Encaprin

Encaprin is a now-defunct brand of ibuprofen-based drug manufactured by Procter & Gamble in the mid-1980s.

Contamination hoax

In 1986 a hoax was started by an anonymous source, after an unidentified caller phoned Procter & Gamble claiming he had placed cyanide-filled capsules of Encaprin in pharmacies in Chicago and Detroit, leading many stores, including Walgreens, to remove the product from their shelves. Advisory cautions were issued although many assumed it was a hoax from the beginning.[1]
