Legembi - FDA Prescriptive Information

The F.D.A. included narrower and more cautionary language on the drug label than it initially had with Aduhelm. The Leqembi label says the drug should be used only for patients in early and mild stages of Alzheimer’s disease, matching the status of patients in the clinical trials of the drug. It instructs doctors not to treat patients without doing tests to confirm that they have one of the hallmarks of Alzheimer’s: a buildup of the protein amyloid, which Leqembi is designed to reduce.
