Sanofi got a ton of free press last week from hundreds of thousands of Twitter users. To update the (blissfully) uninformed, comedian Roseanne Barr had recently used the social media platform to make a racist statement about a former White House aide. Presumably in damage control mode afterwards, Barr tweeted an apology saying she had been “Ambien tweeting.” So Sanofi—who makes Ambien—had the opportunity to engage in some, uh, brand management. The company’s response thus makes very clear that, “While all pharmaceutical treatments have side effects, racism is not a known side effect of any Sanofi medication.” Their tweet blew up, with nearly 69k retweets and over 185k likes. And while they note no Sanofi medication has side effects of racism, they weren’t clear on other companies’ drugs. Your move, social media managers.
