Hydrocortisone Injections: Uses, Dosage, Side Effects, Safety, and Frequently Asked Questions

What Are Hydrocortisone Injections?

Hydrocortisone injections are prescription medicines containing hydrocortisone, a corticosteroid used to reduce inflammation, control immune reactions, and replace natural steroid hormones when the body does not produce enough.

Hydrocortisone is a synthetic version of cortisol, a hormone normally produced by the adrenal glands. Injectable hydrocortisone may be given in hospitals, clinics, or specialist settings depending on the medical condition being treated.

It may be administered by:

• Intravenous (IV) injection.
• Intramuscular (IM) injection.
• Other medically appropriate routes depending on the formulation.

How Hydrocortisone Injections Work

Inflammation and immune reactions involve the release of chemicals that cause swelling, redness, pain, and tissue irritation.

Hydrocortisone works by:

• Reducing inflammatory responses.
• Suppressing excessive immune system activity.
• Decreasing the release of inflammation-causing substances.
• Helping control allergic and autoimmune reactions.
• Replacing cortisol when the body cannot produce enough.
