Pharmaceutical Benefits Scheme
Certain medications listed on the PBS are available only for specific therapeutic indications or to patients meeting specific criteria where the PBAC has deemed that the cost-benefit analysis is favourable only in those indications/patients. These are noted as "restricted benefits" on the Schedule. Medicare Australia places the onus of policing restricted benefits on the prescribers themselves and the pharmacists dispensing (unless the listing is also 'Authority Required'). For example, the COX-2 inhibitor celecoxib is listed on the PBS as a restricted benefit for the symptomatic treatment of osteoarthritis and rheumatoid arthritis. Prescribers using celecoxib for other indications are expected to indicate "non-PBS" on the prescription, and/or the pharmacist dispensing the celecoxib should charge the patient the full cost.
Tijuana
Tijuana has many pharmacies that target visitors from the United States, which sell some medicines without prescriptions and/or at much lower costs than in the U.S. Many medications still require a Mexican prescription, which can be obtained from adjacent doctors' offices. People filling up prescriptions for drugs classified in the US as Schedule II or Schedule III have found it more difficult to locate such medications, and the purchase of pseudoephedrine also has become restricted by Tijuana pharmacies, just as in the U.S. To fill a prescription in Tijuana for any drug covered by the US Controlled Substances Act and legally bring it into the United States requires a prescription from the United States for re-import. Americans can import up to a 90-day supply of non-controlled medications for personal use to the USA from Mexico and other countries.
