Other Comments

Administration advice:

• For IV or IM use
• IV: Infuse over 30 minutes; do not use with a needleless IV system.
• IV: Complete the infusion within 6 hours of reconstitution.
• IM: May use as an alternative to IV administration for infections where IM therapy is appropriate; administer by deep IM injection into a large muscle mass (e.g., gluteal muscles, lateral part of the thigh); use caution to avoid inadvertent injection into a blood vessel.
• IM: Use the IM solution within 1 hour after reconstitution.
• May administer by IV infusion for up to 14 days or by IM injection for up to 7 days
• Do not administer the reconstituted solution IV.
• Do not co-infuse with other drugs.

Storage requirements:

• Before reconstitution: Do not store above 25C (77F).
• Reconstituted and infusion solutions: Reconstituted solution (immediately diluted) may be stored at room temperature (25C) and used within 6 hours or stored for 24 hours refrigerated and used within 4 hours after removal from refrigerator; do not freeze solutions.

Reconstitution/preparation techniques:

• This drug must be reconstituted and then diluted before IV administration.
• This drug must be reconstituted with lidocaine (without epinephrine) before IM administration.
• Diluents containing dextrose (alfa-D-Glucose) should not be used.
• The manufacturer product information should be consulted.

• Do not mix with other drugs.

General:

• This drug is for the specified moderate to severe infections due to susceptible isolates of the designated microorganisms.
• To reduce the development of drug-resistant organisms and maintain effective therapy, antibiotics should be used only to treat or prevent infections proven or strongly suspected to be caused by susceptible bacteria.
• Culture and susceptibility information should be considered when selecting/modifying antibacterial therapy or, if no data are available, local epidemiology and susceptibility patterns may be considered when selecting empiric therapy.

Monitoring:

• General: Organ system functions, including renal, hepatic, and hematopoietic (periodically during prolonged therapy)
• Hematologic: Hematopoietic function (periodically during prolonged therapy)
• Hepatic: Hepatic function (periodically during prolonged therapy)
• Renal: Renal function (periodically during prolonged therapy)

Patient advice:

• Avoid missing doses and complete the entire course of therapy.
• Contact physician as soon as possible if watery and bloody stools (with or without stomach cramps and fever) develop.
