Tysabri infusions are typically given once every 28 days, which means patients usually receive an intravenous (IV) infusion once a month. This schedule is the standard dosing frequency for Tysabri, although in some cases, depending on individual circumstances and medical advice, the interval between infusions might be adjusted to every 4 or 6 weeks. The infusion itself usually takes about an hour to administer.
The reason for this monthly infusion schedule is to maintain a consistent level of the medication in the bloodstream to effectively manage multiple sclerosis (MS) symptoms and reduce disease activity. Tysabri works by targeting specific molecules involved in the immune system’s attack on the nervous system, so regular dosing helps keep this process under control.
Patients receiving Tysabri infusions are monitored closely during and after the infusion for any potential side effects or infusion reactions. These can include allergic reactions or other immune responses, so healthcare providers take precautions such as premedication and observation during the infusion session.
While the standard interval is every 28 days, some healthcare providers may tailor the timing based on how a patient responds to treatment, their risk factors, or other health considerations. This personalized approach aims to balance effectiveness with safety, minimizing risks such as infections or other complications.
In summary, Tysabri infusions are most commonly scheduled every four weeks, with each infusion lasting about an hour, but the exact timing can be adjusted by the treating physician to best suit the patient’s needs.
