Why am I blocked from accessing ClinicalKey content?

When I try to access content on ClinicalKey, I get a message:

Sorry, you have been blocked
You are unable to access clinicalkey.com

 

 

 


Answer

Reason

This is a perceived security issue detected directly by Elsevier ClinicalKey's systems.

Solution 1: Browser Cookies

Try going to your web browser's settings and clearing (deleting) the cookies and cached files "for all time". Then, close and restart the browser and try again to access ClinicalKey. 

Solution 2: Contacting ClinicalKey

Please send your report to ClinicalKey by using the link below (select the Main or PDC link depending on your affiliation). They'll need to ask you some questions before restoring your access -- often it's a perfectly innocent false positive.
