Hydrocortisone is widely used in the medical field for its anti-inflammatory and immunosuppressive properties. It is commonly applied topically to treat skin conditions such as eczema, dermatitis, insect bites, and rashes, reducing redness, swelling, and itching. In its oral or injectable form, it is used to manage severe allergic reactions, asthma, arthritis, and autoimmune diseases like lupus. Additionally, it plays a critical role in treating adrenal insufficiency, a condition where the body cannot produce sufficient cortisol. Hydrocortisone is also utilized in emergency settings to address anaphylactic shock and other life-threatening inflammatory conditions. Its ability to modulate the immune response makes it a versatile and essential medication in both chronic and acute care.
