Wal-Mart must pay $1.27 million to the family of an Arkansas man who died after a pharmacist gave him the wrong medication. John Tucker died in September 1997 after taking Ziac, a high blood-pressure drug, instead of Zaroxolyn, a diuretic. A labeling mistake on the prescription bottle caused the fatal error. Fluid accumulated in Tucker's body causing severe weight gain. After several months of taking the wrong medication, he eventually died of congestive heart failure.
