Drug Interactions
Etanercept does not undergo CYP metabolism, so pharmacokinetic interactions are limited. The major concerns are immunologic and additive immunosuppression.
- Live vaccines (e.g., MMR, varicella, yellow fever, intranasal influenza): Should not be administered during etanercept therapy due to risk of disseminated vaccine infection. Bring vaccinations up to date before starting therapy.
- Anakinra and abatacept: Combining etanercept with these immunomodulators substantially increases serious infection risk without proven added efficacy. Concurrent use is not recommended.
- Other biologic DMARDs (e.g., adalimumab, infliximab, rituximab): Sequential use is common, but simultaneous combination raises infection and malignancy risk and should be avoided.
- Cyclophosphamide: A higher rate of solid malignancies has been reported when TNF inhibitors are combined with cyclophosphamide. Avoid concurrent use.
- Sulfasalazine: Concomitant use has been reported to lower neutrophil counts compared to either drug alone. Monitor CBC if used together.
- CYP450 substrates with narrow therapeutic indices (e.g., warfarin, theophylline, cyclosporine): TNF inhibition during chronic inflammation can normalize CYP450 expression that was previously suppressed by cytokines, altering drug levels. Monitor closely after etanercept initiation or discontinuation.
