Before you begin taking a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should take this medication.
HEALTH CANADA ADVISORY
February 4, 2014
Health Canada has issued new restrictions concerning the use of olmesartan. To read the full Health Canada Advisory, visit Health Canada's web site at www.hc-sc.gc.ca.
Drowsiness/reduced alertness: Blood pressure medications may cause drowsiness or dizziness. Avoid driving or operating machinery until you know whether the medication affects you in this way.
Kidney disease: Olmesartan may affect the function of the kidneys, especially for those people who already have kidney problems. If you have kidney 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.
Liver disease: Liver disease may cause olmesartan to be cleared more slowly from the body, resulting in increased side effects. If you have 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.
Low blood pressure: Occasionally, a greater-than-expected drop in blood pressure occurs after taking this medication. It is more likely to occur if you are taking additional diuretics (water pills), have reduced salt intake, are on dialysis, have diarrhea, or are vomiting.
Your doctor may recommend that you have your blood pressure tested more often in these situations. To reduce the risk of dizziness, people with low blood pressure or those just starting to take this medication should stand or sit up slowly when getting up from a lying down or sitting position. If low blood pressure causes you to faint or feel lightheaded, contact your doctor.
Pregnancy: Olmesartan should not be taken during pregnancy. If you become pregnant while taking this medication, stop taking the medication and contact your doctor immediately.
Breast-feeding: It is not known if olmesartan passes into breast milk. If you are a breast-feeding mother and are taking this medication, it may affect your baby. Do not breast-feed while you are taking this medication.
Children: The safety and effectiveness of this medication have not been established for children less than 6 years of age.
