70% of medications are ineffective or cause side effects This is because more than 99% of us have a change in our DNA which affects how we metabolise medications. This is called pharmacogenomics (PGx). The current approach to prescribing medicines often involves a trial-and-error approach. This places a significant burden on the healthcare system and increased healthcare costs. If PGx testing was implemented in Australia the predicted healthcare savings just from reducing adverse side effects is predicted to be more than $1billion. PGx testing provides a personalised approach to medication management. Analysing a patient’s genetic makeup can help healthcare providers identify which medications are most likely to be effective with the lowest associated adverse drug reactions.
