Summary Reports
Consumer Information
This information was provided by the drug’s manufacturer when this drug product was approved for sale in Canada. It is designed for consumers and care givers. It is a summary of information about the drug and will not tell you everything about the drug. Contact your doctor or pharmacist if you have any questions about the drug.
What the medication is used for

What it does
LOSARTAN/HCTZ contain a combination of 2 drugs, losartan component and hydrochlorothiazide:
- Losartan component is an angiotensin receptor blocker (ARB). You can recognize an ARB because its medicinal ingredient ends in “-SARTAN”. It lowers blood pressure.
- Hydrochlorothiazide is a diuretic or “water pill” that increases urination. This lowers blood pressure.
This medicine does not cure high blood pressure. It helps to control it. Therefore, it is important to continue taking LOSARTAN/HCTZ regularly even if you feel fine.

Do not take LOSARTAN/HCTZ if you:
- are allergic to losartan potassium and hydrochlorothiazide or any of the non-medicinal ingredients in the formulation;
