# Nulojix

Generic name: belatacept [ bel-AT-a-sept ]
Drug class: Selective immunosuppressants

Medically reviewed by Drugs.com. Last updated on Feb 21, 2022.

## What is Nulojix?

Nulojix weakens your body's immune system, to help keep it from "rejecting" a transplanted organ such as a kidney. Organ rejection happens when the immune system treats the new organ as an invader and attacks it.

Nulojix is used with other medicines to prevent organ rejection after a kidney transplant.

Nulojix is given only to people who have been exposed to the Epstein-Barr virus (your doctor will test your blood to confirm this).

## Warnings

You should not use Nulojix if you have received a liver transplant. Before you start treatment, your doctor will perform tests to make sure you are immune to Epstein-Barr virus (EBV-positive). Your risk of serious infection is higher if you have never been exposed to EBV.

Nulojix may cause your body to overproduce white blood cells. This can lead to cancer, severe brain infection causing disability or death, or a viral infection causing kidney transplant failure.

Call your doctor right away if you have: fever, swollen glands, flu symptoms, night sweats, weight loss, vomiting, diarrhea, burning when you urinate, blood in your urine, a new skin lesion, any change in your mental state, decreased vision, weakness on one side of your body, problems with speech or walking, or pain around your transplant.

## Before taking this medicine

You should not be treated with Nulojix if you are allergic to belatacept, or if you've never been exposed to Epstein-Barr virus.

Talk with your doctor about the risks and benefits of using this medicine. Nulojix can affect your immune system, and may cause overproduction of certain white blood cells. This can lead to cancer, severe brain infection causing disability or death, or a viral infection causing kidney transplant failure.

Tell your doctor if you have ever had:

- a liver transplant;

- cytomegalovirus (CMV); or

- if you are scheduled to receive any vaccine.

It is not known whether Nulojix will harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant.

If you are pregnant, or you are a man and your sex partner is pregnant, your name may be listed on a pregnancy registry. This is to track the outcome of the pregnancy and to evaluate any effects of belatacept on the baby.

You should not breast-feed while you are using Nulojix.

## How is Nulojix given?

Nulojix is given as an infusion into a vein. A healthcare provider will give you this injection.

The injection must be given slowly, and the IV infusion can take up at least 30 minutes to complete.

Nulojix is usually given just before your kidney transplant, and again 5 days later, followed by once every 2 to 4 weeks. Follow your doctor's dosing instructions very carefully.

Belatacept can increase your risk of infection by changing the way your immune system works. You will need frequent medical tests.
