Dexamethasone 4 mg contains a moderate dose of the synthetic corticosteroid dexamethasone, a potent anti-inflammatory and immunosuppressive medicine. Doctors prescribe this medicine to manage allergic reactions, asthma flare-ups, arthritis, autoimmune diseases and certain cancers because it reduces swelling, redness and overactive immune responses. It is also used as part of chemotherapy regimens, for cerebral edema to reduce brain swelling, and to prevent nausea and vomiting associated with chemotherapy. Its long duration of action allows once-daily dosing in most cases.

Patients taking Dexamethasone 4mg should follow a healthcare provider’s instructions closely. The tablet is usually taken with food or milk to protect the stomach. The dose may vary depending on the condition; some courses last only a few days while others taper gradually over weeks. Abruptly stopping corticosteroids can lead to adrenal insufficiency, so never discontinue without medical guidance. During treatment, maintain a balanced diet, monitor blood pressure and blood sugar if you have diabetes, and report any unusual symptoms.

Side effects of dexamethasone are generally dose-dependent. Short-term use can cause mood changes, increased appetite, trouble sleeping and fluid retention. Prolonged treatment may lead to weight gain, osteoporosis, muscle weakness, elevated blood sugar, high blood pressure and increased susceptibility to infections. To minimize these risks, the smallest effective dose for the shortest duration is recommended. Inform your doctor about all medications you take, as dexamethasone can interact with blood thinners, vaccines and certain antibiotics. Women who are pregnant, breastfeeding or planning pregnancy should discuss the benefits and risks before starting therapy.
