Eli Lilly Wednesday filed lawsuits against four telehealth companies alleging they are deceiving consumers by selling compounds of slightly-different versions of Lilly drugs.

The drug company Eli Lilly is suing four telehealth companies for allegedly selling copies made by compounding pharmacies of its drug Zepbound.

Pharmaceutical giant Eli Lilly alleges the companies are selling illegal off-brand versions of its best-selling diabetes and weight-loss drugs, Mounjaro and Zepbound.
