We want to let you know that the changes to our pharmacy policy in the U.S. and Canada will start to go into effect today.

As we explained a couple weeks ago, this update means that Google AdWords will only accept advertisements from VIPPS and CIPA certified pharmacies, and that these pharmacies can only target ads within the countries where they are accredited.

To ensure that users see the most relevant and useful ads possible, pharmaceutical manufacturers and VIPPS and CIPA certified pharmacies will be allowed to run on prescription drug and pharmaceutical-related keywords.
