Betamethasone is a steroid medication.[3] It is used for a number of diseases including rheumatic disorders such as rheumatoid arthritis and systemic lupus erythematosus, skin diseases such as dermatitis and psoriasis, allergic conditions such as asthma and angioedema, preterm labor to speed the development of the baby's lungs, Crohn's disease, cancers such as leukemia, and along with fludrocortisone for adrenocortical insufficiency, among others.[3] It can be taken by mouth, injected into a muscle, or applied to the skin, typically in cream, lotion, or liquid forms.[3][4]
Serious side effects include an increased risk of infection, muscle weakness, severe allergic reactions, and psychosis.[3] Long-term use may cause adrenal insufficiency.[3] Stopping the medication suddenly following long-term use may be dangerous.[3] The cream commonly results in increased hair growth and skin irritation.[4] Betamethasone belongs to the glucocorticoid class of medication.[3] It is a stereoisomer of dexamethasone, the two compounds differing only in the spatial configuration of the methyl group at position 16 (see steroid nomenclature).[5]
Betamethasone was patented in 1958, and approved for medical use in the United States in 1961.[3][6] The cream and ointment are on the World Health Organization's List of Essential Medicines.[7] It is available as a generic medication.[3] In 2021, it was the 251st most commonly prescribed medication in the United States, with more than 1 million prescriptions.[8][9]
