Administration advice:

  • For lumbar epidural administration only; not intended for intrathecal, intravenous, or intramuscular administration
  • Do not use an in-line filter during administration
  • Proper needle or catheter placement into epidural space must be verified prior to injection; administration at the thoracic level or higher is not recommended because it has not been studied.
  • Once administered, no other medication should be administered into the epidural space for at least 48 hours

Storage requirements:
  • Protect from freezing; each vial has a freeze indicator that should be checked prior to administration. If the bulb of the freeze indicator changes from clear to pink or purple, the vial may have frozen and should not be used.

  • Unopened intact vials may be held at room temperature for up to 30 days, after 30 days they should be discarded; these vials should not be returned to the refrigerator.

Reconstitution/preparation techniques:
  • May be administered undiluted or may be diluted to a total volume of up to 5 mL (dilute with preservative-free 0.9% normal saline)
