Belgium had a small generic medicines market during the second half of the 1990s. Its development was boosted by the introduction of a reference-pricing system in 2001. Public expenditure on generic medicines rose from Euros 18 million in 1994 (market share by value of 0.8%) to Euros 213 million in 2004 (market share of 4.8%) .
The market share of generic medicines by volume nearly quadrupled from 2.2% in 1994 to 8.0% in 2004 .

In Belgium, control is exercised over the prices of all medicines. This control can take
the form of either price fixing or price notification, depending on the type of medicine .
Physicians in Belgium are not trained at medical school to write prescriptions by international non-proprietary name (INN). However, since 2006 physicians have been required to prescribe minimum percentages of low-cost prescriptions (so-called ‘quotas’) in order to benefit from the savings due to the lower costs of generics .
In 2008, only 3% of prescriptions in Belgium were written by INN .
Highlights of the generics market in Belgium
- The market share of generic medicines by volume (prescriptions) in 2008 was only 8.8%, representing around 5% in market value .
- Physicians are obliged to prescribe a certain amount of low-priced medicines .
- Substitution by the pharmacist is allowed if the prescription is written by INN and if the patient agrees with substitution .
