HEALTH CANADA ADVISORY
January 31, 2019
Health Canada has issued new restrictions concerning the use of hydrochlorothiazide. To read the full Health Canada Advisory, visit Health Canada's web site at www.hc-sc.gc.ca.
Breathing problems: In general, people who have asthma and certain other breathing problems or chronic lung disease should use pindolol cautiously, as it can cause breathing difficulty. Low doses of this medication may be taken with caution by those with asthma who do not respond to or cannot tolerate alternative treatment. If you have breathing 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.
Cholesterol: Increases in cholesterol and triglyceride levels may occur when taking hydrochlorothiazide.
Diabetes: The signs of low blood sugar may not be as noticeable when taking pindolol. Hydrochlorothiazide may make it more difficult for people with diabetes to control their blood sugar. If you have diabetes, 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. It may be necessary to monitor your blood glucose levels more often when you are taking this medication. Dose adjustment of diabetes medications, including insulin, may be necessary.
Drowsiness/reduced alertness: Dizziness or fatigue may occur when starting treatment with this medication and may impair your ability to drive or operate machinery. Avoid driving, operating machinery, or performing other potentially hazardous tasks until you have determined how you are affected by this medication.
Fluid and electrolyte balance: Levels of electrolytes such as potassium, sodium, magnesium, and chloride can be reduced by the use of hydrochlorothiazide. Your doctor will periodically check to see if your electrolytes remain in balance. A potassium supplement may be necessary when taking this medication. Warning signs or symptoms of fluid and electrolyte imbalance include dryness of mouth, thirst, weakness, lethargy, drowsiness, restlessness, seizures, confusion, muscle pains or cramps, muscular fatigue, low blood pressure, racing heartbeat, and nausea and vomiting.
Gout: Hydrochlorothiazide may increase the level of uric acid in the body. If you develop painful, warm and swollen joints or difficulty with urination, contact your doctor as soon as possible.
If you have a history of gout, 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 failure: Beta-blockers, such as pindolol, can worsen existing heart failure. If you have a history of heart failure, 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
Hyperthyroidism (high level of thyroid hormones): People with hyperthyroidism should be cautious while taking pindolol as it may reduce the symptoms of this condition, giving a false impression of improvement. Stopping the medication suddenly could worsen this condition.
Kidney function: Hydrochlorothiazide may cause decreased kidney function, particularly if you already have reduced kidney function. If you have 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.
Liver function: Liver disease or reduced liver function may cause this medication to build up in the body, causing side effects. 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. Your doctor may want to test your liver function regularly with blood tests while you are taking this medication.
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, contact your doctor immediately.
Lupus: Hydrochlorothiazide may worsen the symptoms of this condition.
Severe allergies: If you experience allergies severe enough to cause anaphylaxis (a severe allergic reaction where swelling of the face, lips, and throat make it difficult to breathe), talk to your doctor about what to do if you have an allergic reaction. Pindolol may make it more difficult to treat the allergic reaction with epinephrine.
Skin conditions: Various skin rashes and dry eyes have been reported with use of other beta-blockers. Flare-ups of psoriasis have been reported by people who take pindolol - hydrochlorothiazide.
Stopping usage: This medication should not be stopped suddenly by people who have angina. There have been reports of severe worsening of angina and of heart attack or abnormal heart rhythms occurring in people with angina who have stopped this medication abruptly.
Surgery: If you are scheduled for surgery, inform all doctors involved in your care that you are taking a medication that contains pindolol.
Pregnancy: Pindolol - hydrochlorothiazide should not be taken by pregnant women. 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 pindolol - hydrochlorothiazide, 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.
