Dexamethasone tablets, as a corticosteroid medication, have main functions and effects summarized as follows:

1. Anti-inflammatory action: Dexamethasone can inhibit the production and release of various inflammatory mediators, reduce vascular permeability in inflamed areas, and alleviate inflammatory symptoms such as redness, swelling, heat, and pain. It is suitable for various acute or chronic inflammatory diseases, such as rheumatoid arthritis, systemic lupus erythematosus, and nephrotic syndrome.

2. Immunosuppressive action: By inhibiting lymphocyte proliferation and function, reducing antibody production, and suppressing immune responses, dexamethasone is used in the treatment of autoimmune diseases such as myasthenia gravis and multiple sclerosis.

3. Anti-allergic action: Dexamethasone stabilizes mast cell membranes and reduces the release of allergic mediators like histamine, making it useful for controlling allergic reactions such as allergic rhinitis and asthma.

Long-term or high-dose use may lead to a series of adverse reactions, such as central obesity, moon face, acne, and edema. It may also induce or exacerbate conditions like ulcers, diabetes, and osteoporosis. Therefore, patients should closely monitor changes in their symptoms during the use of dexamethasone tablets, and seek medical attention promptly if adverse reactions occur.
