HEALTH CANADA ADVISORY
July 31, 2020
Health Canada has issued new information concerning the use of non-prescription pain relief products containing 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 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: Accidental ingestion or use of this medication by someone for whom it has not been prescribed can lead to a fatal overdose. Children are especially at risk. Keep this medication out of sight and reach of children.
Alcohol and other medications that cause drowsiness: Do not combine this medication with alcohol or other medications (e.g., antidepressants, sleeping pills, anxiety medications) that cause drowsiness since additional drowsiness or suppressed breathing can occur and be dangerous and possibly life-threatening.
Breathing: Codeine can suppress breathing. If you are at risk for breathing difficulties (e.g., if you have asthma or chronic lung 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.
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.
Drowsiness/reduced alertness: This medication may cause drowsiness. Do not drive, operate machinery, or perform other potentially hazardous tasks until you have determined how this medication affects you.
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 your 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.
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. Taking too much acetaminophen with codeine may cause liver problems.
If you experience symptoms of liver problems such as fatigue, feeling unwell, loss of appetite, nausea, yellowing of the skin or whites of the eyes, dark urine, pale stools, abdominal pain or swelling, and itchy skin, contact your doctor immediately.
Low blood pressure: Codeine may cause low blood pressure or make low blood pressure worse. If you experience severe dizziness, especially when standing from a lying or sitting position, contact your doctor.
Other medical conditions: If you are about to undergo surgery of the biliary tract, approach taking codeine with caution, as it may worsen your condition. 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.
Ultra-rapid codeine metabolizers: Some people process codeine faster and more completely than others due to a genetic variation. This can result in higher-than-expected drug levels in the body, which may result in overdose symptoms and serious or life-threatening effects on breathing. If you are known to be a rapid metabolizer of codeine you should avoid using this medication.
Worsening symptoms: If redness or swelling occurs in the area of pain, if symptoms do not improve or they worsen, or if new symptoms develop (e.g., high fever, rash, itching, persistent headache) while you are taking this medication, contact your doctor as soon as possible. These may be signs of other conditions that require medical attention.
Seizures: This medication may cause seizures. Seizures are more likely to occur when higher doses of this medication are taken. If you have a history of epilepsy or medical conditions that increase the risk of seizures, 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). Symptoms of a reaction may include muscle rigidity and spasms, difficulty moving, or 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 unless the benefits outweigh the risks. 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 may experience dangerous withdrawal symptoms at birth.
Breast-feeding: Acetaminophen, codeine, and caffeine pass 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 breast-feeding and are taking this medication, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
Children: The safety and effectiveness of using this medication have not been established for children under 12 years old. Medications containing codeine should not be given to people under 18 years old for pain management after surgery to remove the tonsils and or adenoids.
Non-prescription products containing codeine should not be used by people under 18 years old. Recent evidence shows that young people who use opioids, including codeine, may be more likely to have problems with the misuse of medications and other substances later in life.
Seniors: Seniors who take this medication may be more likely to experience side effects or worsening of preexisting medical conditions.
