What a waste!


Rum bin 1

What are the 20 medicines that are most commonly dumped in your pharmacy’s RUM bin?

An article reviewing the findings of the two most recent audits of Return Unwanted Medicines Project bins has revealed a snapshot of exactly which drugs people are not actually using.

In 2016 the Project collected over 704 tonnes of unwanted medicines. An audit undertaken that year found that the most commonly returned medicines were unexpired opened packets of medicines for the treatment of acute conditions. They included paracetamol, salbutamol and glyceryl trinitrate.

The review article, published in Australian Prescriber, found that six of the most commonly returned PBS medicines in 2016 are used for chronic conditions, and three – atorvastatin, simvastatin and metformin – were in the top 20 most prescribed PBS medicines.

The 2016 audit assessed the types and amounts of medicines returned via the RUM Project at the three national incineration sites (Brisbane, Perth and Melbourne). On average, 13,000 RUM bins per month are collected for incineration. The audit aimed to examine the contents of a nationally representative sample of 423 bins.

Among the findings were:

  • 60% of the returned items were PBS medicines: of these – 55% were prescription only (Schedule 4), 1% were controlled drugs (Schedule 8), 4% were pharmacist-only medicines (Schedule 3 – these were assumed to be PBS medicines).
  • 10% of items were over-the-counter medicines (Schedule 2).
  • 14% were dose administration aids.
  • 11% were unscheduled medicines.
  • 4% were complementary medicines.
  • 1% were international, and unknown schedule medicines.

* The 2013 audit was of 377 RUM bins. Although the processes were similar in the 2016 audit, the 2013 audit considered any quantity of a returned medicine as a full pack (i.e. the full dispensed amount). In the 2016 audit, the exact quantity of each medicine returned was counted.
