Your body has a natural defense called the immune system that fights off things like bacteria and viruses to keep you from getting sick.

When you get a kidney transplant, your immune system may think your new kidney is a foreign invader and try to attack it. This is called organ rejection.

Immunosuppressants (im-you-no-soo-pres-ants) are a type of medicine that keep your immune system from attacking or hurting your new kidney.

Antirejection medicines, like immunosuppressants, work better when used in combination. Most patients will be on more than one antirejection medicine at the same time. These medicines work to keep your new kidney healthy. Your healthcare team will work with you to find the best medicines to keep your new kidney strong. It is important that you take your medicine as prescribed.

Do immunosuppressants have side effects?

Yes. Your immunosuppressants will have side effects, like all medicines. Be sure to review the Medication Guides that came with your prescriptions for important safety information.

According to the American Society of Transplantation, tacrolimus (the active ingredient in ENVARSUS XR) can cause different side effects if there is too much or too little in your system.

Too much tacrolimus in your system can lead to:

  • Decreased kidney function
  • Tremors and shakiness
  • Headache
  • Trouble sleeping
  • High potassium levels
  • Low magnesium levels

Too little tacrolimus in your system can lead to:

  • Rejection of your transplanted kidney

Side effects that are not related to the level of tacrolimus in your system include:

  • High blood pressure
  • High blood sugar
  • Tingling in hands and feet
  • Hair loss or hair thinning

Your healthcare team can prescribe you medicine to help treat these side effects. For instance, if your blood pressure is too high, your healthcare team might prescribe you a medicine to help lower your blood pressure.

According to the American Society of Transplantation, people who receive a kidney transplant have a high risk of getting infections. This is because of the immunosuppressants they will be taking. Your healthcare team may prescribe you medicine to help keep you from getting sick from certain infections caused by bacteria, viruses, and fungi.

If you are having side effects, talk with your doctor as soon as possible to find out if a different treatment may be better for you.

Do I have to keep taking immunosuppressants?immuno-suppressants?

Yes. The American Society of Transplantation recommends you take your medicine every day, exactly as your healthcare team has instructed. Missing even just one dose can cause your body to reject your new kidney. If you have any trouble affording the cost of your medicine, talk to your healthcare team about how you can pay for it. Never stop taking your medicine without talking to your healthcare team first.

How do I remember to take all these pills?

There are many methods you can use to remember to take your medicine. The National Kidney Foundation recommends these simple techniques:
