Report a Side Effect

Please select your country of citizenship from the list below to report an adverse event for a Bayer Pharmaceutical or Personal 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 Personal Health products, your support is pivotal, whether you are a customer, patient or healthcare professional.

Depending on your selected country / location, you will be directed to Bayer’s tool SafeTrack – a web-based tool made for patients, caretakers and healthcare professionals to conveniently report adverse events digitally. When you select English, Japanese, Portuguese or Spanish as language you can also report using our virtual assistant.

Bayer takes the protection of personal data very seriously. We adhere to applicable national and European data protection regulations and will collect and process any personal data that you provide in accordance with our pharmacovigilance data privacy policy.
