Background: Transjugular intrahepatic portosystemic shunt (TIPS) alters portal blood flow and may impact drug metabolism and bioavailability. However, little evidence has been published to provide guidance on medication alterations after TIPS procedures.
Case Report: We report a patient who developed phenytoin toxicity requiring a prolonged readmission after a TIPS procedure. It is likely that the TIPS procedure altered phenytoin metabolism and led to toxicity in this patient. Phenytoin is an antiepileptic drug that is primarily eliminated by hepatic metabolism. It is possible that phenytoin toxicity may occur after TIPS, and that decreased dose requirements may be a durable effect of the procedure. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: TIPS is now the most common portal hypertension decompressive procedure performed by interventional radiologists and has become the primary portosystemic shunt (surgical or percutaneous) performed in the United States. Patients with a history of TIPS procedures commonly present to tertiary- and quaternary-care emergency departments with complex clinical presentations. Greater familiarity with the potential effects of TIPS on drug metabolism may help emergency physicians prevent adverse drug effects and optimize clinical outcomes.

Sulfonamides are associated with severe cutaneous adverse reactions (SCARs). Coronavirus disease 2019 (COVID-19) triggers an immune response, which may increase the likelihood of developing a hypersensitivity reaction. We sought to explore the impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection on the probability of developing SCARs and/or erythema multiforme (EM) reactions to sulfonamides.

Phenytoin is a well-known anticonvulsant medication that is useful in the management of most seizure disorders. Given the narrow therapeutic index of 10-20 mg/mL, acute phenytoin overdose can occur with either oral or intravenous administration. There is no distinct antidote to phenytoin, and therefore supportive care is the treatment of choice.
