Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults aged 18 and older with penicillin-susceptible Staphylococcus aureus bacteraemia.
✕Probably not a fit
Patients with a penicillin allergy or those who are in terminal palliation may not benefit from this study.

What this trial studies
This clinical trial aims to determine whether benzylpenicillin is a more effective treatment than cloxacillin for patients with penicillin-susceptible Staphylococcus aureus bacteraemia. Adult patients over 18 years old diagnosed with this condition will be randomly assigned to receive either benzylpenicillin or cloxacillin after their blood cultures confirm the presence of the bacteria. The study will monitor treatment outcomes, including adverse events and effectiveness, over a specified duration based on the type of infection. The trial is designed to provide insights into optimizing antibiotic therapy for this serious infection.
Why it matters
Potential benefit: If successful, this study could lead to improved treatment options for patients suffering from Staphylococcus aureus bloodstream infections.
How similar studies have gone: While the comparison of these two antibiotics has not been extensively studied, previous research has indicated the importance of optimizing antibiotic therapy for Staphylococcus aureus infections.

Inclusion Criteria: Aged ≥18 with penicillin susceptible S. aureus bacteraemia (PSSA), and able to provide written informed consent. Exclusion Criteria: * allergy to penicillin, * inability to give informed consent, * concomitant growth of other clinically significant bacteria in blood cultures * neutropenia -≥ 96h with prior antibiotics * When the per oral follow up medication can not be flukloxacillin or penicillinV/Amoxicillin (ie prosthetic joint infection) * Patients in terminal palliation, where death is expected within 7 days. * Where the treating physician believes cloxacillin is not a first-line treatment.
