Immunosuppressants (Anti-rejection Medicines)

There are 3 groups of anti-rejection (immunosuppressant) medications:

• Induction medicines: – a strong anti-rejection medicine given intravenously (IV) before you receive your transplant (usually in the operating room) and repeated one or more times in the days after your transplant surgery. This medicine helps get your body’s immune system ready to accept the new kidney. Your transplant team will determine the specific medicine and number of doses you need based on your personal risk for kidney rejection. 
• Maintenance medicines: anti-rejection medicines you will take for as long as you have your transplanted kidney. These medicines are started shortly after your surgery (while you are still in the hospital) and then you will be responsible for managing them long-term after your transplant. More information about these medicines is shared below.
• Rejection treatments: medicines which are used if your body starts to reject your kidney, also called a rejection episode. If you have symptoms of rejection, call your transplant team right away as this can be a medical emergency. 

Common maintenance immunosuppressants (anti-rejection medicines)

The list below is focused on the most common “maintenance medicines”. These are the medicines that need to be taken every day to help you prevent the rejection of your kidney transplant. Most patients will need a combination of medicines from this list to get the most benefit of keeping your new kidney healthy.

There are some foods that affect these medications and make them stronger or weaker, such as grapefruit and grapefruit juice. Read more about NKF's Nutrition Coach.

These medicines have been proven to help stop the body from rejecting the new kidney for many years after transplant surgery. To increase your chances of success, you should always take your anti-rejection medications as prescribed by your transplant doctor (or another member of your transplant team). This still holds true no matter how you feel or if you think your transplanted kidney is working well enough to no longer need them. 

These medicines are for life – your new kidney is depending on them! Stopping, missing, or skipping these medicines will very likely cause rejection, either right away or over time. Kidney rejection is hard to diagnose in its early stages. Rejection often cannot be stopped once it starts and results in the loss of the transplanted kidney.

Keep in mind that your anti-rejection medicines may change over time – doses may change, new medicines may be added, and/or some medicines may be stopped. It’s important to check in regularly with your transplant team and always follow your most recently updated medication list.

Anti-rejection (immunosuppressant) medicines have several possible side effects. These are usually manageable for most patients and often get better over time. Some of the most common side effects of anti-rejection (immunosuppressant) medications include:

• High blood pressure
• Diabetes
• High cholesterol
• An increased chance of having infections
• Gastrointestinal (stomach/digestive) side effects
• Increased risk of some forms of cancer

To help with side effects, you will need regular blood draw labs to check how much medicine is in your blood. If there is too much medicine, your side effects may be worse. If there isn’t enough medicine, your kidney may not be protected enough. When you first get your transplant, you will have blood draws more often. As time goes by, you will not need them as often. Even if your blood draw labs say your medicine levels are in the goal ranges, tell your transplant team about any side effects or symptoms you are feeling. Your healthcare professional may be able to change your doses and/or switch to a different medicine.

Living with daily medicines often means creating new habits so you can remember to take them in a way that fits into your routine. Talk to your transplant team if you are having trouble sticking to your medicine schedule. Some common barriers and potential solutions shared by patients include:

If a healthcare professional outside of your transplant team gives you a prescription for a new medicine, let your transplant team know right away before taking it. The same is true for any over-the-counter medicines, herbal supplements, or vitamins you are planning to take. Many medicines and supplements can interfere with your anti-rejection medicines. The combinations can sometimes stop your anti-rejection medicines from working or make the medicine level in your blood go too high and cause side effects.

Anti-rejection medicines can be expensive, but there are a lot of ways to get help paying for them. It is very important to always take your medicines as prescribed. Don’t lower your doses or stretch out doses to try and save money. This is extremely dangerous and should not be done because it can hurt your kidney and/or cause rejection. Call your transplant center’s financial coordinators and/or social workers if you are having trouble or are worried about paying for your medication. If you have Medicare, you can also reach out to a certified Medicare counselor in your state.

No insurance

If you meet the following criteria:

• had your kidney transplant at a Medicare-approved facility in the United States,
• do not have Medicaid, and
• do not have any other form of insurance, 

you may be eligible for Medicare Part B-ID to cover only your immunosuppressants. Even if you are under 65 and it has been more than three years since your transplant, lifetime Medicare coverage for immunosuppressants is available. 

Other prescription assistance programs

Some companies offer prescription assistance programs for patients on their medications to those who qualify. Visit the NKF Prescription Discount and Assistance Resources page for a list of assistance programs available for medicines that people with kidney disease and/or kidney transplant may need.
