What Is a Cookie?

A cookie is a small amount of data that is sent to your web browser from a web server. This data is never executed as code, so it can't contain programs or viruses, and can't be longer than 4,000 characters. Cookies are generally used to help websites determine if you have been to the site before and what, if any, actions you have taken on the site.

Let's say, for example, that you go to a shopping website and purchase something. Instead of going off to pay for that item right away, you want to continue browsing. A cookie can be set to indicate that you put something in your shopping cart. When you go to pay for all your items, the server knows all the items you selected by looking at your cookie.

Merck & Co., Inc., uses cookies confirm that you have identified yourself as a resident of the United States. We do this in accordance with statutes that regulate information related to prescription medicines. We do not distribute your cookie information to other organizations. No other sites can access this cookie.

What About Security?

A cookie cannot be used to extract data from your system. When a cookie is set, your browser checks the domain from which it came. This domain check means that only Merck & Co., Inc., can access your Merck cookie.
