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.

The TOUCH Prescribing Program is in your corner

Because TYSABRI may increase your risk of developing progressive multifocal leukoencephalopathy (PML), you can receive it only through the TOUCH® Prescribing Program.

Infusion centers, doctors’ offices, and hospitals authorized by the TOUCH program are staffed by nurses who are committed to your safety. In addition to educating you on the potential risks of TYSABRI, they are there to answer any infusion questions you make have. Before each infusion, they will also ask you a series of questions to make sure TYSABRI is still right for you.

At each infusion appointment, share any new or ongoing medical conditions such as:
  • Any new or worsening problems that have lasted several days
  • If you’ve had hives, itching, or trouble breathing during or after an infusion
  • If you’ve had a fever or infection
  • If you are taking any other medications, including prescription and nonprescription medicines, vitamins, and herbal supplements
