    Serious Warnings and Precautions

    You should not take PRINIVIL while you are pregnant. Taking it while you are pregnant can cause injury and even death to your baby. If you become pregnant while taking this drug, stop taking it and get in touch with your doctor as soon as possible.

    DO NOT USE PRINIVIL IF:

    • you are allergic to lisinopril or to any of the other ingredients in PRINIVIL.
    • you have had an allergic reaction (angioedema):
      • to any other ACE inhibitor. You can tell you are taking or have taken an ACE inhibitor because these types of drugs have ingredients that end with “-PRIL” (such as enalapril and captopril) or
      • have been diagnosed with hereditary angioedema. This is an increased risk of getting an allergic reaction that is passed down through your family, or
      • where the reason for it is not known
    • Signs of an allergic reaction include:
      • swelling of the hands, feet, ankles, face, lips, tongue and throat
      • suddenly having trouble breathing or swallowing
    • Make sure that you tell your doctor, nurse or pharmacist that this has happened to you before.
    • have diabetes or kidney disease and are already taking:
      • a blood pressure-lowering medicine that contains aliskiren (such as Rasilez) or
      • an angiotensin receptor blocker (drugs that have ingredients that end in “-SARTAN”).
    • Taking these drugs at the same time as PRINIVIL is not recommended.

    Low Blood Pressure:

    You may feel dizzy or light headed:

    • particularly in the first few days after you start taking PRINIVIL. You should lie down if this happens. You should avoid driving or doing any tasks that require special attention.
    • when you exercise or when the weather is hot.

    If you faint, stop taking the drug and talk to your doctor.

    Blood tests:

    While you are taking PRINIVIL your doctor may do blood tests to check:

    • the level of white blood cells in your blood.
    • the potassium levels in your blood.
    • that your kidneys are working properly.

    Cough:

    You may develop a cough while taking PRINIVIL. This usually goes away once you stop taking it or when the dose is lowered.

    Black patients:
