This kit contains two medications: immune globulin and hyaluronidase.

Immune globulin is used to boost the body's natural defense system against infection in persons with a weakened immune system (primary immune deficiency). Immune globulin contains natural substances called antibodies (a type called IgG) that come from healthy human blood (plasma). These antibodies help protect your body against infections and help you to fight an infection if you get sick.

Immune globulin is also used to treat a certain nerve disorder (chronic inflammatory demyelinating polyneuropathy-CIDP). This disorder causes weakness and numbness/tingling/pain in the arms and legs. This medication helps to improve these symptoms and prevents relapse.

Hyaluronidase is used to help the body absorb the immune globulin.

Read the Patient Information Leaflet and Instructions for Use if available from your pharmacist before you start using immune globulin/hyaluronidase and each time you get a refill. If you have any questions, ask your doctor or pharmacist.

This medication is given slowly by injection (infusion) under the skin in the abdomen or thigh as directed by your doctor, usually every 3 to 4 weeks. Hyaluronidase should be injected first followed by immune globulin. Do not inject this medication into a blood vessel. The dosage is based on your medical condition, weight, and response to treatment.

To reduce your risk of side effects, your doctor may direct you to start this medication at a low dose and gradually increase your dose and dosing interval. Follow your doctor's instructions carefully.

If you are using this medication at home, learn all preparation and usage instructions from your health care professional and the product package.

Let the medication vials come to room temperature before use. Do not shake the vials. Before using, check this product for particles or discoloration. If either is present, do not use the liquid. Before injecting each dose, clean the skin you are going to inject into (the injection site) with rubbing alcohol. Change the injection site(s) each time to lessen injury under the skin. Do not inject into bony areas or into skin that is infected, scarred or swollen. To lessen bruising, do not rub the injection site after each dose. Learn how to store and discard medical supplies safely.
