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.
Allergic reactions: If you have had a reaction to acetylsalicylic acid (ASA) or other NSAIDs (e.g., ibuprofen, ketoprofen, diclofenac) that included a runny nose, itchy skin rash, nasal polyps, or shortness of breath and wheezing, you should not take this medication. If you experience symptoms of a severe allergic reaction (e.g., hives; difficulty breathing; wheezing; swelling of the face, tongue, or throat), get immediate medical attention.
Bladder symptoms: This medication can cause bladder symptoms such as frequent or painful urination and blood in urine. If you develop these symptoms, stop taking this medication and contact your doctor immediately.
Drowsiness and dizziness: This medication can cause drowsiness or dizziness. Do not drive or operate machinery until you are sure that this medication does not affect your ability to do these safely.
Fluid and electrolyte balance: This medication can cause fluid retention. If you have heart failure, high blood pressure, or other medical conditions that increase your risk of fluid retention (e.g., kidney 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.
Nabumetone may also cause high blood potassium levels. If you are a senior; have diabetes or kidney failure; or are taking beta-blockers (e.g., metoprolol, atenolol), angiotensin converting enzyme (ACE) inhibitors (e.g., ramipril, enalapril), or some diuretics (e.g., triamterene, amiloride), you are more at risk of high blood potassium.
Infection: As with other anti-inflammatory medications, nabumetone may mask the usual signs of infection.
Kidney function: This medication can affect kidney function. You have a higher risk of developing kidney problems if you are a senior; take diuretics (water pills; e.g., hydrochlorothiazide, furosemide); or already have kidney disease, liver disease, or heart failure.
Your doctor may monitor your kidney function with blood tests if you take this medication. 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 problems: This medication may affect your liver function or cause liver problems. If you experience symptoms of liver problems (e.g., nausea, vomiting, feeling tired, yellowing of the skin or eyes), contact your doctor immediately. If you have liver 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.
Sun sensitivity: This medication may make your skin more sensitive to sunlight (including sunlamps) and may cause sunburn; skin blisters; and skin redness, itching, or discolouration. If you have a reaction from the sun while taking this medication, contact your doctor.
Ulcers and bleeding in the stomach and intestines: This medication can cause stomach ulcers, perforation (holes), and bleeding from the stomach. These complications can occur at any time without warning, and are sometimes severe enough to require immediate medical attention. The risk of ulcers and bleeding increases if you are taking higher doses of nabumetone for longer periods of time.
Other factors that increase the risk of these complications include drinking excessive amounts of alcohol, increased age, smoking, poor health, H. pylori infection, and taking certain medications (e.g., warfarin, ASA, clopidogrel, prednisone, citalopram, fluoxetine, paroxetine, sertraline).
If you currently have ulcers in the stomach or intestines that are bleeding, or have an inflammatory bowel disease (e.g., Crohn's disease, ulcerative colitis), you should not take this medication. If you have a history of these conditions, 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.
Stop taking the medication and get immediate medical attention if you experience symptoms or signs of stomach ulcers or bleeding in the stomach (black, tarry stools; blood in stools; stomach pain; vomiting blood or coffee grind material). These reactions can occur at any time during treatment without warning.
Vision: Blurred vision has occasionally been reported with the use of this medication. If this symptom develops, stop taking nabumetone and contact your doctor.
Pregnancy: This medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking this medication, stop taking it immediately and call your doctor. This medication must not be used during the last 3 months of pregnancy, as it may cause heart and kidney problems for the developing baby and prolonged labour with excessive bleeding during delivery.
Breast-feeding: Taking this medication while breast-feeding is not recommended since the safety of doing so has not been established.
Children: The safety and effectiveness of using this medication have not been established for children.
Seniors: Seniors appear to have a higher risk of developing side effects from this medication. The lowest effective dosage should be used under close medical supervision.
