Monitoring:

Pre and post dose levels are applicable only to patients with endocarditis [dosing usually tds (8 hourly) but occasionally bd (12 hourly) or once daily].

For once daily dosing (non-endocarditis), both levels are 'post' (at 30 minutes and 6 hours after the dose).

Random gentamicin levels may be performed if requested, as advised by pharmacy.

Angliss, Box Hill and Maroondah pharmacy staff will calculate appropriate dosing using these levels and recommend dose adjustment if required. Contact pharmacy for this service.
