Hydrocortisone is a corticosteroid hormone produced by the adrenal glands that helps regulate various bodily functions, including metabolism and the immune response. It is commonly used in medicine as an anti-inflammatory and immunosuppressive agent to treat conditions such as Allergies, Asthma, and autoimmune disorders. Hydrocortisone can be administered topically, orally, or via injection, depending on the condition being treated. Its use may come with side effects, especially with long-term use.
