HEALTH CANADA ADVISORY
June 8, 2021
Health Canada has issued new information concerning the use of non-steroidal anti-inflammatory drugs (NSAIDs). To read the full Health Canada Advisory, visit Health Canada's web site at www.hc-sc.gc.ca.
A previous advisory on ASA - caffeine - codeine - butalbital was issued on July 31, 2020.
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.
Bleeding disorders: ASA may increase bruising and bleeding from cuts that may take longer to stop. If you have a bleeding disorder or a history of bleeding problems, 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. 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.
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.
Gout: ASA may cause or worsen attacks of gout. Symptoms of an acute gout attack include sudden pain, swelling, and stiffness in the affected joint, often the big toe. You may also experience a fever. If this is your first attack, seek medical attention as soon as possible. If you have had gout attacks before, follow your doctor's instructions for dealing with the attack.
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: Taking ASA - caffeine - codeine over a long period of time may increase the risk of developing 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 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: If you are about to undergo surgery of the biliary tract, taking codeine may worsen your condition. It will also 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.
Stomach problems: ASA may cause stomach problems such as ulcers or bleeding. If you have a stomach problem, 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. Call your doctor immediately if you notice signs such as stomach or abdominal pain, black tarry stools, or vomiting blood. Using ASA at the same time as other anti-inflammatory medications increases the risk of stomach ulcers and bleeding.
Surgery: ASA may cause increased bleeding during surgery. Do not take ASA - caffeine - codeine for 5 to 7 days before any surgery, including dental surgery, unless otherwise directed by your doctor or dentist. If you are scheduled for surgery, let your doctor know that you are taking this medication.
Pregnancy: This medication is not recommended for use by pregnant women unless the anticipated benefits outweigh the possible risks.
ASA taken near the end of pregnancy increases the risk of bleeding during delivery. Regular use of codeine by pregnant women may cause withdrawal symptoms in the newborn.
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 ASA - caffeine - codeine, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
Children: The use of ASA may be associated with the development of Reye's syndrome in children and teenagers who have illnesses accompanied by fever, especially influenza and chickenpox. ASA should not be given to, or used by, children or teenagers who have chickenpox or flu symptoms unless a doctor is consulted.
Children are especially susceptible to an overdose of caffeine and its side effects on the central nervous system. ASA is one of the most frequent causes of accidental poisoning in toddlers and infants. Medications that contain ASA should be kept out of the reach of all children. This medication is not recommended for children less than 12 years of age.
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 may be at greater risk of side effects from this medication.
