What Is Dexamethasone 4mg?

Dexamethasone is a corticosteroid, a lab-made version of hormones your adrenal glands produce naturally. It works by reducing inflammation and suppressing immune system activity that causes swelling, pain, and allergic responses. The 4mg tablet is a higher-strength option often used for short courses during flares of inflammatory or allergic conditions. It is available only with a prescription and should be taken exactly as directed, since dose and duration vary widely by condition.
