GLP-1 Agonists Linked to Lower Antidepressant and Addiction Drug Starts
This Australian prescription sequence symmetry analysis offers real-world signal-detection evidence that GLP-1 receptor agonist initiation precedes reduced starts of antidepressants and substance use disorder medications, informing pharmacists' understanding of the evolving neuropsychiatric profile of these agents.

GLP-1RAs linked to reduced need for antidepressants and addiction medications.
There is conflicting evidence regarding the neuropsychiatric effects of glucagon-like peptide-1 receptor agonists (GLP-1RAs), so understanding their impact on mental health is important. Initiation of GLP-1RAs was inversely associated with starting antidepressants (adjusted sequence ratio (aSR): 0.85; 95% confidence interval (CI): 0.76-0.94) and medications for substance use disorder (aSR: 0.70; 95% CI: 0.51-0.88). These findings suggest that GLP-1RAs might lower the need for certain neuropsychiatric medications, although further investigation is required to confirm these associations. GLP-1RAs may reduce the likelihood of initiating antidepressants and substance use disorder medications.
