  • Remicade is given by a healthcare provider by intravenous infusion (infusion into a vein) over a period of at least 2 hours. 

  • There are potential serious side effects associated with this medication, so familiarize yourself with possible side effects and be alert to symptoms that may signal a serious side effect.

  • Keep all appointments for your infusions as well as follow-up appointments with your healthcare provider and appointments for bloodwork

What are common Remicade doses?

The dose varies by indication and weight: 

  • Crohn’s disease (adults): 5 mg/kg by IV infusion at 0, 2, and 6 weeks. Then, 5 mg/kg is given every 8 weeks. For individuals who respond to treatment, but then stop responding, a higher dose of 10 mg/kg every 8 weeks may be required.

  • Crohn’s disease (pediatric patients 6 years and older): 5 mg/kg by IV infusion at 0, 2, and 6 weeks. Then, 5 mg/kg is given every 8 weeks.

How to take Remicade

  • Before you take Remicade, your healthcare provider will test you to make sure you do not have an infection.

This medicine must be given slowly, over a period of at least 2 hours. You will be watched closely after your infusion, to make sure you do not have any serious reactions.

  • A nurse or other health provider will give you this medicine.
