Preferred Contact Method

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 products, your support is pivotal, whether you are a customer, patient or healthcare professional. 


If you want to report a side effect or quality complaint, please contact your healthcare professional (e.g. physician or pharmacist) or your local health authority. 


Reports can also be made on our Side Effect Reporting website.
