FDA Removes Suicidal Thought Warnings From GLP-1 Drugs

In a move that clears a significant regulatory hurdle for the pharmaceutical industry, the U.S. Food and Drug Administration (FDA) has directed drugmakers to remove label warnings regarding potential suicidal thoughts from several popular weight-loss medications. The request applies to blockbuster GLP-1 receptor agonists, specifically Novo Nordisk’s Wegovy and Saxenda, and Eli Lilly’s Zepbound.
The FDA’s decision follows a comprehensive review of 91 clinical trials involving 107,910 patients. Of those participants, over 60,000 received a GLP-1 drug while the remainder received a placebo. The analysis concluded there was no evidence linking these medications to an increased risk of suicidal behavior, ideation, or other psychiatric side effects such as anxiety, depression, or psychosis.
GLP-1 receptor agonists, which were originally developed to treat type 2 diabetes, work by mimicking a gut hormone that suppresses appetite and creates a feeling of fullness. While the diabetes versions of these drugs never carried such warnings, the obesity-specific versions did. Federal regulators noted that this update will ensure "consistent messaging" across the labels of all FDA-approved GLP-1 medications.
This final determination puts to rest concerns raised during a preliminary review in 2024. While that earlier assessment also found no link, officials stated at the time that they could not completely rule out a small risk due to limited data. The new, more robust analysis has now "put those concerns to rest".
The ruling is expected to lift a "cloud" over these drugs, which have seen surging global demand in recent years. Similar reviews conducted in the United Kingdom in 2024 reached the same conclusion, finding no causal link between the medication class and suicidal thoughts. Both Eli Lilly and Novo Nordisk did not immediately comment on the regulatory update.
