How is immune globulin given?


Immune globulin subcutaneous is given as an injection using an infusion pump. The medicine enters the body through a needle or catheter placed under your skin. The catheter is attached to the pump with an infusion tube.

Immune globulin must be given slowly, and the infusion can take about 1 hour to complete. You may need to use up to 4 catheters to inject this medicine into different body areas at the same time. Your care provider will show you the best places on your body to inject the medication. Follow your doctor's instructions.


Subcutaneous immune globulin is for injection only under the skin. Do not inject this medicine into a vein. Before injecting the medicine, test to make sure the needle is not in a vein. To do this, gently pull back on the plunger of the syringe connected to the infusion tube. If blood flows back into the syringe, remove the catheter and tubing and throw them away. Start over with a new catheter and syringe, insert the needle in a new place on your body, and test for blood flow-back again.
