Cookie Policy


We automatically process certain types of information whenever you interact with us on our online services and in some emails we may send to you. Automatic technologies we use may include, for example, cookies and web beacons.

  • Cookies: A cookie is a piece of information that is placed on your computer when you access certain websites. The cookie uniquely identifies your browser to the server. Most web browsers are set up to accept cookies, though you can reset your browser to refuse all cookies or to indicate when a cookie is being sent. Note, however, that some portions of our websites may not work properly if you refuse cookies.
  • Web Beacons: On certain websites or emails, Alexion may utilize a common Internet technology called a “web beacon” (also known as a “pixel tag”, an “action tag”, or “clear GIF technology”). Web beacons help analyze the effectiveness of advertising campaigns and websites by measuring, for example, the number of visitors to a site or how many visitors clicked on key elements of a website.

Do Not Track (DNT) is a privacy preference that you can set in certain web browsers. Our websites may not recognize or respond to DNT signals, as the industry is currently working toward defining what DNT means and developing a common approach to responding to DNT signals. You can learn more about DNT here.
