TYSABRI is a brand that offers a prescription medicine called natalizumab, which is used to treat relapsing forms of multiple sclerosis (MS). With over 15 years of experience, TYSABRI has empowered individuals to take control of their relapsing MS, a condition that affects people differently. In clinical studies, TYSABRI has shown to have a significant impact on relapsing MS in multiple ways.

It can slow down disability progression, with 83% of patients experiencing no progression compared to those on a placebo. Additionally, TYSABRI reduces the number of relapses by 67% and decreases the formation of new brain lesions, which are indicators of disease activity. TYSABRI is known for its power to help individuals manage their condition, but it's important to be aware that it does come with safety considerations.

It increases the risk of progressive multifocal leukoencephalopathy (PML), a rare brain infection. However, when the expected benefits outweigh the risks, TYSABRI can be a powerful choice for those with relapsing MS
