Infliximab is a medication used to treat various autoimmune diseases, including rheumatoid arthritis, Crohn's disease, and ulcerative colitis. It is a type of biologic therapy that works by blocking a protein called tumor necrosis factor-alpha (TNF-alpha), which plays a key role in inflammation. By inhibiting this protein, Infliximab helps reduce inflammation and alleviate symptoms associated with these conditions. Administered through an intravenous infusion, Infliximab is typically given in a healthcare setting. Patients may receive it at regular intervals, depending on their specific condition and response to treatment. While it can be effective, it may also have side effects, including an increased risk of infections, so monitoring by a healthcare provider is essential.
