Abstract

International literature suggests that co-payment increases are associated with decreased medicine use, although the effects depend on context. We examined the impact of a co-payment increase on the consumption of type 2 antidiabetics in Finland, a country with a comprehensive health and social security system including ceiling mechanisms aiming to protect patients from high co-payment expenditures.
