What are dexamethasone injections used for, and how do they help treat inflammation? - #14796

Dexamethasone injection is a corticosteroid used to reduce inflammation and suppress the immune system in conditions like arthritis, allergies, or autoimmune diseases. Here’s a breakdown: How Does Dexamethasone Work? Suppresses the immune system: It reduces the production of inflammatory chemicals, helping to lower swelling, redness, and pain in the affected tissues. Inhibits immune cell activity, which slows down the immune response that drives inflammation. Uses of Dexamethasone Injection Joint inflammation (arthritis, bursitis). Allergic reactions (e.g., severe asthma or anaphylaxis). Autoimmune diseases (e.g., lupus). Severe inflammatory conditions like tendonitis or skin disorders. How Is It Administered? Intravenous (IV): For systemic conditions (e.g., severe allergic reactions). Intramuscular (IM): For general inflammation control. Localized injections: Directly into the affected joint or tissue for targeted inflammation relief. Onset of action: Effects can start within a few hours, with full benefits in 24–48 hours. Risks and Side Effects Short-term: May cause mood swings, insomnia, or increased blood sugar. Long-term: Prolonged use can lead to: Immune suppression (higher infection risk). Bone loss (osteoporosis). Weight gain and fluid retention. Adrenal suppression, where the body reduces its natural steroid production. User Experiences Most find dexamethasone injections effective in rapidly reducing inflammation and improving joint mobility. However, side effects like insomnia or mood changes are common. Those with long-term use risks may need to work closely with their doctor to minimize complications.
