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 report, visit Health Canada's website 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.
Allergy: Some people who are allergic to other anti-inflammatory medications or those who have nasal polyps or asthma also experience allergic reactions to ASA. Before you take ASA - caffeine - codeine - butalbital, inform your doctor about any previous adverse reactions you have had to medications, especially non-steroidal anti-inflammatory medications or narcotic medications. Contact your doctor at once if you experience signs of an allergic reaction, such as skin rash, itching, difficulty breathing or swelling of the face and throat.
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 and butalbital 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 and butalbital. Physical dependence, psychological dependence, and abuse have occurred with the use of both these medications. 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.
If you have been taking this medication regularly and suddenly stop taking it, 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 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.
Kidney function: Taking ASA - caffeine - codeine - butalbital 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, 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.
Medication overuse headaches: When medications are taken regularly for some types of headaches, medication overuse headaches may develop. These are sometimes called "rebound headaches." The symptoms of the headache return as the effects of the medication wear off. This is a symptom of the body "withdrawing" from the medication, a result of taking the medication too frequently. If you experience more headaches than usual or notice that the headache regularly returns after 8 hours, contact your doctor.
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 - butalbital 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. If you become pregnant while taking this medication, contact your doctor immediately.
Breast-feeding: ASA - caffeine - codeine - butalbital 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, which could be fatal. This medication should not be used by breast-feeding mothers.
Children: The safety and effectiveness of using this medication have not been established for children under the age of 18 years.
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.
Seniors: Seniors may be more susceptible to the harmful effects of the medicines in this product.
What other drugs could interact with this medication?
There may be an interaction between ASA - caffeine - codeine - butalbital and any of the following:
If you are taking any of these medications, speak with your doctor or pharmacist. Depending on your specific circumstances, your doctor may want you to:
An interaction between two medications does not always mean that you must stop taking one of them. Speak to your doctor about how any drug interactions are being managed or should be managed.
Medications other than those listed above may interact with this medication. Tell your doctor or prescriber about all prescription, over-the-counter (non-prescription), and herbal medications you are taking. Also tell them about any supplements you take. Since caffeine, alcohol, the nicotine from cigarettes, or street drugs can affect the action of many medications, you should let your prescriber know if you use them.
