Dexamethasone 4mg Tablets

Product Introduction

Dexamethasone 4mg is an oral corticosteroid used for selected inflammatory, allergic, autoimmune and cancer-related treatment needs. It has a strong, long-acting glucocorticoid effect. The tablets are a systemic treatment and are distinct from dexamethasone injections, eye drops and local steroid preparations.

How to use

Take the tablet with food or milk to reduce stomach irritation. A once-daily regimen is commonly taken in the morning with breakfast to reduce sleep disruption. Some cancer and antiemetic regimens use a different schedule; a prolonged course may need a gradual dose reduction rather than abrupt stopping.

How it works

Dexamethasone activates intracellular glucocorticoid receptors and changes expression of genes involved in inflammation and immune responses. This reduces production of inflammatory mediators and activity of several immune cells.

Side effects

Indigestion, increased appetite, insomnia, mood changes, fluid retention and raised blood glucose may occur. Longer treatment can cause bone loss, muscle weakness, cataracts and increased infection risk. Severe infection, gastrointestinal bleeding or major psychiatric symptoms needs urgent attention.

Important information

Tell your doctor about diabetes, active or previous infections including tuberculosis, ulcers, glaucoma, osteoporosis and mood disorders. Report exposure to chickenpox or measles during immunosuppressive treatment. Live vaccines and NSAIDs need particular attention. During prolonged use, illness or surgery can require changes because the body's own cortisol production may be suppressed.
