In suspected meningitis, starting effective therapy quickly is crucial. If lumbar puncture cannot be done safely, you should not delay treatment for diagnostic procedures. The best action is to obtain blood cultures and start empiric IV antibiotics immediately. Drawing blood cultures first helps identify the pathogen, but antibiotics should not wait for CSF confirmation because delays increase mortality and worsen outcomes. Use broad-spectrum coverage appropriate for the patient’s age and risk (for example, vancomycin plus a third-generation cephalosporin, with ampicillin added if Listeria is a concern). Dexamethasone can be given as an adjunct with the first antibiotic dose in adults with suspected bacterial meningitis, but it is not sufficient as sole initial therapy. LP without imaging is not appropriate when there are contraindications, since the safety of the procedure cannot be guaranteed.
