What is Olumiant?

Olumiant (baricitinib) blocks the activity of certain enzymes involved in activating inflammation in the body.

Olumiant is used to reduce pain, stiffness, and swelling in adults with rheumatoid arthritis after other treatments have failed.

Olumiant also helps slow the progression of bone and joint damage.

Olumiant is also being studied for use in treating coronavirus. The US Food and Drug Administration (FDA) has authorized emergency use of Olumiant to treat adults and children at least 2 years old who are hospitalized with COVID-19 and using supplemental oxygen or a ventilator. Olumiant has not been approved to treat coronavirus or COVID-19.
