Our commitment to your safety: Pharmacovigilance

Discover the process of how we monitor our medicines

At Genentech, we take your safety very seriously. That's why we monitor the safety of our medicines during clinical trials and after—a process called pharmacovigilance. In this video, you'll see the steps we take to monitor the safety of our medicines once they are available for use. You'll also learn how to report any adverse event (any issue that arises when someone is taking a medication, even if the connection between the event and the medication is not obvious) or potential side effect.

There are 3 key components to pharmacovigilance:


Over 2000 employees monitor and analyze reports of adverse events from healthcare providers and people like you.


We partner with the community to collect global data that are studied in aggregate to look for patterns. This gives us the clearest, most robust, and constantly evolving picture of how a medicine is working in a real-world setting.


If we identify that the balance of benefit to risk of a medicine has changed, our team quickly takes action. We proactively notify the FDA, update the package insert or label if appropriate, and communicate the new information to healthcare professionals and the community.
