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).
(a) More expensive Costco bottle price as a multiple of less expensive Costco bottle price and additional yearly cost of medication in USA over Canada
(b) More expensive Costco bottle price as a multiple of less expensive Costco bottle price and additional yearly cost of medication in USA over Canada
