These drugs are commonly used for the treatment of inflammatory arthritis (eg, rheumatoid arthritis, psoriatic arthritis, spondyloarthritis). Not all drugs are approved for all uses by all regulatory agencies.
These are general guidelines. Patients should be assessed on an individual basis to determine if they require additions or other modifications to the monitoring noted in this table.CBC: complete blood cell count (hematocrit, hemoglobin, white blood cell count, including differential white blood cell count and platelet counts); COPD: chronic obstructive pulmonary disease; IL-6: interleukin 6; JAK: Janus kinase; LFTs: liver function tests; PDE4: phosphodiesterase-4; PML: progressive multifocal leukoencephalopathy; PMNs: polymorphonuclear leukocytes; TB: tuberculosis; TNF: tumor necrosis factor.
* Confirm that immunizations are up to date in all patients.
¶ Screening for latent TB prior to all biologic DMARDs and prior to use of a JAK inhibitor, and repeat TB testing in patients at increased risk of or with known exposure to TB and patients treated for latent TB with potential ongoing exposure.
Δ Patients receiving a biologic DMARD or JAK inhibitor should also continue appropriate monitoring for concurrent conventional DMARD therapies.

§ In patients receiving methotrexate and leflunomide in combination: CBC, creatinine, albumin, and transaminases every 2 to 4 weeks for the first 3 months or following dose increase, every 4 weeks for the next 3 months, then every 3 months.Do you want to add Medilib to your home screen?
