Empiric Antibiotic Therapy for Bacterial Meningitis
Empiric coverage for community-acquired bacterial meningitis typically pairs vancomycin with a third-generation cephalosporin; ampicillin is added for Listeria coverage in older or immunocompromised patients.
This tool is for educational and decision-support use only. It does not replace independent clinical judgement. Always verify against the current guideline, FDA label, or specialty reference cited below before acting. Do not enter patient identifiers (name, MRN, dates of service).

Frequently asked questions
Does the tool know my hospital's antibiogram?
No. Local antibiogram and resistance patterns must be applied by the clinician or pharmacist before finalising therapy. The tool always emits a 'must_check_before_acting' field reminding the user.
Will it adjust for renal function?
Not directly. Use the Renal / Hepatic Dose Adjustment Lookup tool, the FDA label, or institutional pharmacy after the empiric regimen is chosen.
Can I trust the duration recommendations?
Durations follow the cited guideline at time of training. Recent guideline updates (e.g. shortened CAP courses) should be verified against the current IDSA / ATS publication.
Does it cover paediatrics?
Paediatric regimens follow paediatric IDSA / AAP guidance; identify the patient population in the input. Always verify paediatric weights and renal status.
What about culture-directed therapy?
Once cultures and susceptibilities return, narrow therapy per stewardship principles; the empiric regimens are starting points, not endpoints.
