Hydrocortisone is a type of corticosteroid medicine used to reduce inflammation, swelling, and allergic reactions. It is widely used for skin conditions, allergies, and certain medical disorders.
Hydrocortisone can be applied directly on the skin (topical form), taken orally (pills), or injected, depending on the condition being treated.
What is Hydrocortisone?
Hydrocortisone is a synthetic version of the natural hormone cortisol, which is produced by the adrenal glands. Cortisol helps the body respond to stress, regulate metabolism, and control inflammation.
By giving hydrocortisone as a medicine, it can reduce inflammation, itching, and allergic reactions, and help the body manage conditions where cortisol levels are low.
Forms of Hydrocortisone
Hydrocortisone comes in several forms:
- Topical creams or ointments: For skin rashes, eczema, or insect bites.
- Tablets or oral forms: For hormone replacement or inflammation.
- Injections: For severe allergic reactions or adrenal insufficiency.
- Suppositories or enemas: For inflammation in the rectum or colon.
Common Uses of Hydrocortisone
Hydrocortisone is used for a variety of conditions, including:
- Skin Conditions: Eczema, dermatitis, rashes, insect bites, and allergic skin reactions.
- Allergic Reactions: Reduces swelling, itching, and redness caused by allergies.
- Adrenal Insufficiency: Replaces cortisol in people whose adrenal glands are not producing enough hormones.
- Inflammatory Conditions: Arthritis, ulcerative colitis, or other inflammatory disorders.
- Eye and Ear Problems: Certain forms are used for eye inflammation or ear infections.
How Hydrocortisone Works
Hydrocortisone works by reducing the activity of the immune system in areas where there is inflammation. It blocks chemicals in the body that cause swelling, redness, and irritation.
In skin conditions, topical hydrocortisone reduces itching and redness, helping the skin heal faster.
