Use within several hours after preparation. Reconstitute with SWFI.

Further dilute with a compatible solution; sodium chloride 0.9% (NS) is the diluent of choice for IV piggyback use; final concentration should not exceed 45 mg/mL Unasyn (30 mg/mL of ampicillin and 15 mg/mL of sulbactam).

This means 750mg should be diluted to about 17ml at least.

Administered by slow IV injection over 10 to 15 minutes or by intermittent IV infusion over 15 to 30 minutes.
