About Acthar

What is this medication? Acthar, also known as Acthar Gel, is a prescription medication that consists of repository corticotropin injection. It is an injectable hormone that works by stimulating the adrenal glands to produce natural corticosteroids, which help the body manage inflammation and immune system activity. One of its primary indications is for the treatment of infantile spasms in children under the age of two, where it serves as a specialized therapy to control certain types of seizures.

Beyond its use in infants, Acthar is also utilized to treat a wide range of inflammatory and autoimmune conditions in adults. It is frequently prescribed to manage acute exacerbations of multiple sclerosis and to treat symptoms associated with systemic lupus erythematosus, rheumatoid arthritis, and psoriatic arthritis. Additionally, it can be used for the treatment of nephrotic syndrome and respiratory conditions like sarcoidosis. By mimicking the action of natural hormones, the drug helps to suppress overactive immune responses and reduce swelling throughout the body.
