What is the dosage for infliximab?

Infliximab is administered intravenously. The recommended dose is a 5 mg/kg infusion at 0, 2, and 6 weeks and then 5 mg/kg every 8 weeks for moderate to severe active Crohn's disease or fistulizing Crohn's disease in adult or pediatric patients. Adults who initially responded then lost response may be treated with 10 mg/kg.

The recommended dose for the treatment of moderately to severely active rheumatoid arthritis is 3 mg/kg at 0, 2, and 6 weeks followed by 3 mg/kg every 8 weeks. Infliximab should be combined with methotrexate. If response is incomplete, up to 10 mg/kg or treating every 4 weeks may be tried.

Ulcerative colitis, psoriatic arthritis, and plaque psoriasis are treated with a 5 mg/kg infusion at 0, 2, and 6 weeks and then 5 mg/kg every 8 weeks.

Ankylosing spondylitis is treated with a 5 mg/kg infusion at 0, 2, and 6 weeks then 5 mg/kg every 6 weeks.

Which drugs or supplements interact with infliximab?

Because infliximab may reduce the response of the immune system, it should not be administered with vaccines containing live bacteria or viruses. Combining infliximab with anakinra (Kineret), abatacept (Orencia) or tocilizumab (Actemra), drugs that also reduce the response of the immune system, may increase the risk of serious infections.
