Uses For Gamimune N
Immune globulin injection belongs to a group of medicines known as immunizing agents. It is used to prevent or treat diseases that occur when your body has a weak immune system. Immune globulin contains antibodies that make your immune system stronger. It is used for patients who have primary humoral immunodeficiency (PI), idiopathic thrombocytopenic purpura (ITP), and chronic inflammatory demyelinating polyneuropathy (CIDP). It is also used as a maintenance treatment to improve muscle strength and disability in patients with multifocal motor neuropathy (MMN).
This medicine is to be administered only by or under the supervision of your doctor.
Once a medicine has been approved for marketing for a certain use, experience may show that it is also useful for other medical problems. Although these uses are not included in product labeling, immune globulin is used in certain patients with the following medical conditions:
- Chronic parvovirus B19 infection (treatment).
- Dermatomyositis (treatment).
- Guillain-Barré syndrome (treatment).
- Hyperimmunoglobulinemia E syndrome (treatment).
- Infections in low-birth-weight preterm high-risk neonates (prophylaxis and treatment adjunct).
- Lambert-Eaton myasthenic syndrome (treatment).
- Relapsing-remitting multiple sclerosis (treatment).
Before Using Gamimune N
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:
Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Appropriate studies performed to date have not demonstrated pediatric-specific problems that would limit the usefulness of immune globulin injection in children. However, safety and efficacy have not been established in children with CIDP, safety and efficacy have not been established for Flebogamma®, Gammagard Liquid to treat MMN, and subcutaneous injection of Gamunex®-C in children with PI, and safety and efficacy have not been established for Gammagard Liquid to treat PI and Vivaglobin® in children younger than 2 years of age.
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of immune globulin injection in the elderly. However, elderly patients are more likely to have age-related blood clotting problems, kidney disease, or heart disease, which may require caution for patients receiving immune globulin injection.
