Thymoglobulin

Generic name: Antithymocyte Globulin Rabbit
Drug class: Selective immunosuppressants

Usage of Thymoglobulin

Anti-thymocyte globulin (rabbit) injection is used together with other medicines to prevent and treat the body from rejecting a transplanted kidney.

This medicine is an immunosuppressant. When a patient receives an organ transplant, the body's white blood cells will try to get rid of (reject) the transplanted organ. Anti-thymocyte globulin (rabbit) works by preventing the white blood cells from doing this.

The effect of anti-thymocyte globulin (rabbit) on the white blood cells may also reduce the body's ability to fight infections. Before you begin treatment, you and your doctor should talk about the benefits of this medicine as well as the risks of using it.

This medicine is to be given only by or under the direct supervision of your doctor.

Relate drugs

How to use Thymoglobulin

A doctor will give you this medicine in a hospital. This medicine is given through a needle placed in one of your veins. The medicine must be injected slowly, so the needle will need to stay in place for 4 to 6 hours.

This medicine is usually given for 4 to 7 days to prevent rejection of the kidney transplant. It is given for 7 to 14 days to treat rejection of the kidney transplant.

You may be given other medicines (eg, acetaminophen, steroids, allergy medicines) at least 1 hour before you receive anti-thymocyte globulin (rabbit) injection to help prevent infusion reactions.

Missed Dose

This medicine needs to be given on a fixed schedule. If you miss a dose or forget to use your medicine, call your doctor or pharmacist for instructions.

Warnings

It is very important that your doctor check your progress at regular visits to make sure that this medicine is working properly. Blood tests may be needed to check for unwanted effects.

This medicine may cause serious types of allergic reactions, including infusion reaction and anaphylaxis. These can be life-threatening and require immediate medical attention. Tell your doctor right away if you or your child start to have cough, trouble breathing, hives, itching, or skin rash, lightheadedness, dizziness, or fainting, tightness in the chest, or swelling of the face or lips.

Anti-thymocyte globulin (rabbit) can temporarily lower the number of white blood cells in your blood, increasing the chance of getting an infection. It can also lower the number of platelets, which are necessary for proper blood clotting. If this occurs, there are certain precautions you can take, especially when your blood count is low, to reduce the risk of infection or bleeding:

If you can, avoid people with infections. Check with your doctor immediately if you think you are getting an infection or if you get a fever or chills, cough or hoarseness, lower back or side pain, or painful or difficult urination.

Check with your doctor immediately if you notice any unusual bleeding or bruising, black, tarry stools, blood in urine or stools, or pinpoint red spots on your skin.

Be careful when using a regular toothbrush, dental floss, or toothpick. Your medical doctor, dentist, or nurse may recommend other ways to clean your teeth and gums. Check with your medical doctor before having any dental work done.

Do not touch your eyes or the inside of your nose unless you have just washed your hands and have not touched anything else.

Be careful not to cut yourself when you are using sharp objects such as a safety razor or fingernail or toenail cutters.

Avoid contact sports or other situations where bruising or injury could occur.

This medicine may increase your risk of getting cancer of the lymph system (lymphoma). Talk to your doctor if you have concerns about this risk.

While you are being treated with anti-thymocyte globulin (rabbit), and after you stop treatment with it, it is important to see your doctor about the immunizations (vaccinations) you should receive. Do not get any immunizations (vaccines) without your doctor's approval. Anti-thymocyte globulin (rabbit) may lower your body's resistance and there is a chance you might get the infection the vaccine is meant to prevent. In addition, you should not be around other persons living in your household who receive live virus vaccines because there is a chance they could pass the virus on to you. Some examples of live vaccines include measles, mumps, influenza (nasal flu vaccine), poliovirus (oral form), rotavirus, and rubella. Do not get close to them and do not stay in the same room with them for very long. If you have questions about this, talk to your doctor.
