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 non-steroidal anti-inflammatory drugs (NSAIDs) was issued on October 30, 2020.
Allergy: Some people who are allergic to other nonsteroidal anti-inflammatory drugs (NSAIDs) or ASA also experience allergic reactions to ibuprofen. Before you take methocarbamol - ibuprofen, inform your doctor about any previous adverse reactions you have had to medications, especially NSAIDs. People who have experienced difficulty breathing after taking ASA or other NSAIDs should not take methocarbamol - ibuprofen.
Aseptic meningitis: Some NSAIDs such as ibuprofen can cause symptoms of aseptic meningitis (e.g., stiff neck, severe headache, nausea, vomiting, fever, decreased level of consciousness). If you experience these symptoms, contact your doctor immediately.
People with an autoimmune disorder, such as lupus or mixed connective tissue disease, are also at higher risk of developing symptoms of aseptic meningitis. If you have an autoimmune disorder, 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.
Bladder problems: NSAIDs such as ibuprofen can cause bladder problems. Stop taking this medication and contact your doctor if you experience bladder pain, difficulty urinating, frequent urination, or blood in the urine.
Bleeding disorders: NSAIDs such as ibuprofen may increase bruising, and bleeding from cuts may take longer to stop. If you have bleeding disorders, a history of bleeding problems, or are taking medications to prevent clotting, 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.
Blood pressure: Ibuprofen may cause an increase in blood pressure, even when there have been no blood pressure problems in the past. If you have high blood pressure, 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. Report any ongoing increase in blood pressure to your doctor as soon as possible.
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.
Blurred vision: If you experience blurred vision while taking this medication, stop taking it and contact your doctor.
Fluid retention and high potassium levels: NSAIDs such as ibuprofen can cause fluid retention and high blood potassium levels. If you have a history of heart failure, high blood pressure, diabetes, or kidney failure, are a senior, or are also taking beta-blockers (e.g., atenolol, metoprolol) or angiotensin converting enzyme (ACE) inhibitors (e.g., ramipril, enalapril, lisinopril), 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.
Heart attack and stroke: High doses of ibuprofen taken for prolonged periods of time have been linked to increased risk of heart attack and stroke. If you have had a heart attack or stroke, or are at risk of a heart attack or stroke, 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.
Infection: This medication may mask the signs of an infection. If you experience symptoms of an infection (e.g., fever, sore throat), contact your doctor as soon as possible.
Kidney function: Long-term use of products that contain ibuprofen may increase the risk of developing reduced kidney function. This risk is increased for people who already have kidney disease, liver disease, or heart failure; for people who are taking certain medications (e.g., beta-adrenergic blockers, angiotensin converting enzyme [ACE] inhibitors, angiotensin-II receptor antagonists, cyclosporine, or some diuretics [water pills]); and for seniors. Your doctor will monitor your kidney function with blood tests during long-term therapy with ibuprofen.
Liver function: NSAIDs such as ibuprofen can cause reduced liver function or make existing liver problems worse. If you have 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.
If you experience symptoms of liver problems such as fatigue, nausea, vomiting, stomach pain, yellowing of the skin or eyes, pale stools, dark urine, stop taking this medication and contact your doctor. If you are taking this medication for a long period of time, your doctor will monitor your liver function.
Stomach and intestines: Ibuprofen can cause stomach and duodenal ulcers and bleeding. You may have an increased risk for these problems if you have a history of stomach or duodenal ulcer, if you smoke, drink excessive amounts of alcohol, are a senior, are a woman, or are also taking oral steroids (e.g., prednisone) or anticoagulants (e.g., warfarin). Stop taking this medication and contact your doctor immediately if you experience persistent heartburn; stomach pain; vomit that looks like coffee grinds; or black, tarry, or bloody stools.
Systemic lupus erythematosus (SLE): People with SLE appear to be at a greater risk of experiencing severe adverse reactions to ibuprofen, including anaphylaxis. This medication is not recommended for people with SLE.
Pregnancy: There is not enough information to determine whether using methocarbamol - ibuprofen is safe 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: Ibuprofen passes into breast milk. It is not known if methocarbamol passes into breast milk. If you are a breast-feeding mother and are taking methocarbamol - ibuprofen, 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.
Seniors: Seniors are more likely to experience side effects with this medication and may require lower doses.
