Contraindication

VARUBI is contraindicated in patients:

  • With known hypersensitivity to any component of the product (including soybean oil).
  • Taking CYP2D6 substrates with a narrow therapeutic index, such as thioridazine and pimozide. VARUBI can significantly increase the plasma concentrations of thioridazine and pimozide, which may result in QT prolongation and Torsades de Pointes.

Warnings and Precautions

  • Anaphylaxis, anaphylactic shock and other serious hypersensitivity reactions have been reported with VARUBI IV, most often immediately following initiation of infusion. If symptoms occur, stop the infusion, initiate appropriate medical management, and permanently discontinue VARUBI IV.
  • VARUBI is a moderate inhibitor of CYP2D6 and significantly increases the plasma concentrations of CYP2D6 substrates for at least 28 days, with inhibitory effects expected to persist for an unknown duration.
  • Monitor for adverse reactions when VARUBI is coadministered with CYP2D6 substrates without a narrow therapeutic index (avoid coadministration with CYP2D6 substrates with a narrow therapeutic index, thioridazine and pimozide; see Contraindication). Consider interactions with CYP2D6 substrates before starting treatment with VARUBI.
