Claimant: Dr. Marty Makary
Claim: A new FDA label change for leucovorin would benefit “hundreds of thousands of kids” with autism.
Rating: MISLEADING
Explanation: The FDA expanded leucovorin’s label only for a rare genetic condition known as cerebral folate deficiency caused by a specific mutation. The condition affects about 1 in 1 million people, or roughly 70 children in the United States. The FDA did not approve leucovorin as a treatment for autism, and evidence supporting broad benefits for children with autism remains limited.
