HEALTH CANADA ADVISORY
February 19, 2021
Health Canada has issued new restrictions concerning the use of acetaminophen. To read the full Health Canada Advisory, visit Health Canada's web site at https://recalls-rappels.canada.ca/en/alert-recall/unintentional-exposure-young-children-adult-acetaminophen-tablets-may-pose-serious
Abdominal conditions: Oxycodone may make the diagnosis of abdominal conditions more difficult or it may worsen these conditions. People with abdominal conditions such as inflammatory or obstructive bowel disease, acute cholecystitis, or pancreatitis should discuss with their doctor how this medication may affect their medical condition, how their medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Accidental use: When oxycodone - acetaminophen is used by anyone other than the person for whom it was prescribed, the effects of the medication may be fatal. Children are especially at risk. Keep this medication out of sight and reach of children.
Alcohol and other medications that cause drowsiness: People taking this medication should not combine it with alcohol, and should avoid combining it with other medications that cause drowsiness or slow down your breathing (e.g., antidepressants, sleeping pills, anxiety medications). Doing so can cause additive drowsiness and reduced breathing, as well as other side effects, which can be dangerous and possibly fatal.
Breathing: Oxycodone can suppress breathing. People at risk for breathing difficulties, such as asthma, should discuss with their doctor how this medication may affect their medical condition, how their medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Dependence and withdrawal: This medication contains oxycodone. Physical dependence, psychological dependence, and abuse have occurred with the use of oxycodone. 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 this medication is stopped suddenly, 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: 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. These people should discuss with their doctor how this medication may affect their medical condition, how their medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Kidney function: Decreased kidney function can cause this medication to build up in the body, causing side effects. 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 severe and potentially fatal liver damage. Acetaminophen is a common ingredient in many non-prescription medications for colds and flu, pain, arthritis, and fever. Check the product label on all the medications you are taking to make sure that you are not exceeding the recommended dose of acetaminophen. An overdose of acetaminophen can lead to potentially fatal liver damage.
Contact your doctor immediately 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.
Low blood pressure: This medication can make low blood pressure worse or cause low blood pressure, which may be severe. If you experience severe dizziness, especially when standing from a lying or sitting position, contact your doctor.
Other medical conditions: People about to undergo surgery of the biliary tract should use caution while taking oxycodone as it may worsen their condition. Oxycodone will worsen the effects of acute alcohol intoxication and delirium tremens.
As well, people with an irregular heart rhythm, low blood pressure, low thyroid (hypothyroidism), Addison's disease, benign prostatic hypertrophy (enlarged prostate), urethral stricture, decreased function of the adrenal glands, or porphyria should discuss with their doctor how this medication may affect their medical condition, how their 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. 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).
Serotonin Syndrome: Although rare, severe reactions are possible when oxycodone 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 unless the benefits outweigh the risks. Infants born to mothers who have taken oxycodone during pregnancy have been born with signs of narcotic withdrawal. If you become pregnant while taking this medication, contact your doctor immediately.
Breast-feeding: This medication passes into breast milk. If you are a breast-feeding mother and are taking oxycodone and acetaminophen, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
Children: The safety and effectiveness of using full-strength oxycodone - acetaminophen have not been established for children under 18 years of age.
Seniors: Seniors who take this medication may be more likely to experience side effects or worsening of preexisting medical conditions.
