Comparison of United States and Canadian Glaucoma Medication Costs and Price Change from 2006 to 2013

Figure 1

The -axis first lists brand name medications (a) and then generic medications (b). The -axis is the more expensive Costco bottle price as a multiple of less expensive Costco bottle price for each medication. A value of 0 (dashed line) indicates that the cost of the medication in both countries is the same. A positive value indicates that the medication in the USA is more expensive than that in Canada, and a negative value indicates that the medication in Canada is more expensive than that in the USA. For instance, Lumigan is 3.5x more expensive in the USA than in Canada. The $ value after each bar represents the additional yearly cost of the medication in the USA over Canada (negative means that medication was more expensive in Canada).
