Nearly half of all US.(Update)(Brief article)

Nearly half of all US adults--48%, or 112 million--used the internet for drug information in 2010, according to Manhattan Research, which found that older consumers are now joining their younger counterparts in searching for medical info online. That's more than double the 55 million Americans searching for drug info online in 2005. The research firm said it found that consumers are more likely to discuss the information they glean online with their doctors than they are to act unilaterally on it, and consumers "are considerably more likely to use pharma product and corporate websites for prescription drug information than government websites, pharmacy websites, patient association websites and social media sources."
