With TYSABRI, trained healthcare professionals administer your infusion every 28 days. The actual infusion takes about an hour. During your infusion, you’re welcome to listen to music, watch movies, catch up on work, read, or even just relax. For your first 12 infusions, you'll be asked to stay for an additional hour for routine observation. After your 12th infusion, your healthcare provider may decide to shorten or skip the observation period.
Because TYSABRI may increase your risk of developing progressive multifocal leukoencephalopathy (PML), you can receive it only through the TOUCH Prescribing Program.
