  • Talk with your doctor if you are having problems with when to take your medicine. Your doctor may be able to change your medicines or the times you take them.
  • Talk with your doctor if you have any changes in your health that might affect your heart failure, such as weight gain, side effects of medicines, or another health problem.
  • Use tools like daily or weekly pill boxes to make taking your medicines simpler.

How can you take your medicines properly?

Here's how you can get started on taking your medicines properly.

Make a medicine plan

Talk with your doctor about:

  1. What medicines you take. Find out what each medicine does. If you understand what you are taking, it may be easier to follow your schedule. Write down both the brand name and generic name for your medicines. Have your doctor check the list. You can use this list to make sure that the medicines you get from the drugstore are correct.
  2. Your medicine schedule. Be sure you understand how much of each medicine to take and when to take each one. Ask your doctor if you can make your pill schedule simpler. You may be able to substitute longer-acting medicines for shorter-acting ones. Longer-acting, once-a-day medicines are easier to remember to take.
  3. How to handle missed doses. Talk with your doctor about what you should do if you accidentally miss a dose of a medicine. Discuss what to do for each medicine, because it may be different for each one.
  4. Your medicine costs. Ask your doctor if you can take generic medicines that cost less than brand names. Compare prices between several drugstores, and think about buying your medicines by mail.
  5. Medicines to avoid. You may need to avoid certain medicines. Many nonprescription medicines, prescription medicines, and natural supplements can make symptoms of heart failure worse. Or they may react with your heart failure medicines. Ask your doctor or pharmacist about medicines that may make heart failure symptoms worse, and write down those that you should not take. Check with your doctor before you take any medicines on this list.
  6. Tests to monitor your medicine. You may have regular blood tests to monitor how the medicine is working in your body. You may have to test to check how much medicine is in your body. Your doctor will likely let you know when you need to have the tests. Your doctor wants to be sure that your medicine isn't harming you and that you're getting the right dose.

Get organized

Taking medicines properly means taking the right dose of the right medicine at the right time.

  1. Make a list of all your medicines. Make a master list of all your medicines and keep it up to date. At every visit with your doctor, review this list.
  2. Plan a daily schedule of medicines. Make a daily planner that has spaces for hourly entries . Post this schedule near your medicine cabinet. Take it along when you travel.
  3. Use a pillbox that holds a week's worth of pills. This may be most helpful if you are taking pills every other day.
  4. Post reminders. Get sticky notes and write reminders to take your medicines. Post them near clocks or on the bathroom mirror to keep you on schedule.
  5. Store medicines properly. Keeping medicines in a place that is too hot or too cold may keep them from working right. Ask your doctor or pharmacist how to store your medicines. Always keep them out of the reach of children.

Watch for side effects

  • Ask your doctor or pharmacist about what side effects to expect.
  • Be sure to tell your doctor right away if you have problems from your medicines.
  • Always check with your doctor before you take any other medicines, whether they are prescription or nonprescription. This includes any herbal or "natural" supplements.
  • Let your doctor know if you have any changes in your health that might affect your heart failure, such as weight gain or another health problem.
