In Australia brand substitution of pre-approved generic and brand medications is allowed in all cases except where a dr explicitly indicates otherwise. Whilst the active ingredients in all generic and brand name medications are the same the inactive ingredients may differ and change the way in which the medication is metabolised. This can adversely effect patients on AEDs (ant-epileptic drugs) potentially lowering medication efficacy and increasing unwanted side effects.Not all brands are created equally and we want the government to acknowledge this and to consequently stop brand substitution of AEDs under law. For further information in support of exempting AEDs from substitution clink on the following link http://www.ncbi.nlm.nih.gov/sites/entrez If you support the AEDs being exempt from brand substitution in Australia please 'sign' below and let all your friends know about the petition too. This petition will be forwarded to Nicola Roxon, The Minister for Health and Aging and we will continue to petition the government until suitable change is achieved.
