Quetiapine dependence and withdrawal: a case report
1Deaprtment of Psychiatry, Istanbul University, Istanbul, Turkey. iyargic@hotmail.com
This study reports the first confirmed case of quetiapine dependence in a patient with a history of substance abuse. Quetiapine dependence requires caution when prescribing to patients with addiction disorders.
Area of Science:
- Psychiatry
- Addiction Medicine
- Clinical Pharmacology
Background:
- Quetiapine, a second-generation antipsychotic, is approved for schizophrenia and bipolar disorder.
- Reports suggest potential for quetiapine abuse and dependence.
- This study details the first confirmed case of quetiapine dependence.
Observation:
- A 37-year-old male presented with uncontrolled quetiapine use.
- He had a history of alcohol and benzodiazepine dependence and cannabis abuse.
- The patient reported euphoric effects ('rush') and withdrawal symptoms upon attempting to reduce quetiapine dosage.
Findings:
- This case represents the first documented instance of definite quetiapine dependence.
- The patient experienced significant distress and loss of control over quetiapine consumption.
- Withdrawal symptoms were noted upon dose reduction, indicative of physiological dependence.
Implications:
- Quetiapine, while potentially useful in treating addiction comorbidities, warrants careful consideration in patients with existing substance use disorders.
- Clinicians should be vigilant for signs of quetiapine misuse and dependence, particularly in vulnerable populations.
- Further research is needed to understand the full spectrum of quetiapine's addictive potential and inform clinical guidelines.

Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...
