If ceftriaxone iv is utilized in place of cefotetan/cefoxitin iv as inpatient pid regimen, what would be appropriate dose of ceftriaxone iv?

Depends: It depends on what is being treated, what the sensitivity of the organism is and why changes are being made. Medications have different dosages that are appropriate for that medication that do not correlate with other medications. For instance we may use 1 million units of penicillin for an infection or 250 mg of Zithromax for the same infection. It has to do with the effective dose.
