As of yesterday, codeine-containing medicines that were once freely available over-the-counter now require a prescription, thanks to new regulations introduced by the Therapeutic Goods Administration.
A full list of affected products is available on the TGA website and includes the likes of Panadeine, Mersyndol and Nurofen Plus.
Note that the ban does not encompass codeine derivatives such as dextromethorphan and pholcodine.
Of course, if you need help for your particular situation, your best bet is to consult your GP.
From February 1, 2018 all products that contain codeine will only be available for sale in pharmacies with a prescription. This means you won’t be able to buy brands like Nurofen Plus, Panadeine or Panadeine Extra over the counter at your local pharmacy without a prescription from your doctor.
