Hydrocortisone is the name for the hormone cortisol when supplied as a medication.[4] Uses include conditions such as adrenocortical insufficiency, adrenogenital syndrome, high blood calcium, thyroiditis, rheumatoid arthritis, dermatitis, asthma, and COPD.[1] It is the treatment of choice for adrenocortical insufficiency.[5] It can be given by mouth, topically, or by injection.[1] Stopping treatment after long-term use should be done slowly.[1]

Side effects may include mood changes, increased risk of infection, and swelling.[1] With long-term use common side effects include osteoporosis, upset stomach, physical weakness, easy bruising, and yeast infections.[1] While used, it is unclear if it is safe during pregnancy.[6] Hydrocortisone is a glucocorticoid and works as an anti-inflammatory and by immune suppression.[1]

Hydrocortisone was patented in 1936 and approved for medical use in 1941.[7][8] It is on the World Health Organization's List of Essential Medicines.[9] It is available as a generic medication.[1] The wholesale cost in the developing world is about US$0.27 per day as of 2014 for the form taken by mouth.[10] In the United States, it costs less than US$25 for a typical month of treatment.[5] In 2017, it was the 154th most commonly prescribed medication in the United States, with more than four million prescriptions.[11][12]

Medical uses

Hydrocortisone is the pharmaceutical term for cortisol used in oral administration, intravenous injection, or topical application. It is used as an immunosuppressive drug, given by injection in the treatment of severe allergic reactions such as anaphylaxis and angioedema, in place of prednisolone in patients needing steroid treatment but unable to take oral medication, and perioperatively in patients on long-term steroid treatment to prevent an adrenal crisis. It may also be injected into inflamed joints resulting from diseases such as gout.

It may be used topically for allergic rashes, eczema, psoriasis, itching and other inflammatory skin conditions. Topical hydrocortisone creams and ointments are available in most countries without prescription in strengths ranging from 0.05% to 2.5% (depending on local regulations) with stronger forms available by prescription only. Covering the skin after application increases the absorption and effect. Such enhancement is sometimes prescribed, but otherwise should be avoided to prevent overdose and systemic impact.


The defined daily dose is 30 mg.[3] The typical dose in adults for allergies or inflammation is 100 to 500 mg by injection.[2] For those age 6 to 12 the dose is 100 mg, while in those 1 to 5 it is 50 mg and in those less than 1 year old it is 25 mg.[2] It can be given three to four times per day.[2]

The dose for severe COVID19 is 50 mg intravenously three times per day for 7 to 10 days.[13]



Hydrocortisone is a corticosteroid, acting specifically as both a glucocorticoid and as a mineralocorticoid. That is, it is an agonist of the glucocorticoid and mineralocorticoid receptors.

Hydrocortisone has low potency relative to synthetic corticosteroids. Compared to hydrocortisone, prednisolone is about 4 times as potent and dexamethasone about 40 times as potent in terms of anti-inflammatory effect.[14] Prednisolone can also be used as cortisol replacement, and at replacement dose levels (rather than anti-inflammatory levels), prednisolone is about eight times more potent than cortisol.[15]


Most cortisol in the blood (all but about 4%) is bound to proteins, including corticosteroid binding globulin (CBG) and serum albumin. Free cortisol passes easily through cellular membranes, where it interacts with corticosteroid receptors.[16]


Hydrocortisone, also known as 11β,17α,21-trihydroxypregn-4-ene-3,20-dione, is a naturally occurring pregnane steroid.[17][18] A variety of hydrocortisone esters exist and have been marketed for medical use.[17][18]
