Tysabri®

Tysabri® is a specialized prescription medication containing Natalizumab (300 mg per 15 ml vial), formulated as a concentrate for intravenous infusion. Primarily utilized as a disease-modifying therapy for neurological conditions like multiple sclerosis, this biologic agent works by restricting specific immune cells from entering the central nervous system, thereby reducing inflammation and relapses. Designed strictly for single-use intravenous administration after appropriate dilution, the product demands precise clinical handling—including instructions not to shake the solution. The packaging features standard storage guidelines to preserve sterile integrity and ensure patient safety throughout treatment.
