Inflammatory bowel disease (IBD) is a term that includes the autoimmune conditions Crohn's disease and ulcerative colitis. It’s characterized by inflammation in the digestive tract, which can lead to symptoms such as abdominal pain, diarrhea, and weight loss.
Support for IBD varies depending on the individual, but often medications are used to manage the symptoms. One of these is Remicade (infliximab), a drug prescribed to help reduce inflammation in the digestive tract. While it can help some people, Remicade is not without side effects. Here’s what you need to know about how Remicade works, why it’s prescribed, and what natural alternatives to IBD medication are available.
What Is Remicade?
Remicade is a biologic drug (meaning it’s derived from live cells) that belongs to a class of medications called tumor necrosis factor (TNF) alpha-blockers. TNF-alpha is a signaling protein that helps regulate your immune response and drives inflammation. Remicade is given by intravenous infusion rather than being taken by mouth. (Source)
How Does Remicade Work?
Let’s take a quick step back to look at IBD. The two IBD conditions — Crohn's and ulcerative colitis — are autoimmune diseases, meaning your immune system mistakenly attacks healthy tissue. In the case of IBD, this inflammation occurs in the digestive tract. (Source)
People with IBD have increased production of TNF-alpha in the intestines, with higher amounts correlating to more inflammatory activity and disease severity. Inflammation causes symptoms such as abdominal pain and diarrhea, so Remicade blocks the action of TNF-alpha, reducing inflammation and easing symptoms (but also suppressing your immune system as a whole).

Who Is Remicade For?
Remicade has been approved for adults and children over 6 to treat Crohn's disease and ulcerative colitis (as well as several other autoimmune conditions such as rheumatoid arthritis and plaque psoriasis). It’s usually prescribed when other treatments haven’t helped. (Source)
What to Expect During a Remicade Infusion
Remicade is given through an intravenous infusion by a health care professional. The infusion takes about 2 hours, so you'll stay at the infusion center and be monitored throughout the appointment. (Source)
Follow-up visits vary depending on your care plan. Often the appointments are more frequent in the beginning but then spread farther apart for maintenance doses.
How Long Does the Remicade Infusion Take to Work?
It can take some time for Remicade to start working, although it depends on the individual. Some people see improvement within the first few days, while others take longer. And according to some research, up to 40% of patients don't respond at all to anti-TNF drugs, including Remicade. (Source)
Remicade can lose effectiveness over time, possibly because the body produces antibodies to fight the medication or because of disease progression. If this happens, your provider will often suggest increasing the dosage or switching to a different medication. (Source).
