How PBS prices work in Australia
Prices on this page are the approved ex-manufacturer price on the Pharmaceutical Benefits Scheme (PBS): what the Australian Government has agreed to pay the supplier for the pack. Pharmacy mark-up and dispensing fees are added on top. Patients with a PBS prescription do not pay this price; they pay a government-capped co-payment (lower for concession card holders), and the PBS covers the rest.
