This study explored the use of generic medicines among elders in Belgium. The generic market share by volume for elders in 2010 was 23.1%, while this was 23.7% for the total Belgian population in 2009. Pharmaceutical expenditure in Belgium was €649.74 per capita for elders in 2010. Calculations of possible savings through an increased use of generic medicines showed that these savings were rather limited (4.48% when the generic market share by volume increased to 95%). The full potential of generic medicines in the elder population has not yet been realized in Belgium, due to the limited use of generic medicines and their relatively high prices. The Belgian government should implement additional incentives for physicians, pharmacists, and patients to increase the use of generics and combine these with policies to lower prices of generic medicines and policies to decrease the volume of medicines used by elders and rationalize the prescribing of medicines for elders.
