Learn about side effects, antibodies, cost, and more. PROMETHEUS® Anser® IFX measures both serum infliximab levels and antibodies to infliximab – valuable information to help guide your treatment decisions for patients who lose response to infliximab. Infliximab should only be used during pregnancy if clearly needed.

If you are on infliximab, you should avoid contact with children who have been given the 'live' polio vaccine for 4-6 weeks after the vaccination: there is, however, an 'inactivated' polio vaccine available. If you require immunization with a live vaccine, infliximab should be stopped 6 months before and until 4 weeks after vaccination. The detection of anti-Infliximab antibodies also guides management decisions on concomitant immunosupression , dose escalation, drug switching and withdrawal.

Background Therapeutic drug monitoring (TDM) of infliximab (IFX) provides an objective measure that allows physicians to optimize the dose for patients on biologic therapies and potentially reduce loss of response (LOR). The currently accepted therapeutic range is 3 – 7 μg/mL. To get insight in the prevalence of high, or low/no serum infliximab trough levels in patients with low disease activity and if serum trough levels are stable and reliable longitudinally we conducted a prospective cohort study In a longitudinal, observational cohort of RA patients treated with infliximab for at least 6 months, treatment interval, DAS28, infliximab trough levels and anti
