Tysabri 300 mg

  •  prescription drug


Tysabri 300 mg is a prescription drug used in the treatment of relapsing forms of Multiple Sclerosis (MS). It’s generic name is Natalizumab & it comes in powder form (vial). The dosage is 300 mg /15 ml (20 mg per ml). Tysabri slows the worsening of symptoms common in people with MS and can decrease the number of flare-ups / relapses. It is marketed by Biogen.

Additional Information

Tysabri increases your risk of getting a rare brain infection—called progressive multifocal leukoencephalopathy (PML)—that usually leads to death or severe disability. If PML occurs, it usually occurs in people with weakened immune systems. There is no known treatment, prevention, or cure for PML.

Your risk of getting PML may be higher if you are also being treated with other medicines that can weaken your immune system, including other treatments for MS. You should not take certain medicines that weaken your immune system at the same time you are taking Tysabri. Even if you use Tysabri alone to treat your MS, you can still get PML.

Side Effects

Because Tysabri can weaken your immune system, it may increase your risk of getting an unusual or serious infection. If you also take other medicines that can weaken your immune system, you have a higher risk of getting infections.

Common side effects include headache, urinary tract infection, lung infection, pain in your arms and legs, vaginitis, stomach-area pain, feeling tired, joint pain, depression, diarrhea, rash, and nausea. If you experience any side effect that bothers you or does not go away, tell your doctor.
