What is the most important information I
should know about TYSABRI?
• TYSABRI increases your chance of getting a
rare brain infection that usually causes death or
severe disability. This infection is called
progressive multifocal leukoencephalopathy
(PML). If PML happens, it usually happens in
people with weakened immune systems.
• No one can predict who will get PML.
• There is no known treatment, prevention, or cure
• Your chance of getting PML may be higher if you
are also being treated with other medicines that
can weaken your immune system, including other
treatments for Multiple Sclerosis (MS) and
Crohn’s disease (CD). Even if you use TYSABRI
alone to treat your MS or CD, you can still get
• Your chance of getting PML increases with a
longer period of treatment or if you have received
medicines that can weaken your immune system
prior to starting TYSABRI. However, PML is a rare
• TYSABRI is available only through a restricted
distribution program called the TOUCH®
Prescribing Program. In order to receive
TYSABRI, you must talk to your doctor and
understand the benefits and risks of TYSABRI
and agree to all of the instructions in the
TOUCH® Prescribing Program.
• If you take TYSABRI, it is important that you call
your doctor right away if you get any new or
worsening medical problems (such as a new or
sudden change in your thinking, eyesight,
balance, or strength or other problems) that have
lasted over several days. Tell all of your doctors
that you are getting treatment with TYSABRI.
• If you get PML, your doctor will monitor you for
certain new or worsening symptoms that can
happen suddenly after you get PML. Contact your
doctor right away if you think your general health
status is getting worse. Your doctor may
diagnose you as having Immune Reconstitution
Inflammatory Syndrome (IRIS) and treat you for
these symptoms if they happen. Failure to treat
these symptoms can lead to serious
complications or death.
