New data has revealed that a number of Queenslanders have put off buying prescribed medicines and seeking medical care due to high costs.

According to the data released by the Productivity Commission, 8 per cent of people in Queensland put off access to prescribed medication, and around 4.5 per cent put off trips to the GP in the last year.

President of the Royal Doctors Association of Queensland, Dr Konrad Kangru, says this is a particular problem in remote areas, where the cost of medical care is generally higher than in the cities.
