During the 2001 anthrax attacks, thousands of Americans who were possibly exposed to the deadly bacteria were given a powerful antibiotic, Cipro.
The drug, developed by Bayer HealthCare, was literally a lifesaver during the crisis — especially for vulnerable postal workers and Capitol Hill staffers. Many who weren't even at risk also obtained prescriptions simply for piece of mind. In New York City, for instance, demand became so great that many pharmacies could fill only 10-day orders of the drug.
At the height of the crisis, fearing that there wouldn't be enough Cipro in the event of a national outbreak, the U.S. government decided to purchase more than 100 million doses of the drug. By the end of the ordeal, Cipro was a household name and widely credited with helping avoid an even greater public health catastrophe.
