What is Olumiant (baricitinib)?
Olumiant contains the prescription medicine baricitinib. Olumiant is used to reduce the symptoms of severe rheumatoid arthritis, such as pain, stiffness, and joint swelling. It helps to reduce joint and bone damage from getting worse. Olumiant may also be used for the treatment of severe alopecia areata in adults. Olumiant is used where other medication has been tried and failed, or you can not tolerate the side effects of the other medication. Using Olumiant in combination with other JAK inhibitors, biological disease-modifying antirheumatic drugs (DMARDs), or immunosuppressants such as azathioprine and cyclosporine is not advised.
Baricitinib blocks the action of Janus kinase (JAK). JAKs are enzymes in cells that help to transmit signals that influence the formation of the components of blood cells and their function as immune cells. The signals originate on the cell membrane surface due to interactions between cytokine and growth-factor receptors. Within this signaling system, JAKs normally chemically activate STATs (signal transducers and activators of transcription), which control the activity of the cells. Baricitinib prevents JAKs from activating the STATs. The actual importance of this blocking of the JAK enzyme’s action in relation to baricitinib’s medicinal action is not fully understood.
Baricitinib affects your immune system, and you may be more prone to getting infections. Your doctor may want to check you do not have any infections, such as tuberculosis, before starting your treatment.
Olumiant is available in tablet form in the following doses: 1 mg, 2 mg, and 4 mg.
You are advised to read the medication guide provided with this medicine for the drug information and patient information, and always speak with your healthcare provider for medical advice about any changes to your dose so they can monitor and evaluate your condition.
