Uses of Tysabri Injection

Benefits of Tysabri Injection

Multiple sclerosis (MS)
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.

Side effects of Tysabri Injection

Most side effects do not require any medical attention and disappear as your body adjusts to the medicine. Consult your doctor if they persist or if you’re worried about them

How to use Tysabri Injection

How Tysabri Injection works

Certain immune cells (T cells) are known to attack the protective sheath (myelin) around the nerves and cause disabling effects in multiple sclerosis. Tysabri 300mg Injection works by binding to T cells and preventing their entry into the brain and spinal cord. This slows disease progression and reduces the number of attacks in multiple sclerosis.

Quick tips

  • Tysabri 300mg Injection is used to treat multiple sclerosis.
  • It is given once every 4 weeks, as a drip into a vein (by intravenous infusion), usually in your arm.
  • It may increase your risk of getting infections. Inform your doctor immediately if you get any signs of infection such as fever, sore throat, mouth ulcers, rash or severe diarrhea while taking this medicine.
  • Inform your doctor if you develop symptoms of liver damage such as abdominal pain, loss of appetite, darkened urine or yellowing of the eyes or skin.
  • Do not stop treatment without talking to your doctor. You are more likely to experience an allergic reaction if you restart treatment after a gap of three or more months.
