Hizentra drug: Uses, indications and precautions when using

This is an automatically translated article.

Immunoglobulins contain natural substances called antibodies (a type called IgG) that come from healthy human blood. These antibodies help protect your body against infection and help you fight infection if you get sick. Some immunoglobulin products may also be used to treat a certain nerve disorder (chronic polyneuritis - CIDP).

Before using Hizentra, tell your doctor if you are allergic to this product; or other immunoglobulin products with any other allergies if any. Hizentra products may contain inactive ingredients (such as polysorbate 80) and they may cause allergic reactions or other problems.

Some immunoglobulin products are made from maltose. This substance can cause falsely high blood sugar when your blood sugar is normal or even low. If you have diabetes, check with your pharmacist whether the product you are using contains maltose and whether your blood sugar test kits are suitable for this product. Rarely, serious problems can occur when too much insulin is injected due to a falsely high blood sugar reading or when low blood sugar is left untreated.
Tell your doctor about any recent or planned immunizations/vaccinations. Hizentra can prevent a good response to some live attenuated vaccines (such as measles, mumps, rubella varicella). If you have recently received any of these vaccines, your doctor may order a reaction test or you will get the vaccine again later.
