The preferred calculator is on the Hospital Portals page [intranet only] as this calculator allows you to print a copy with reminders to document the patient's name and CHI and gives information on monitoring.
Otherwise use the Antimicrobial Companion app calculator. Both calculators use the same dosing calculation but the app requests you to round up a patient's body weight so there may occasionally be small differences in the calculated dose.
It is good practice to print a copy of the result for either calculator if printing is possible. The printed gentamicin dose calculation should be filed with the patients' prescription and administration record.
Please prescribe gentamicin on the (red) gentamicin prescription, administration and monitoring chart - available on wards or via your ward pharmacist.
For synergistic use in patients with endocarditis refer to Synergistic Gentamicin for Endocarditis in Adults Guideline [intranet only]
