Corticotropin (Injection)

Corticotrophin is administered by injection to treat multiple sclerosis and other disorders in adults and infantile spasms in babies and children.


Corticotropin is an injection that is used to treat a range of conditions in both adults and babies. In babies and infants up to the age of two, the treatment is used for the treatment of infantile spasms. In adults, it is commonly used for the treatment of multiple sclerosis. This treatment can also be used by adults in treating disorders of the joints, autoimmune diseases, skin conditions, eye conditions, lung conditions, allergies and swellings.

Corticotropin is a hormone-releasing treatment that promotes the release of corticosteroids from the adrenal gland of patients. It triggers the same response in the body that is normally triggered by stress and in doing so provides the body with the chemicals it needs to reduce the symptoms of multiple sclerosis and infantile spasms, in addition to other conditions.

This medication is only available when prescribed by a doctor and is administered as HP Acthar. The medication is injected into the patient and takes the form of a gel or jelly.

A nurse usually administers this medication in a hospital or clinic. In some cases, however, the patient may be taught to administer the treatment at home. Before doing so you should ensure that you are completely confident in knowing what you are doing to safely administer the correct dose. If you have any questions then you should consult your doctor.
