Generic equivalents: There is some controversy about the differences between brand name prescription medications and their generic equivalents. For most medications there is no significant difference. For certain brand name drugs that have specialized timed-release characteristics, their may not be a specific generic equivalent. Switching from one manufacturer to another can sometimes require a dose adjustment.

Brand/Generic: I wish that i could provide you with a very informative answer, I am familiar with the regulations of the U.S. In the us, the brand is better in that there is consistent bioavailability due to the regulation that brand cannot vary more than 1% (0.5 above and 0.5 below) from one batch to another, but generics can vary by 20% (10 above and 10 below). Someone from europe should help clarify.

I have had patients start with the brand and switch to the generic and not notice any difference in the effect.
