2.1 Important Dosage and Administration Instructions

• Use the lowest effective dosage for the shortest duration consistent with individual patient treatment goals [see Warnings and Precautions (5.4)].
• Do not exceed the maximum total daily dose of COMBOGESIC IV (4,000 mg acetaminophen and 1,200 mg ibuprofen) in 24 hours.
• Do not exceed a total daily dose of 4,000 mg (4 g) acetaminophen from all sources.
• Do not co-administer COMBOGESIC IV with other acetaminophen or ibuprofen containing products [see Warnings and Precautions (5.2)].
• Visually inspect for particulate matter and discoloration prior to administration. If visibly opaque particles, discoloration, or other foreign particulates are observed, do not use.
• Use COMBOGESIC IV in one patient on one occasion only. It contains no antimicrobial preservative. Discard any unused solution.
• Do not mix with diluents or with other medicines.

2.2 Recommended Dosage

For adult patients weighing greater than or equal to 50 kg (actual body weight): The recommended dosage of COMBOGESIC IV is one vial (100 mL; acetaminophen 1,000 mg/ibuprofen 300 mg) administered as a 15-minute infusion every 6 hours, as necessary.

For adult patients weighing less than 50 kg (actual body weight): The recommended dosage is 15 mg/kg acetaminophen and 4.5 mg/kg ibuprofen, administered as a 15-minute infusion every 6 hours, as necessary. This equates to a maximum single dose of 750 mg acetaminophen and 225 mg ibuprofen (discard remaining medicine in vial), and a total daily dose of 3,000 mg (3 g) acetaminophen and 900 mg ibuprofen.

2.3 Instructions for Intravenous Administration

• Administer as a 15-minute intravenous infusion.
• Do not mix other medications with the COMBOGESIC IV vial or infusion device.
• As for all solutions for infusion presented in glass vials, monitor closely, particularly at the end of infusion, regardless of administration route, in order to avoid air embolism. This applies particularly for central route infusion.
• To decrease the likelihood of bung fragmentation or the bung being forced into the vial, use a syringe or giving set with a diameter equal to or below 0.8 mm for solution sampling and ensure that the bung is pierced at the location specifically designed for needle introduction (where the thickness of the bung is the lowest).
• The entire 100 mL container of COMBOGESIC IV is not intended for use in patients weighing less than 50 kg. For doses less than 1,000 mg acetaminophen and 300 mg ibuprofen, the appropriate dose must be withdrawn from the container and placed into a separate container prior to administration. Using aseptic technique, withdraw the appropriate dose (weight-based) from an intact sealed COMBOGESIC IV container and place the measured dose in a separate empty, sterile container (e.g., glass bottle, plastic intravenous container, or syringe) for intravenous infusion to avoid the inadvertent delivery and administration of the total volume of the commercially available container. COMBOGESIC IV is supplied in a single-dose container and the unused portion must be discarded.
