Cookie policy

This Cookie Policy may be amended by us at any time. Please check this page periodically to inform yourself of any changes.

This Cookie Policy was most recently updated in February 2022.

1. Cookies – what are they?

A “cookie” is a small text file that’s stored on your computer, tablet or phone when you visit a website. We may collect information from you by using “cookies”. A cookie will contain some anonymous information, such as a unique identifier and the site name, and some digits and numbers.

Some cookies are deleted when you close down your browser. These are known as session cookies. Others remain on your device until they expire or you delete them from your cache. These are called persistent cookies and they enable us to remember things about you as a returning visitor.

2. How we use cookies

We use the following types of cookies on this website, www.dupixent.co.uk (the “Site”):

  • Strictly necessary cookies. These are cookies that are required for the operation of this Site. They include, for example, cookies that enable you to log into secure areas of our website.
  • Analytical/performance cookies. These are a type of persistent cookie (as explained in the Cookies - what are they?section above). They allow us to recognise and count the number of visitors and to see how visitors move around the Site when they are using it. This helps us to understand what people do and don't like about the Site so it can be improved, for example by ensuring that users are finding what they are looking for easily. Since Google started providing its own analytics technology free of charge to website owners, almost all websites use some form of it - although there are also paid-for services available to rival Google's service. Analytical cookies are probably the most common form of cookies in use today.

You can find more information about the individual cookies we use and the purposes for which we use them in the Cookies we use section below.

Please note, third party links or advertising on this Site may also use cookies, over which we have no control; you may receive these cookies by clicking on the link to the third party site or advertising. We do not control the collection or use of information by these third parties and these third party cookies are not subject to our Privacy Policy.

4. What to do if you don’t want cookies to be set

Some people find the idea of a website storing information on their computer or mobile device a bit intrusive, particularly when this information is stored and used by a third party without them knowing. Although this is generally quite harmless, you may not, for example, want to see advertising that has been targeted to your interests (although no such cookies are used on this Site).

If you prefer, it is possible to block cookies, by changing a setting within your web browser that allows you to refuse the setting of all or some cookies, or to delete cookies that have already been set. The “help” section of your browser will tell you how to prevent your browser from accepting cookies. We have included further details on how to manage cookies on popular browsers in the Managing cookie settings section below. However, please note, if you use your browser settings to block all cookies (including essential cookies), you may not be able to access all or parts of this Site.
