Lawsuits have blamed the highly caffeinated drink for at least two deaths.

A Panera Bread spokesperson says the restaurant chain is phasing out its Charged Lemonade, a highly caffeinated beverage that has been blamed for at least two deaths in lawsuits.

The beverages prompted controversy in October following a lawsuit filed by the family of 21-year-old Sarah Katz, a University of Pennsylvania student with a heart condition who died after consuming Charged Lemonade. A second lawsuit was filed in December by the family of Dennis Brown, a Florida man with a chromosomal deficiency disorder and a developmental delay who also died after drinking a Charged Lemonade.

A third lawsuit was filed in January by Lauren Skerritt, a 28-year-old Rhode Island woman, which claimed the beverage left her with “permanent cardiac injuries.”
