Johnson & Johnson defeated a lawsuit claiming it had improperly designed its Tylenol pain reliever in the first case to go to trial over the link between the widely used over-the-counter drug and liver damage, according to a J&J spokesman. Jurors in New Jersey concluded that Regina Jackson, a state employee who said she spent a week in the hospital after overdosing on Extra Strength Tylenol, failed to prove her case, according to J&J spokesman Jake Sargent.
