Prednisone is a glucocorticoid medication mostly used to suppress the immune system and decrease inflammation in conditions such as asthma, COPD, and rheumatologic diseases.[3] It is also used to treat high blood calcium due to cancer and adrenal insufficiency along with other steroids.[3] It is taken by mouth.[3]

Common side effects may include cataracts, bone loss, easy bruising, muscle weakness, and thrush.[3] Other side effects include weight gain, swelling, high blood sugar, increased risk of infection, and psychosis.[4][3] It is generally considered safe in pregnancy and low doses appear to be safe while the user is breastfeeding.[5] After prolonged use, prednisone must be stopped gradually.[3]

Prednisone is a prodrug and must be converted to prednisolone by the liver before it becomes active.[6][7] Prednisolone then binds to glucocorticoid receptors, activating them and triggering changes in gene expression.[4]

Prednisone was patented in 1954 and approved for medical use in the United States in 1955.[3][8] It is on the World Health Organization's List of Essential Medicines.[9] It is available as a generic medication.[3] In 2021, it was the 28th most commonly prescribed medication in the United States, with more than 19 million prescriptions.[10][11]
