It is very important that your doctor check you closely 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 anaphylaxis. Anaphylaxis can be life-threatening and requires immediate medical attention. Tell your doctor right away if you have a rash, itching, trouble breathing, trouble swallowing, or any swelling of your hands, face, or mouth after you receive the medicine.

Blood clotting problems may occur while you are receiving this medicine. This is more likely to occur if you are an elderly, or if you have a history of atherosclerosis (hardening of the fats in the arteries), heart and blood vessel problems, bleeding problems, or prolonged time of not standing up or sitting down. Tell your doctor right away if you have chest pain, trouble breathing, numbness or weakness in your arm or leg, or on one side of your body, trouble seeing or speaking, or sudden or severe headache.

This medicine is made from donated human blood. Some human blood products have transmitted viruses to people who have received them, although the risk is low. Human donors and donated blood are both tested for viruses to keep the transmission risk low. Talk with your doctor about this risk if you are concerned.

While you are being treated with varicella-zoster immune globulin, do not have any immunizations (vaccinations) without your doctor's approval. Live virus vaccines (e.g., measles, mumps, rubella, varicella) should not be given within 3 months after receiving this medicine.
