Information Automatically Collected
When you visit any website, the site can automatically collect information about your visit. When you browse through our site, read pages there, or download information, we collect certain information to measure how many visitors come to the different parts of the site so we can make the site more useful.
Example: We use browser information to help us design our site so the greatest number of people can view the pages correctly.
For every visitor, we collect and temporarily store the following information:
- Your computer's Internet Protocol (IP) address.
- The domain from which you access the Internet.
- The website address from which you came to our site.
- The date and time you arrived at our site and how long you spent there.
- The name and version of your computer's operating system and browser.

We use this information to improve our website and provide a better experience for our visitors. We use tools, Google Analytics, to aggregate this information.

Web Measurement and Customization
The Office of Management and Budget (OMB) Memo M-10-22, Guidance for Online Use of Web Measurement and Customization Technologies allows Federal agencies to use web measurement and customization technologies such as session and persistent cookies.
Some services on our website use session cookies. These are:
- Small bits of text temporarily stored in your computer.
- Used to aid searching and navigating the site.
- Deleted when you close your browser.
As defined by OMB, our use of session cookies is "Usage Tier 1—Single Session." Tier 1 uses encompass "any use of single session Web measurement and customization technologies." Data collected through our session cookies will be retained only for as long as needed to use for the measurement purposes.
Some services on our website use multi-session cookies, also known as persistent cookies. Persistent cookies are:
- Small bits of text temporarily stored in your computer.
- Placed on your computer for more than a single session.
- Used to differentiate between new and returning site visitors, to customize our website for frequent visitors, and to assess site design and content.
Persistent cookies placed on your computer will expire two years after your last visit to our website. Data collected through persistent cookies will be retained by the specific FDA office associated with the website using the cookie.
OMB defines our use of persistent cookies as "Usage Tier 2—Multi-session without Personally Identifiable Information (PII)." This applies to “any use of multi-session Web measurement and customization technologies when no PII is collected."
Use and Sharing of Cookie Data
We do not use session cookies or persistent cookies to collect PII and we do not share any data collected from cookies.
How to Opt-Out or Disable Cookies
Both session and persistent cookies pertaining to our website are enabled by default because of their integration with our website. If you do not wish to have session or persistent cookies placed on your computer, you can disable them using your Web browser.

- If you submit a form on our website, we will receive only the personal information you include in the form.
- Children's Privacy: We collect no information from children under 13. If a child sends us an email inquiry or comment, we will answer it, and then delete the email from our files.

FDA Information Disclosure Policy
FDA will not disclose, give, sell, or transfer any personally identifiable information (PII) about our visitors unless it is required:
- By law or regulation.
- For law enforcement reasons.
Other possible uses of your information:
- We may use PII to respond to you, in which case various people may need to see the information you provide in order to provide a response to you. If enough questions or comments come in that are the same, your question (but not your name) may be added to our Questions and Answers section. We use this information to help us improve our site.
- We may enter information you send into an electronic database to share with attorneys or investigators involved in law enforcement or policy-making.
- We may share information with other government agencies that have public health or consumer protection duties, in which case FDA or any of those agencies may contact you.
- In other limited circumstances, including requests from Congress or private individuals, we may be required by law to disclose information you submit.
Links to Other Sites
Reference in any referred (linked) website to commercial products, services, manufacturers, or companies does not constitute an endorsement by the U.S. government, the Department of Health and Human Services, or FDA.
FDA is not responsible for the contents of any pages referred from its website.
Third-Party Websites and Applications
In addition to FDA’s official website on www.fda.gov, FDA uses social media and third-party (non-FDA) websites to share information and to engage with the public. For example, there may be third-party applications and/or services linked to or embedded on www.fda.gov to improve its functionality. Likewise, applications created by FDA may be embedded on third-party websites as a way to increase public awareness of FDA activities. Our integration of these products is intended to provide a seamless user experience and to enhance users’ ability to access information and communicate with FDA.
Some third-party websites and applications may make personally identifiable information (PII) available to the public and/or FDA based on user controlled settings or the privacy policies of the third-party. FDA will not collect, maintain, use, or share any PII that becomes available through FDA’s use of third-party websites or applications.
FDA conducts and publishes a Privacy Impact Assessment (PIA) for each use of a third-party website. Each use of a third-party website may have unique functionality or practices. To learn more, review the published PIAs at http://www.hhs.gov/pia/.
The health and medical information on our website is not intended to take the place of advice or treatment from healthcare professionals. It is also not intended to substitute for the users' relationships with their own health care/pharmaceutical providers.
The Code of Federal Regulations is the authoritative source for FDA regulations.
FDA is dedicated to:
- Ensuring that all information it publishes reflects a level of quality corresponding to the nature and timeliness of the information.
- Disseminating all its data as broadly and promptly as possible so that the public can benefit from FDA's mission to promote and protect the public health.
Note: In keeping with this commitment and in accordance with Public Law 106-554 and Office of Management and Budget requirements, HHS and FDA have developed information quality guidelines establishing quality assurance policies, standards, and processes.
The HHS guidelines are available at http://www.hhs.gov/infoquality/.
Linking to or Copying Information on the FDA Website
Unless otherwise noted, the contents of the FDA website (www.fda.gov) — both text and graphics — are not copyrighted. They are in the public domain and may be republished, reprinted and otherwise used freely by anyone without the need to obtain permission from FDA. Credit to the U.S. Food and Drug Administration as the source is appreciated but not required.
People are also free to link to any URL on FDA's site. FDA's preference is that people link to the material on the FDA site (rather than copying it to their personal websites) because the agency continuously updates the information on the website as better information becomes available. A person copying documents to another website, instead of linking to them, would then have to monitor the original documents to know when these documents were updated by FDA or else risk giving bad or incorrect advice to visitors to their website. Providing consumers or health professionals with advice that is not fully up to date can lead to serious public health consequences. Providing industry advice that is not fully up to date can lead to companies being out of compliance with regulatory requirements.
If a person, nonetheless, decides to copy content or images, FDA strongly recommends that the copied item lists the date that the material was copied and provides a link back to its source on the FDA website. Users can then see for themselves if the copied material has been updated or changed.
FDA appreciates being informed about the use of website materials. Please email us at [email protected]

FDA is working to complete the transition to Internet Protocol Version 6 (IPv6), based on OMB-M-21-07. More information can be found on the HHS web site: HHS Policy For The Transition To Internet Protocol Version 6 (Ipv6) | HHS.gov
When visiting our website, your web browser may produce pop-up advertisements.
