About NATALIZUMAB
NATALIZUMAB belongs to the class of monoclonal antibodies. It is used in the treatment of multiple sclerosis (a condition in which the immune system attacks the protective covering of the nerves called myelin, causing disrupted communication between the brain and body) and moderately to severe Crohn’s disease (a chronic bowel disease that affects any part of the gastrointestinal tract, mainly small and large intestine) in patients who are unable to tolerate conventional Crohn’s disease therapy and inhibitors of TNF-α.
NATALIZUMAB consists of Natalizumab, which belongs to the class of integrin receptor antagonists. It works by binding to the chemical substance called α4β7 integrin (present on the surface of the WBC that enters the gut), which is responsible for inflammation.
NATALIZUMAB may cause certain side effects, such as nausea, headache, fever, joint pain, upper respiratory tract infections, abdominal discomfort, diarrhoea, tiredness, back pain, itching, depression, and injection site reactions. Most of these side effects do not require medical attention. However, if these side effects persist, please consult your doctor. NATALIZUMAB will be administered by a trained healthcare doctor. Hence, do not self-administer.
NATALIZUMAB should be avoided if you are allergic to any of its components. Inform your doctor if you have any history of serious infections, tuberculosis, liver or kidney diseases, or a weak immune system, as it can worsen your health condition. NATALIZUMAB is contraindicated in patients with Progressive Multifocal Leukoencephalopathy (PML), as it can cause serious adverse effects. Consult the doctor if you are pregnant or breastfeeding.

Medicinal Benefits
NATALIZUMAB consists of Natalizumab, which belongs to the class of integrin receptor antagonists. It works by binding to the chemical substance called α4β7 integrin (present on the surface of the WBC that enters the gut), which is responsible for inflammation. This causes inhibition and alters the gene expression of blood monocytes and thus helps reduce inflammation of the bowel disease. It is used in the treatment of moderately to severe Crohn’s disease and multiple sclerosis.

Patients Concern
Disease/Condition Glossary
Multiple sclerosis: Multiple sclerosis is a condition that affects the brain and spinal cord. The immune system attacks the protective covering of the nerves (myelin) and causes disrupted communication between the brain and body due to nerve damage. This causes symptoms such as problems with sensation, balance, vision, pain, impaired coordination, and fatigue.
Crohn’s disease: Crohn’s disease is a type of chronic inflammatory bowel disease that can affect any part of the gastrointestinal tract, from mouth to anus. But mostly occurs in the small intestine and large intestine. The symptoms include blood in stools, stomach cramps, tiredness, diarrhoea, fever, weight loss, or loss of appetite.
