Antimicrobial resistance is increasing and is a serious and worrying problem for patients, staff and healthcare organisations as a whole. Infections caused by resistant bacteria are associated with higher rates of death, illness and prolonged hospital stay. Bacteria often become resistant to antibiotics as a direct consequence of antibiotic use.  The use of these antibiotics is often unnecessary or inappropriate.  

The protected antimicrobial list has been implemented to preserve those antimicrobials that are still active against resistant organisms:

  • Antimicrobials from the table below should only be prescribed for an approved indication as listed
  • For any other indication seek advice from the duty Microbiologist or Infectious Disease Consultant before prescribing. In this case an authorisation code will be given which must be documented in the medical notes and on the prescription chart.
