Corticosteroid
A powerful anti-inflammatory medication similar to cortisol (a hormone naturally produced by the body) that can be injected into joints to quickly reduce swelling and pain.
Extended Definition
Corticosteroids, often simply called “steroids” in medical contexts (not to be confused with anabolic steroids used for muscle building), are synthetic versions of cortisol, a hormone your adrenal glands produce naturally. When injected into a joint, these medications can provide rapid and significant relief from inflammation and pain.
Common corticosteroids used for joint injections include triamcinolone, methylprednisolone, and betamethasone. These medications work by suppressing the immune system’s inflammatory response in the joint, reducing swelling, warmth, and pain. Many patients experience relief within a few days of injection, and effects can last from several weeks to several months.
While corticosteroid injections can be highly effective for managing acute joint pain flares, they are typically limited to 3-4 injections per joint per year. This is because frequent use may potentially contribute to cartilage breakdown and other side effects. They are often used as part of a comprehensive treatment plan that includes physical therapy, exercise, and other interventions. Corticosteroids are particularly useful for managing sudden increases in joint pain or when inflammation with joint swelling (effusion) is present.
