empirical antibiotics

Last reviewed 01/2018

Prescription of antibiotics empirically is a balance between doing the job scientifically and doing it quickly. The hazards of prescribing empirically include:

  • resistant organism
  • superinfection
  • adverse effects
  • obscuring the diagnosis

Therefore, make a diagnosis, preferably a bacteriological one. Take specimens, if appropriate, and make a clinical diagnosis. The relevant section of the BNF and a local microbiology service will give the best bet of organism and the relevant antimicrobial therapy.

Therapy should be modified upon receipt of results of culture if appropriate.
