Lilly Sues Two Compounders Over Copies of Weight-loss Drugs

April 2, 2025

Eli Lilly said on Tuesday it had sued two mass compounders for selling unapproved products that contain tirzepatide, the main ingredient in its popular weight-loss and diabetes medicines.

This comes after a U.S. federal judge last month refused to allow compounding pharmacies to keep making copies of these drugs in the United States.

Compounders had been allowed to produce hundreds of thousands of doses of copies of obesity drugs only while the FDA said there was a shortage of them.
