This leaflet provides important information about treatment with Atgam. You should also speak to your doctor or pharmacist if you would like further information or if you have any concerns or questions about using Atgam.

Where to find information in this leaflet:

Atgam contains the active ingredient, equine antithymocyte immunoglobulin (a type of horse protein used to help control your body's immune system response to foreign protein).

Atgam is used after a kidney transplant to stop your body's immune system from rejecting the new kidney.

Your doctor may prescribe Atgam for another purpose.

Do not use Atgam if you are allergic to Atgam/equine antithymocyte immunoglobulin or other horse proteins (equine gamma globulins) or any of the ingredients listed at the end of this leaflet.

Before being treated with Atgam, your doctor usually will do a skin test to see if you are likely to have an allergic reaction to Atgam.

It is possible for products developed from horse or human blood to carry infectious diseases like viral hepatitis and AIDS.

During treatment, you may be at risk of developing certain side effects. It is important you understand these risks and how to monitor for them. See additional information under Section 6. Are there any side effects?

Tell your doctor if you are pregnant or intend to become pregnant, are breastfeeding or intend to breastfeed. Your doctor will discuss the risks and benefits to you and your baby.

There has been limited use of Atgam in children. It has been safely used in a small number of children who have had kidney, liver or bone marrow transplants and aplastic anaemia (anaemia due to the absence of bone marrow).

Tell your doctor or pharmacist if you are taking any other medicines, including any medicines, vitamins or supplements that you buy without a prescription from your pharmacy, supermarket or health food shop.

Check with your doctor or pharmacist if you are not sure about what medicines, vitamins or supplements you are taking and if these affect Atgam.

Your doctor will decide what dose of Atgam you need and when you should start treatment with Atgam.

Your doctor will usually give you other medicines when you are given Atgam. These medicines are also used to reduce your immune response to the new kidney.

Atgam will be given under medical supervision so an overdose is unlikely.

Keep follow up appointments with your doctor or clinic.
