////// Science for a better life Global Breadcrumb Pharmaceuticals Report a Side Effect Patient And Drug Safety Report a Side Effect Please select your country of citizenship from the list below to report an adverse event for a Bayer Pharmaceutical or Consumer Health product. Humans vary in their biological reactions to medicinal products. This is why not all adverse reactions (side effects) associated with the use of medicinal products can be detected during clinical development, not even by the most comprehensive clinical trials. Capturing as many of these adverse reactions, however rare they may be in absolute terms, from worldwide sources is of paramount importance for continued patient and drug safety (pharmacovigilance). For Bayer as a global pharmaceutical company, pharmacovigilance takes center stage, beyond mere compliance with worldwide regulations. To enable Bayer to provide up-to date safety information on Bayer Pharmaceutical and Consumer Health products, your support is pivotal, whether you are a customer, patient or healthcare professional.
