Uses of Tysabri Injection
Benefits of Tysabri Injection
Multiple sclerosis (MS) is a disease of the brain and spinal cord in which a person’s own immune system attacks the protective sheath (called myelin) of the nerves. This leads to symptoms such as vision loss, pain, fatigue and improper coordination. Tysabri 300mg Injection helps to suppress the body’s immune system, thereby reducing the progression of the disease. It reduces the inflammation of the damaged nerves, prevents further damage and stabilises your immune system. It improves muscle strength and helps the patients to walk better. This makes the patients more confident and enhances their quality of life.
