducers). Codeine belongs to the family of medications known as opioid analgesics (narcotic pain relievers). This medication is used to relieve moderate to severe pain.
Codeine works by acting on the central nervous system to block pain signals, increasing the ability to tolerate pain. Acetaminophen works by raising your pain threshold.
This medication may be available under multiple brand names and/or in several different forms.

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.

What form(s) does this medication come in?

How should I use this medication?
Acetaminophen with codeine comes in a variety of different strengths and dosage forms. Dosing depends on the strength and dosage form being used.
Tablets: The recommended adult dose is 1 tablet every 4 to 6 hours as needed for pain. No more than 6 tablets should be taken in a 24 hour period.
Liquid: The recommended adult dose is 10 mL to 20 mL every 4 hours as needed for pain. No more than 5 doses should be taken in a 24 hour period. For children, the recommended dose is based on body weight and is given every 4 hours as needed for pain.
Use an oral syringe to measure each dose of the liquid, as it gives a more accurate measurement than household teaspoons.

HEALTH CANADA ADVISORY
August 24, 2020
Health Canada has issued new restrictions concerning the use of acetaminophen – codeine. To read the full Health Canada Advisory, visit Health Canada’s web site at www.hc-sc.gc.ca.
Abdominal conditions: Codeine may make the diagnosis of abdominal conditions more difficult or it may worsen these conditions. If you have any abdominal conditions 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.
Alcoholism: People who drink large amounts of alcohol over long periods of time and who take this medication should be closely monitored by their doctors. These people are at increased risk of liver damage or disease.
Breathing: Codeine can suppress breathing. If you are at risk for breathing difficulties (e.g., if you have 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.
Dependence: After prolonged use, codeine can produce psychological dependence (a psychological "need" for the medication that is not related to the physical need; this is rare), physical dependence (stopping the medication abruptly may lead to withdrawal symptoms), or tolerance (the need to take higher doses to get the same effect). 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. Talk to your doctor if you have any concerns about dependence.
Drowsiness/reduced alertness: Acetaminophen – codeine may impair the mental or physical abilities required for the performance of potentially hazardous tasks such as driving a car or operating machinery. You should avoid such activities until you are certain this medication does not have this effect on you.
Head injury: People with head injuries or increased pressure in the head may have a higher risk of experiencing side effects (breathing problems) or worsening of their condition while taking this medication. If you have had a recent head injury, 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 severely reduced kidney function or kidney 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.
Liver function: If you have severely reduced liver function or 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: If you have hypothyroidism, Addison’s disease, enlarged prostate (BPH; benign prostatic hypertrophy), or narrowing of the urethra, 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: This medication may cause seizures, especially when higher doses are used or when taken with other medications that may increase the risk of seizures such as:
- monoamine oxidase inhibitors (MAOIs; e.g., phenelzine, tranylcypromine)
- neuroleptics (e.g., haloperidol, quetiapine, olanzapine, risperidone)
- opioids (e.g., fentanyl, morphine, oxycodone)
- selective serotonin reuptake inhibitors (SSRIs; e.g., paroxetine, fluoxetine, citalopram)
- tricyclic antidepressants (TCAs; e.g., amitriptyline, imipramine)
The risk of seizures is also higher for people with epilepsy, a history of seizures, or who are at risk of seizures (e.g., people with head trauma).
Pregnancy: Dependence and withdrawal signs have been reported in newborns whose mothers took medications such as acetaminophen – codeine regularly during 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: Acetaminophen and codeine pass into breast milk. Babies who are breast-fed by mothers who metabolize codeine very quickly may be at increased risk for codeine overdose because there may be higher-than-expected levels of codeine in breast milk. The safety of this medication has not been established for use by breast-feeding mothers and is not recommended for use while breast-feeding.
Children: The tablet and caplet form of this medication should not be given to children less than 12 years of age. The liquid form of the medication should not be given to children under 2 years of age.
Seniors: Seniors may be more sensitive to the side effects of this medication.
