Van-Losartan-HCTZ: Uses, Side Effects and Dosage

ABOUT THIS MEDICATION

What the medication is used for:

• VAN-Losartan-HCTZ lowers high blood pressure.

What it does:

VAN-Losartan-HCTZ contains 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 VAN-Losartan-HCTZ regularly even if you feel fine.

When it should not be used:

Do not take VAN-Losartan-HCTZ if you:

• are allergic to VAN-Losartan-HCTZ or any of the

  non-medicinal ingredients in the formulation.

• are allergic to any sulfonamide-derived drugs (sulfa

  drugs); most of them have a medicinal ingredient that ends in “-MIDE”.

• have experienced an allergic reaction (angioedema)

  with swelling of the hands, feet, or ankles, face, lips, tongue, throat, or sudden difficulty breathing or swallowing to any ARB. Be sure to tell your doctor, nurse, or pharmacist that this has happened to you.

• Have been diagnosed with hereditary angioedema:

  an increased risk of getting an allergic reaction that is passed down through families. This can be triggered by different factors, such as surgery, flu, or dental procedures.

• have difficulty urinating or produce no urine.

  • are already taking a blood pressure-lowering medicine that contains aliskiren (such as Rasilez) and you have diabetes or kidney disease.

  • are pregnant or intend to become pregnant. Taking

    VAN-Losartan-HCTZ during pregnancy can cause injury and even death to your baby.

    • Galactose intolerance
    • Lapp lactase deficiency
    • Glucose-galactose malabsorption Because lactose is a non-medicinal ingredient in VAN-Losartan-HCTZ tablets.
