Interactions between your drugs
etanercept rilonacept
Applies to: etanercept, rilonacept
GENERALLY AVOID: The use of an interleukin-1 (IL-1) blocker in combination with a tumor necrosis factor (TNF) blocker may increase the risk of neutropenia and serious infections, possibly due to additive immunosuppressive effects. In a clinical study, neutropenia occurred in 3% and serious infections in 7% of patients receiving the IL-1 blocker anakinra in combination with a TNF blocker (n=58). No added benefit has been observed with the combination relative to either agent alone.
MANAGEMENT: Concomitant use of an IL-1 blocker and a TNF blocker is not recommended.
