This sounds like a fantastic idea to me.

WASHINGTON, Nov 9 (Reuters) – A drug industry group on Monday urged the U.S. Food and Drug Administration to adopt a universal safety symbol for Internet content containing FDA-approved information about a medicine or medical device.

The proposal from the Pharmaceutical Research and Manufacturers of America, which represents some of the biggest drug makers in the world, came ahead of an FDA public meeting this week on how FDA-regulated prescription drugs and medical devices are promoted in social media and on the Internet.

PhRMA said the logo would be coupled with a link leading Web users to FDA-regulated information about the device or drug. Whether that link would go to the FDA’s or drug maker’s site or another forum is up for debate

My personal preference is for the link to go to the FDA web site, although I’d be OK with it going to the drugmaker if they had to keep the linked page up for as long as the drug is on the market.
