Side Effects Of Remicade (Infliximab)

Remicade (infliximab) was the first TNF-alpha (tumor necrosis factor alpha)-blocker to be approved to treat inflammatory bowel disease (IBD). TNF-alpha drugs are used to treat Crohn's disease and ulcerative colitis because people with IBD have been shown to have more TNF-alpha in their bodies than people who do not have IBD.

Remicade is given by infusion in a doctor's office, infusion center, or hospital setting. An IV is used to give the drug. The infusion typically takes a few hours, during which time the patient is monitored for adverse reactions. In certain cases, an infusion may be given more rapidly.

While it's worthwhile to be aware of potential side effects, it's also important to understand that a drug does not cause every possible side effect in every person who receives it. This is a list of side effects that have been reported by people receiving Remicade, or by their physicians. People are prescribed this medication because it's important to prevent IBD from causing inflammation in the digestive tract. The reason for this is that ongoing inflammation can lead to serious, long-term complications. If there is a side effect during an infusion, talk to the nurses in the hospital or the infusion center right away. If there is a side effect that occurs later, such as at home, be sure to discuss it with the physician who prescribed Remicade.

FDA Black Box Warning

Remicade does have what the FDA calls a Black Box Warning. This means that at the top of the patient information packet, there's some special wording in bold that's surrounded by a black box. The reason why Remicade has this special designation is because everyone who takes this drug should be tested for tuberculosis (TB) before receiving it. Another section states that anyone who has a severe infection shouldn't take the drug, or should stop taking it if an infection develops. The last part discusses the potential risks of certain types of cancers, such as skin cancers and lymphoma. This all sounds scary, but the actual risk of cancer is thought to be very low.

What follows are some of the potential side effects of Remicade. Not all adverse effects occur in all people, and some of them are very rare. Concerns about the potential for side effects should be discussed with a gastroenterologist.
