About this Medication

What the Medication Is Used For

ACCURETIC lowers high blood pressure.

What It Does

ACCURETIC contains a combination of 2 drugs, quinapril hydrochloride and hydrochlorothiazide:

  • Quinapril hydrochloride is an angiotensin converting enzyme (ACE) inhibitor. You can recognize ACE inhibitors because their medicinal ingredient ends in “PRIL”. 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 ACCURETIC regularly even if you feel fine.

When It Should not be Used

Do not take ACCURETIC if you:

  • Are allergic to quinapril hydrochloride or hydrochlorothiazide or to any 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 ACE inhibitor or without a known cause. 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 pregnant or intend to become pregnant. Taking ACCURETIC during pregnancy can cause injury and even death to your baby
  • Are breastfeeding. ACCURETIC passes into breast milk.
  • Are taking aliskiren-containing medicines, such as Rasilez, and have one of the following conditions:
    • Diabetes
    • Kidney disease
    • High levels of potassium
    • Congestive heart failure combined with hypotension.
  • Are taking an angiotensin receptor blocker (ARB), another medicine to treat your high blood pressure, or another ACE inhibitor and have one of the following conditions:
    • Diabetes with end organ damage
    • Kidney disease
    • High levels of potassium
    • Congestive heart failure combined with hypotension.

You can recognize ARBs because their medicinal ingredient ends in “-SARTAN”.

  • Have one of the following rare hereditary diseases:
    • Galactose intolerance
    • Lapp lactase deficiency
    • Glucose-galactose malabsorption

    Because lactose is a non-medicinal ingredient in ACCURETIC.
