Liver Transplant

Medicines after your liver transplant

​​​​​​​​​​​​​​What kind of medicine will I need to take after my liver transplant?

Anti-rejection medicines (also called immunosuppression medicines) prevent your immune system from attacking the transplanted liver. Anti-rejection medicines include:

You will need to take anti-rejection medicines every day for the rest of your life. Not taking these medicines as instructed, or missing doses, may lead to your liver not working properly or not working at all.

Take these medicines at the same time of day that you took them in hospital. Never stop taking these medicines or change your dose without first talking to a member of the liver transplant team.

Always have at least a 2-week supply of medicines at home and do not run out.

When you take anti-rejection medicines:

  • You will need to get bloodwork done often to monitor your medicine levels. Your blood sample needs to be taken before you take your anti-rejection medicine.
  • Many prescription, over-the-counter, and herbal medicines can interact with your anti-rejection medicines.
  • Before you start taking a new medicine, always confirm with your pharmacist that it will not interact with your anti-rejection medicines. Notify your transplant team of any new medicine you start that is ordered by another doctor.
  • You should not take non-steroidal anti-inflammatory drugs (NSAIDs) like Advil, ibuprofen, Motrin, naproxen, and Aleve. You can use acetaminophen (Tylenol), but should not take more than 3,000 mg in 24 hours from all sources.
  • Some foods will interact with your anti-rejection medicines. Talk to the transplant team to learn more about which foods to avoid.
  • Tell your pharmacist, dentist, and all other healthcare providers that you are taking anti-rejection medicines.
  • Do not get pregnant or get someone pregnant while on anti-rejection medicines without first talking to a member of the transplant team. Ask the transplant team about using birth control, as some forms of birth control work better with anti-rejection medicines than others.
  • Anti-rejection medicines can increase your risk of some types of cancer. For more information, talk to the transplant team.

There are other medicines you might also need to take:

  • medicines to protect your stomach from ulcers caused by other medicines
  • antibiotics, antivirals, or both to help protect you against infection
  • antacids (but do not take antacids within 2 hours of taking any anti-rejection medicines)
  • water pill (also known as a diuretic) to help your body remove extra fluid
  • medicines to keep up with essential nutrients like calcium, magnesium, or iron
  • medicines to prevent pneumocystis pneumonia, including sulfamethoxazole-trimethoprim, atovaquone, or pentamidine (common brand names of these medicines are Septra, Bactrim, Co-Trimoxazole, and Mepron)
  • medicines to prevent or treat cytomegalovirus (CMV), including valganciclovir (common brand name: Valcyte)
  • medicines to prevent or treat herpes virus infections, including valacyclovir (common brand name: Valtrex)
  • medicines to prevent or treat fungal infections

The following table is a general guide about common transplant medicines.

Medicine
Reason for taking
tacrolimus, sirolimus, cyclosporine anti-rejection
​mycophenolate mofetil anti-rejection
​Septra, Bactrim, or alternatives such as atovaquone or pentamidine

prevent pneumocystis pneumonia

valganciclovir prevent CMV infection
valacyclovir prevent herpes virus infection
nystatin prevent thrush
​aspirin or other anti-clotting medicine prevent clots in your liver artery or vein

You are responsible for taking your medicines. Talk to your transplant team to understand:
  • the name and reason for each medicine
  • when to take each medicine
  • how to take each medicine
  • how to store each medicine
  • side effects of each medicine
  • what to do if you forget to take a dose
  • when to order more medicine so it doesn’t run out

Your healthcare team will teach you about your medicines while you are in the hospital. While in hospital, you will start giving yourself the medicines with directions from the nurses. This will help you become familiar with the number of new medicines you will need to take at home by yourself.

​​​​​​​​​​​​How long will I need to take medicines after my surgery?

You will need to take anti-rejection medicines every day for the rest of your life. Not taking these medicines as instructed, or missing doses, may lead to your liver not working properly or not working at all.

Talk to your transplant team if you have any questions about how long you’ll need to take each medicine.

​​​​​​​​​​​​Is the cost of transplant medicines covered by Alberta Health?

Funding for high cost transplant medicine (like tacrolimus, sirolimus, cyclosporine, and mycophenolate mofetil) is available to Alberta residents through the Specialized High Cost Drug Program. Ask your healthcare team for a list of pharmacies that participate in this program.

The Specialized High Cost Drug Program provides funding for some high cost medicines, but you may still need to pay for, or have separate insurance coverage for, some of your other non-transplant medicines, like antibiotics or pain medicine.

If you are not a resident of Alberta, you may need to pay for your medicines or check your own insurance coverage for them.​​
