    Treating Heart Failure With Diuretics

    Should I Avoid Certain Food or Medications While on a Diuretic?

    Diuretics are generally prescribed in combination with an ACE inhibitor, digoxin, and a beta-blocker. If you have more side effects after taking your medicines together, call your doctor. You may need to change the times you are taking each drug.

    Potassium-sparing diuretics increase the effects of digoxin and lithium. They may increase your body's potassium level if taken with ACE inhibitors.

    Before a diuretic is prescribed, tell your doctor if you are taking other drugs for high blood pressure, digoxin, Indocin, lithium, probenecid, or corticosteroids (prednisone).

    Before you’re prescribed a diuretic, tell your doctor if you have diabetes, kidney disease, liver disease, or gout.

    Follow your doctor's advice about your diet. This may include:

    • A low-salt diet
    • Taking a potassium supplement
    • Adding high-potassium foods (such as bananas and orange juice) in your diet.

    Note: Some diuretics cause your body to lose potassium. If you’re taking a "potassium-sparing" diuretic, your doctor may want you to avoid potassium-rich foods, salt substitutes, low-salt milk, and other sources of potassium. If you are not sure what type of diuretic you are taking, ask your doctor.

    Other Guidelines for Taking Diuretics

    Weigh yourself at the same time every day (on the same scale) and record your weight. Call your doctor if you gain 2 pounds in 1 day or 5 pounds in 1 week.

    While taking them, have your blood pressure and kidneys tested regularly, as advised by your doctor.

    Keep all appointments with your doctor and the lab so that your doctor can monitor your response to the medicine.

    Avoid alcohol and sleep aids. They may increase the side effects of this drug.
