Acthar is a prescription medicine to be used as a short-term, add-on therapy in the event of symptoms suddenly worsening (flare) for rheumatoid arthritis, including juvenile rheumatoid arthritis. Some cases may require maintenance therapy.

How Acthar Is Believed to Work*

Acthar contains the hormone ACTH, which stands for adrenocorticotropic (“a-DRE-no-cor-ti-co-TRO-pic”) hormone.

  • Acthar is believed to work directly with your immune system
  • Acthar is also thought to have certain anti-inflammatory properties
  • Acthar is not a steroid, but one of the ways it is thought to work is by helping your body produce its own natural steroid hormones

*While the exact way that Acthar works in the body is unknown, further studies are being conducted. This information is based on laboratory data, and how it relates to patient benefit is unknown.
