Tysabri Medication Information
Available by prescription only, Tysabri® (natalizumab) is used in the treatment of multiple sclerosis (MS) or Crohn's disease when other treatments have been unsuccessful. Clinical studies have shown that this drug can help slow down the worsening of disability and reduce the number of relapses (times when symptoms flare up) in people with MS. It can also help treat and reduce symptoms in people with moderate-to-severe Crohn's disease.
Tysabri is given as an intravenous (IV) infusion. It is administered by your healthcare provider once every four weeks. Because this medication is not appropriate for everyone, your healthcare provider will need certain information from you before beginning treatment with Tysabri. Some of this information includes a list of all medical conditions you have (including allergies) and all other medicines, vitamins, and supplements you are currently taking.
Possible side effects of this drug include headaches, fatigue, and nausea. However, most people tolerate it well. If reactions do occur, they tend to be mild and easily treated.
