Software glitch changing doses on GP scripts for RHD drug

The issue could result in potential under-dosing in patients with acute rheumatic fever and rheumatic heart disease

A glitch in Best Practice software means the wrong dosages have been printed when doctors issue repeat scripts for a rheumatic heart disease (RHD) treatment.

SA Health has urged all GPs who manage patients with acute rheumatic fever or RHD to be aware of the issue when prescribing Bicillin LA injections, warning it could result in significant under-dosing.

The issue emerged after Pfizer changed the unit measurements for the long-acting penicillin from 900mg/2.3mL to 1,200,000 units/2.3mL in early 2019.
