By the end of their first year on GLP-1s, more than half of patients stop taking the medication.

There are a number of reasons for this, including high costs, unpleasant side effects and satisfaction with the weight they’ve already lost. The catch: stop taking GLP-1s, and the weight is likely to come back fast.

Research is just beginning to uncover the psychiatric impacts of stopping a drug that could be affecting how the brain processes mood and rewards.

New case reports published in The Primary Care Companion CNS Disorders detail the stories of two men who suffered psychiatric effects after stopping the weight loss drug.

A 61-year-old man stopped tirzepatide (sold under the brand names Mounjaro and Zepbound) in August 2025 because of nausea.
