May take with or without food

Increased risk of serious bacterial, fungal, viral and opportunistic infections leading to hospitalization or death, including tuberculosis (TB). Interrupt treatment with Baricitinib if serious infection occurs until the infection is controlled. Baricitinib should not be given to patients with active tuberculosis. Test for latent TB before and during therapy, except for COVID-19; treat latent TB prior to use. Higher rate of all-cause mortality, including sudden cardiovascular death with another Janus kinase inhibitor (JAK) vs. TNF blockers in rheumatoid arthritis (RA) patients. Malignancies have occurred in patients treated with Baricitinib. Higher rate of lymphomas and lung cancers with another JAK inhibitor vs. TNF blockers in RA patients. Higher rate of MACE (defined as cardiovascular death, myocardial infarction, and stroke) with another JAK inhibitor vs. TNF blockers in RA patients. Thrombosis has occurred in patients treated with Baricitinib. Increased incidence of pulmonary embolism, venous and arterial thrombosis with another JAK inhibitor vs. TNF blockers. Gastrointestinal Perforations: Monitor patients who may be at increased risk and evaluate promptly new onset of abdominal symptoms. Vaccinations: Avoid use with live vaccines. Hypersensitivity: Serious reactions have been reported. Monitoring Parameters Monitor laboratory values (lymphocytes, neutrophils, hemoglobin, liver enzymes, and lipids) at baseline and periodically during treatment Monitor all patients for active TB during treatment, even patients with initial negative, latent TB test. Monitor patients with hepatitis B surface antibody and hepatitis B core antibody, without hepatitis B surface antigen, for expression of hepatitis B virus (HBV) DNA—if HBV DNA detected, consult liver specialist for advice. Monitor lipid profile 12 weeks after treatment initiation—hyperlipidaemia should be managed according to international clinical guidelines; Monitor hepatic transaminases routinely—interrupt treatment if drug-induced liver injury suspected. Monitor for haematological abnormalities; interrupt treatment if absolute neutrophil count less than 16109 cells/litre, absolute lymphocyte count less than 0.56109 cells/litre, or haemoglobin less than 8 g/dL—treatment may be restarted when levels return above these values.

Pregnancy Based on findings from animal reproduction studies, therapy may cause fetal harm during pregnancy; available data from clinical trials and postmarketing reports of exposure in pregnancy are insufficient to inform a drug-associated risk for major birth defects, miscarriage, or other adverse maternal or fetal outcomes There are no human data on chronic baricitinib exposure throughout pregnancy; there are risks to mother and the fetus associated with rheumatoid arthritis in pregnancy; consider risks and benefits with chronic use during pregnancy Published data suggest that increased disease activity is associated with risk of developing adverse pregnancy outcomes in women with rheumatoid arthritis; adverse pregnancy outcomes include preterm delivery (before 37 weeks of gestation), low birth weight (less than 2500 g) infants, and small for gestational age at birth Based on animal studies, therapy may cause fetal harm when administered during pregnancy; consider pregnancy planning and prevention for females of reproductive potential Animal studies In animal embryo-fetal development studies, oral baricitinib administration to pregnant rats and rabbits at exposures equal to and greater than ~20 and 84 times the maximum recommended human dose (MRHD), respectively, resulted in reduced fetal body weights, increased embryo lethality (rabbits only), and dose-related increases in skeletal malformations Lactation Unknown if distributed in human breast milk Baricitinib is present in the milk of lactating rats Owing to species-specific differences in lactation physiology, the clinical relevance of these data are not clear Because of the potential for serious adverse reactions in nursing infants, advise women with rheumatoid arthritis not to breastfeed while taking baricitinib

Avoid use of live vaccines; update immunizations in agreement with current immunization guidelines before initiating Coadministration with strong OAT3 inhibitors may increase baricitinib systemic exposure Contraindicated (1) upadacitinib

Janus kinases (JAKs) pathways inhibitor; JAK consists of a group of intracellular tyrosine kinases that transmit signals from cytokine or growth factor-receptor interactions on the cellular membrane to influence cellular processes of hematopoieses and immune cell function Within the signaling pathway, JAKs phosphorylate and activate signal transducers and activators of transcription (STATs), which modulate intracellular activity including gene expression; baricitinib modulates the signaling pathway at the point of JAKs, preventing the phosphorylation and activation of STATs
