Merck's Language Experience

We want you to have the best possible experience with our site in your preferred language. While most of our pages and features are available in both English and Japanese, there are some localized pages only available in Japanese, such as this one.

If you would like to view this page in Japanese, switch your current language choice from EN to JA. This drop-down feature is located on the top right of the page.

If you change your selection for this particular page, but prefer English as your default language, switch back to English after this session.

We are continuously working to improve the language experience on our site so that you can make browsing and purchasing choices in your preferred language. If you run into additional problems, our customer support team is available to help.
