  2. Further dilution is not necessary.
  3. Filter prior to administration through a Pall 0.22 micron filter.
  4. Administer by slow IV injection over 3-5 minutes.
  5. Is compatible with D5W, D10W and NS. Incompatible with IVN, phenobarbitone and ranitidine.
  6. Do NOT mix with other drugs, IV solutions, blood or blood products.

Continuous IV Infusion

Administered by a nurse with neonatal IV drug certification.

  2. Administer via a syringe pump.
  3. Change fluid and tubing every 24 hours.

Nursing Considerations

  2. Monitor and record patient response to medication.
  3. Observe site closely for extravasation.
