- For oral administration, a common starting dose is 400 mg every 4 hours, with a maximum daily dose of 2.4 g/day [ 1 ].
- The intravenous dose can range from 650 mg every 4 hours to 1000 mg every 6 hours, with a maximum daily dose of 4 g/day [ 1 ].
- Treatment duration for acute musculoskeletal conditions is usually limited to 2 to 3 weeks, while for chronic conditions, the dose and frequency may be adjusted based on individual patient response.
Administration Options
- Oral: 400 mg every 4 hours, with a maximum daily dose of 2.4 g/day [ 1 ].
- Intravenous: 650 mg every 4 hours to 1000 mg every 6 hours, with a maximum daily dose of 4 g/day [ 1 ].

From the FDA Drug Label
DOSAGE AND ADMINISTRATION For Intravenous and Intramuscular Use Only. Total adult dosage should not exceed 30 mL (3 vials) a day for more than 3 consecutive days except in the treatment of tetanus. For the relief of symptoms of moderate degree, one dose of 1 gram (one 10 mL vial) may be adequate. For the severest cases or in postoperative conditions in which oral administration is not feasible, additional doses of 1 gram may be repeated every 8 hours up to a maximum of 3 g/day for no more than 3 consecutive days.

- 1 gram (one 10 mL vial) for moderate symptoms, which may be adequate as a single dose
- 1 gram repeated every 8 hours, up to a maximum of 3 g/day for no more than 3 consecutive days for severe cases or postoperative conditions 2
