The U.S. Food and Drug Administration on Friday agreed to reconsider its recent decision barring drug compounders from selling their own versions of Eli Lilly's blockbuster weight loss and diabetes drugs.

There’s a war brewing over blockbuster weight loss medications — and patients are now getting caught in the crossfire.

The two-year shortage of Eli Lilly’s blockbuster weight-loss and diabetes drugs is over, the U.S. Food and Drug Administration announced Wednesday.

Some patients fear that they’ll lose access to tirzepatide because the US Food and Drug Administration determined that a shortage of the brand-name drug has ended – which means compounding of the medicine must stop.

The FDA, in a stark reversal, on Friday said it would reconsider its decision to remove Eli Lilly’s tirzepatide from its shortage list.

With the resolution, compounding pharmacies are no longer able to produce tirzepatide. And the FDA highlighted the point to the drug makers, writing in bold that the agency "reminds compounders of the legal restrictions on making copies of FDA-approved drugs."

The U.S. Food and Drug Administration removed Eli Lilly's blockbuster weight-loss and diabetes drugs from its shortage list late on Wednesday, likely piling pressure on firms selling cheaper versions known as compounded drugs.

The FDA says the shortage of tirzepatide injection — a glucagon-like peptide 1 medication used for diabetes and weight loss — has been resolved.

Eli Lilly (LLY) is calling on companies that have been selling off-brand versions of its popular diabetes and weight-loss drugs during widespread shortages to halt production now that supplies are stabilizing.
