Hallucination, other psychotic symptoms after stopping GLP-1s: report
Key Points:
- Over half of patients discontinue GLP-1 medications within their first year, often due to high costs, side effects, or satisfaction with weight loss, but stopping these drugs usually leads to rapid weight regain.
- New case reports highlight serious psychiatric effects after stopping tirzepatide, a GLP-1 drug, including hallucinations, paranoia, and psychotic disorders in a 61-year-old man, and manic episodes with erratic behavior in a 52-year-old man.
- Research indicates GLP-1s influence brain circuits involved in mood and reward processing by affecting dopamine pathways, which may explain these psychiatric symptoms after discontinuation.
- Both patients had pre-existing mental health conditions, suggesting that underlying psychiatric history may increase vulnerability to adverse effects when stopping GLP-1 therapy.
- Experts call for greater awareness among clinicians about potential psychiatric side effects after GLP-1 cessation and advocate for further research into the drugs' impact on brain function.
