Thanks Richard. http://thinkstrategy.com/contact/ is one of the URL's listed as being related to "prescription".
I did read how this is a sign of hacking, but I didn't see any other signs. I couldn't see anything injected or any new pages created. I checked to see if the site was distributing malware (http://www.google.com/safebrowsing/diagnostic?site=mysite.com) and it was not listed as impacted yet. No notices in webmaster tools for being impacted (Google or Bing) yet.
