Baricitinib Lilly is used to treat adults with moderate to severe rheumatoid arthritis, an inflammatory disease of the joints, if previous therapy did not work well enough or was not tolerated. Baricitinib Lilly can be used alone or together with some other medicines, such as methotrexate.

Baricitinib Lilly works by reducing the activity of an enzyme in the body called ‘Janus kinase’, which is involved in inflammation. By reducing the activity of this enzyme, Baricitinib Lilly helps to reduce pain, stiffness and swelling in your joints, tiredness, and helps to slow damage to the bone and cartilage in the joints. These effects can help you to do normal daily activities and so improve the health-related quality of life for patients with rheumatoid arthritis.

Baricitinib Lilly is used to treat children from the age of 2 years, adolescents and adults with moderate to severe atopic dermatitis, also known as atopic eczema. Baricitinib Lilly may be used with eczema medicines that you apply to the skin or it may be used on its own.

Baricitinib Lilly works by reducing the activity of an enzyme in the body called ‘Janus kinase’, which is involved in inflammation. By reducing the activity of this enzyme, Baricitinib Lilly helps to improve the condition of your skin and reduce itching. In addition, Baricitinib Lilly helps improve your sleep disturbance (due to itch) and overall quality of life. Baricitinib Lilly has also been shown to improve symptoms of skin pain, anxiety, and depression associated with atopic dermatitis.

Baricitinib Lilly is used to treat adults with severe alopecia areata, an autoimmune disease characterized by inflammatory, nonscarring hair loss on the scalp, face and sometimes on other areas of the body that can be recurrent and progressive.

Baricitinib Lilly works by reducing the activity of an enzyme in the body called ‘Janus kinase’, which is involved in inflammation. By reducing the activity of this enzyme, Baricitinib Lilly helps hair to regrow on scalp, face and other areas of the body impacted by the disease.
