Hydrocortisone, sold under a number of brand names including Cortef, is the name for the hormone cortisol when supplied as a medication.[2] Uses includes 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.[3] It can be given by mouth 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.[4] It works as an antiinflammatory and by immune suppression.[1]

Hydrocortisone was discovered in 1955.[5] It is on the World Health Organization's List of Essential Medicines, the most effective and safe medicines needed in a health system.[6] It is available as a generic medication.[1] The wholesale cost in the developing world is about 0.27 USD per day as of 2014 for the form taken by mouth.[7] In the United States it costs less than 25 USD for a typical month of treatment.[3]
