A survey has found about a quarter (24 per cent) of New Zealanders who used an over-the-counter painkiller in the past three months took one which contained codeine and half of those people (47 per cent) consumed the addictive drug unwittingly.
Australasian owned AFT Pharmaceuticals commissioned The Nielsen Company to conduct a survey to shed light on painkiller use which had previously only been anecdotal. It found 88 per cent of New Zealanders had taken an oral painkiller in the past three months.
AFT founder Dr Hartley Atkinson has devoted much of his career to developing a non-codeine painkiller because of codeine’s addictive potential, and side effects such as nausea, vomiting and constipation when taken for more than a few days.
He eventually designed non-codeine Maxigesic®, which combines paracetamol and ibuprofen to provide additional pain relief without using codeine.
Dr Atkinson says the survey highlights almost half the population is ignorant to the potential dangers of codeine, and underlines the need for addiction warning labels which are being introduced in October this year.
“Many people take popular over-the-counter painkillers for a few days in a row without considering the possible consequences.
“So it is of real concern that 44 per cent of the population are unsure whether codeine can be addictive, wrongly say it is not addictive, or don’t even know what codeine is,” said Dr Atkinson.
“The survey provides excellent consumer-based statistics which give context to research published by The New Zealand Medical Journal on addiction to over-the-counter painkillers, and reports from the Alcohol and Drug Foundation that addiction to codeine is on the increase.”
“The survey found young adults aged 18 to 24 are significantly more likely to say they don’t know what codeine is. That should concern us all.”
More stringent restrictions on the sale of painkillers containing codeine come into force in October, following growing concern among health experts about codeine addition and mis-use of painkillers. Depending on the level of codeine, they will become either behind-the-counter or prescription-only drugs.
The new requirements include addiction warning labels and reduced packet sizes, and the recording of purchaser details.
“There are codeine-free alternatives available now, and the changes cannot come soon enough. Australia brought in similar rules for codeine-based products in May, and the UK put a regime of warnings and restrictions in force last year,” said Dr Atkinson.
