How REMICADE® Works
Your immune system works around the clock to protect you from bacteria, viruses, and other foreign agents. When you have Crohn's disease (CD) , your immune system becomes overactive and produces excess amounts of a protein called tumor necrosis factor-alpha, or TNF-alpha.
The presence of excess TNF-alpha causes your immune system to mistakenly attack healthy cells in your gastrointestinal tract. This leads to the inflammation you experience as the symptoms of CD . REMICADE® has been shown to block the action of TNF-alpha. This inhibits the underlying causes of inflammation.

REMICADE® is not right for everyone.
REMICADE® can lower your ability to fight infections. Serious and sometimes fatal events can occur. There have been reports of serious infections including tuberculosis (TB) and infections caused by bacteria, fungi, or viruses that have spread throughout the body. Lymphoma, including a fatal kind called hepatosplenic T-cell lymphoma, and other cancers have been reported in children and adults taking REMICADE®. Some people with heart failure should not take REMICADE®. Other serious side effects reported include skin cancer, hepatitis B, liver injury, blood problems, allergic reactions, nervous system problems, or lupus-like syndrome. To learn more about these and other risks, please read the Important Safety Information and the Medication Guide , and talk with your doctor.
How REMICADE® is given
REMICADE® is given as an intravenous (IV) infusion , by a healthcare professional, over a 2-hour period.
- When a medication is infused, it goes straight into the bloodstream, so it gets to work right away
- Patients may need medication before starting REMICADE® to prevent or reduce potential side effects of administration
A healthcare professional will be there during the entire treatment and for a period of time afterward:
- During the infusion, patients are not alone
- Someone is always close by to monitor for side effects
REMICADE® is the only medication of its kind to require as few as 6 treatments a year  after 3 starter doses. After that, you'll receive a dose every 8 weeks—as few as 6 a year.
