Multiple lots of weight-loss medication Wegovy were recalled by pharmaceutical giant Novo Nordisk because hair was found in a prefilled syringe, according to two notices published by the Food and Drug Administration (FDA) this week.

The recall entails lots of four Wegovy, or semaglutide, single-dose prefilled pens in 0.5 mg/0.5 mL doses, according to an FDA notice issued on Dec. 31. The other notice, published on the same day, said that four Wegovy single-dose prefilled pens at 1 mg/0.5 mL doses are also under recall.
