Practical Prescribing Tips
- Follow local guideline tables but adapt dosing/frequency for severe infection (e.g., more frequent beta-lactam dosing).
- Prefer once-daily aminoglycoside dosing per recent guidelines for tolerability if used; avoid prolonged synergistic regimens when harmful.
Treating Streptococcal Endocarditis
- Treat penicillin-susceptible streptococcal endocarditis with high-dose benzylpenicillin or ceftriaxone for 4–6 weeks.
- Add gentamicin for the first two weeks in selected native-valve cases to shorten therapy to 2–4 weeks per guideline specifics.
Managing Staphylococcal Cases
- For staphylococcal native-valve endocarditis use anti-staphylococcal beta-lactams (fluclox/oxacillin/nafcillin) when susceptible.
- For MRSA or penicillin allergy use vancomycin or high-dose daptomycin (6–10 mg/kg) and add rifampicin/gentamicin for prosthetic valves.
