Depends where you live. In the US 100 I.E of Botox costs around $300.00 In Belgium it's around $ 200.00 Same company (Allergan). We should do something about these price differences in different countries!!!! There is also a large difference in the price of the deep brain stimulators in different countries. We shoiuld try to compare these prices and confront the different companies. If anyone is interested in the price of DBS in Belgium, please let me know. Greetings, Chris
