Genentech Medical Twitter Community Guidelines

Welcome to the Genentech Medical Twitter page! This page is intended for US Healthcare Professionals only.

This Twitter page has been created by Genentech Medical Affairs as a forum to share scientific information. This includes, but is not limited to, medical information, disease education, research updates, and clinical trial information that may be investigational in nature. The information presented on the Genentech Medical Twitter page does not imply US FDA approval and should not be construed as a recommendation for use.

There are regulations in our industry that regulate what can and cannot be said on our Twitter page. As a result, all @mentions, comments, replies, pictures, and videos posted on this Twitter page will be moderated. Tweets that are offensive, threatening, or violate our Community Guidelines will not be shown on our page and may result in the user getting blocked from this Twitter page and/or reported to Twitter.

Please review and familiarize yourself with the rules below before you post any comments or replies to this Twitter page. Generally, we will respond to comments or replies to our Tweets at the earliest opportunity but will not respond to comments or replies to our Tweets that violate our Community Guidelines or Twitter Terms of Service.

Join the conversation.

We want you to be part of the community. We welcome your comments and replies on our Twitter page as long as you follow our Community Guidelines. If your comment or reply is off-topic, confusing or misleading, or violates our Community Guidelines, it will not be shown on the page.

Since we have to be mindful of the regulations that govern our industry, please do not post any comments or replies that reference Genentech products and services or those of our competitors.

Report adverse events.

If you are aware of anyone that has experienced any adverse events related to Genentech products, we encourage you to report them immediately to Genentech Drug Safety by emailing [email protected] or calling 1-888-835-2555. You can also contact the FDA directly by visiting or calling 1-800-FDA-1088. If your comment or reply includes an adverse event that anyone you are aware of has experienced while taking a Genentech product, we will follow required processes to report this adverse event to the FDA and you may be contacted with questions or for additional information.
