If you have
heart failure, you need to be extra careful with
medicines. Some can make your heart failure worse. Other medicines may not mix
well with your heart failure drugs.

This Actionset will help you
learn which medicines you may need to avoid and what questions to ask your
doctor or pharmacist.

  • Each time you see a doctor, make sure he or she
    knows that you take medicines for heart failure.
  • Before you fill
    any new prescription, tell the pharmacist that you have heart failure. Ask if
    it’s okay to take the new prescription medicine.
  • Before you take
    over-the-counter medicine, such as a cold or flu
    remedy, ask your doctor or a pharmacist if it is safe to take it with your
    heart failure medicines.
  • Tell each doctor about all the other
    medicines you take. This includes over-the-counter medicines, such as cold and
    flu remedies, herbal products, and natural supplements and vitamins. Take a
    list of your medicines or bring your medicines to each doctor’s
  • Whether or not some medicines will make your heart
    failure worse depends on how severe your heart failure is. It also depends on
    what type of heart failure you have.

How do you know if your other medicines are safe to take with your heart failure medicines?

Talk to your doctor or a pharmacist.
Show him or her a list of all the medicines you take.

Be organized

It’s important to keep an up-to-date
list of your medicines. Here are some tips:

  • Make a list of everything you take. Keep a
    copy in your purse or wallet, and take it to each doctor or hospital visit.
    Anytime you see a new doctor, show him or her your list.
  • Remember
    to include herbs, vitamins, and over-the-counter medicines on your
  • Have each doctor keep a copy of your list of medicines in
    your file.
  • Make sure your spouse, a family member, your
    caregiver, or a friend has an extra copy of your list of
  • Use the same pharmacy or drugstore for all of your
  • Update your list if you start a new medicine or
    stop taking one.

Ask questions

What if you need to take a medicine
that can make heart failure worse? Here are some things you can do:

  • Ask your doctor or a pharmacist if it is safe
    to take the medicine.

    • For example, if you have a cold or the
      flu, ask which medicine is safe to take.
    • Ask how long you should
      take the medicine and how much you should take. It may be safe to take it for a
      short time.

Watch for problems

Call your doctor if you have new or changed symptoms, such as:

  • New or increased shortness of breath.
  • New or worse swelling in your legs, ankles, or feet.
  • Sudden weight gain, such as
    more than 2 lb (0.9 kg) to 3 lb (1.4 kg) in a day or 5 lb (2.3 kg) in a week. (Your doctor may suggest a different range of weight gain.)
  • Feeling dizzy or lightheaded or like you may faint.
  • Feeling so tired or weak that you cannot do your usual activities.
  • Not sleeping well. Shortness of breath wakes you at night. You need extra pillows to prop yourself up to breathe easier.

Over-the-counter medicines you may need to avoid

Pain relievers called NSAIDs

  • Ibuprofen, such as Advil and Motrin
  • Naproxen, such as Aleve
  • Aspirin, such as Bayer
    • If you take an aspirin every day for other heart problems, ask your doctor if it’s safe for
      you. Aspirin can help prevent blood clots that could cause a heart attack or stroke.
    • Higher doses of aspirin may make your heart failure
      worse. Do not take aspirin for pain, such as from headaches or arthritis. Use
      acetaminophen, such as Tylenol, instead.

Cold, cough, flu, or sinus medicines

  • Be sure to check the label. Do not take
    medicines that contain pseudoephedrine, ephedrine, phenylephrine, or
    oxymetazoline, such as:

    • Sudafed.
    • Nose sprays
      (decongestants), such as Afrin and Dristan.
    • Herbal remedies, such
      as ma huang and Herbalife.
  • Make sure your cough and cold medicines
    don’t contain aspirin or ibuprofen.

Antacids or laxatives that contain sodium

  • Check the label for sodium or saline. Examples include:
    • Antacids, such as Alka-Seltzer.
    • Laxatives, such as Fleet Phospho-Soda.

Dietary supplements

  • Dietary supplements include herbal medicines and natural products. Before you take
    a supplement, ask your doctor or a pharmacist if it is safe for you. Examples include:

    • Black cohosh.
    • St. John’s wort.
    • Vitamin E.
