  • For IM injection, reconstitute by adding 5.7 or 11.4 mL of SWI to a vial containing 1 or 2 g of oxacillin, respectively, to provide solutions containing 167 mg of oxacillin per mL (250 mg/1.5 mL)
  • Shake vials well

IV Injection

  • For direct injection, prepare a solution containing approximately 100 mg/mL by adding 10 or 20 mL SWI, ½NS or NS to vials containing 1 or 2 g of oxacillin, respectively

Intermittent or Continuous IV Infusion

  • For intermittent IV infusion, reconstitute vials containing 1 or 2 g as for direct IV injection & further dilute with a compatible IV solution to a concentration of 0.5-40 mg/mL
