This disparity influences prescription trends, with many rural patients relying heavily on local pharmacists for guidance and medication. Price sensitivity is another critical aspect. The cost of varenicline can deter potential users, especially if their budget is already tight. Many Australians depend on the Pharmaceutical Benefits Scheme (PBS) to manage medication costs. Trust in local pharmacists becomes essential, as patients weigh their options. This community reliance fosters a sense of connection, ultimately shaping how Australians perceive and utilise varenicline as a smoking cessation tool.

This convenience allows users to access varenicline from the comfort of their homes, offering an alternative for those who may not wish to visit a physical pharmacy. The pricing pattern for varenicline reveals notable disparities between PBS-subsidised prices and private prices. PBS usually offers lower costs, helping many users manage their finances.
