Patient Medication Information: uses, side effects, how to take - Telmisartan-HCTZ

ABOUT THIS MEDICATION

What the medication is used for:

Telmisartan-HCTZ is a combination of 2 drugs. It is used when 2 drugs are required to treat your high blood pressure.

What it does:

Telmisartan-HCTZ contains a combination of 2 drugs, telmisartan and hydrochlorothiazide:

  • Telmisartan 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 Telmisartan-HCTZ regularly even if you feel fine.

When it should not be used:

Do not take Telmisartan-HCTZ if you:

  • Are allergic to telmisartan, hydrochlorothiazide or to

    any non-medical ingredient in the formulation.

  • Are allergic to any sulfonamide-derived drugs (sulfa

    drugs), most of them have a medicinal ingredient that ends in “-MIDE”. This includes other diuretics (“water pills”).

  • 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 (any drug in the same class as telmisartan). Be sure to tell your doctor, nurse, or pharmacist that this has happened to you.

  • Have difficulty urinating or produce no urine
  • Are pregnant or intend to become pregnant. Taking

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

  • Are breastfeeding. Telmisartan-HCTZ passes into

    breast milk.

  • Are allergic to some sugars (lactose).
  • Are already taking a blood pressure-lowering

    medicine that contains aliskiren and you have diabetes or kidney disease.

  • Have one of the following rare hereditary diseases:

    • Galactose intolerance;

      • Lapp lactase deficiency;
      • Glucose-galactose malabsorption.

Because lactose is a non-medicinal ingredient in Telmisartan-HCTZ.

What the medicinal ingredients are:

Telmisartan and hydrochlorothiazide

What the non-medicinal ingredients are:

Citric acid monohydrate, crospovidone, iron oxide yellow (for 80 mg/25 mg tablet only), lactose anhydrous, lactose monohydrate, macrogol poly (vinyl alcohol) grafted copolymer (polyvinyl alcohol, polyethylene glycol, anhydrous colloidal silica), magnesium stearate, meglumine, povidone, sodium hydroxide.

What dosage forms it comes in:

Tablets 80 mg/12.5 mg and 80 mg/25 mg.
