Sterile cefoperazone sodium can be administered by IM or IV injection (following dilution). However, the intent of this pharmacy bulk package is for the preparation of solutions for IV infusion only.

The usual adult daily dose of CEFOBID is 2 to 4 grams per day administered in equally divided doses every 12 hours.

In severe infections or infections caused by less sensitive organisms, the total daily dose and/or frequency may be increased. Patients have been successfully treated with a total daily dosage of 6–12 grams divided into 2, 3, or 4 administrations ranging from 1.5 to 4 grams per dose.

When treating infections caused by Streptococcus pyogenes, therapy should be continued for at least 10 days.

If C. trachomatis is a suspected pathogen, appropriate anti-chlamydial coverage should be added, because cefoperazone has no activity against this organism.

Solutions of CEFOBID and aminoglycoside should not be directly mixed, since there is a physical incompatibility between them. If combination therapy with CEFOBID and an aminoglycoside is contemplated (see INDICATIONS) this can be accomplished by sequential intermittent intravenous infusion provided that separate secondary intravenous tubing is used, and that the primary intravenous tubing is adequately irrigated with an approved diluent between doses. It is also suggested that CEFOBID be administered prior to the aminoglycoside. In vitro testing of the effectiveness of drug combination(s) is recommended.

In a pharmacokinetic study, a total daily dose of 16 grams was administered to severely immunocompromised patients by constant infusion without complications. Steady-state serum concentrations were approximately 150 mcg/mL in these patients.
