Infliximab is a biologic medication primarily used to treat autoimmune conditions such as rheumatoid arthritis, Crohn’s disease, ulcerative colitis, ankylosing spondylitis, psoriatic arthritis, and plaque psoriasis. It’s a monoclonal antibody that works by inhibiting tumor necrosis factor-alpha (TNF-alpha), a substance in the body that causes inflammation and is found in higher levels in people with these conditions. By blocking TNF-alpha, infliximab helps reduce inflammation, relieve symptoms, and prevent disease progression.

It’s typically administered via intravenous infusion, and the dosage and frequency depend on the specific condition being treated. As with any medication, there are potential side effects, which can range from mild, such as headaches or stomach pain, to more severe, such as increased risk of infections or infusion reactions. It’s important for patients to discuss potential risks and benefits with their healthcare provider.
