Report an Adverse Event

Patient safety is paramount to us, and we manage safety data relating to our treatments with the utmost rigor. While Gilead continuously evaluates the safety of our treatments, it is often not possible to detect every potential side effect associated with a medicinal product during clinical trials, so it is important to continue to report safety data once a product is authorized. Collecting safety information from patients, healthcare providers and customers helps enable us to continually monitor the benefit and risk profiles of our medicinal products.

If you have a general question about Gilead medicines, please visit the Gilead Medical Information site.

Please select your country from the list below for information on how to report a potential adverse event:
