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 any 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 appointment.
- 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.
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 list.
- 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 medicines.
- Use the same pharmacy or drugstore for all of your prescriptions.
- Update your list if you start a new medicine or stop taking one.
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 1 kg (2 lb) to 1.3 kg (3 lb) in a day or 2 kg (5 lb) in a week. (Your doctor may suggest a different range of weight gain.)
- Feeling dizzy or light-headed 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.
