Remicade is a medication used to treat various autoimmune diseases, including rheumatoid arthritis, Crohn's disease, and ulcerative colitis. It works by blocking a protein called tumor necrosis factor-alpha (TNF-alpha), which plays a key role in inflammation. By inhibiting this protein, Remicade helps reduce symptoms and improve the quality of life for patients. Administered through an intravenous infusion, Remicade is typically given in a healthcare setting. Patients may require multiple doses over time, depending on their specific condition and response to treatment. Like all medications, it can have side effects, so monitoring by a healthcare professional is essential.
