Summary
Paroxetine, an antidepressant, was linked to three fatal overdoses. These cases highlight potential risks, including interactions with other substances and drugs, emphasizing the need for careful monitoring.
Area of Science:
- Forensic Toxicology
- Clinical Pharmacology
Background:
- Paroxetine is a selective serotonin reuptake inhibitor (SSRI) antidepressant.
- It is prescribed for depression, obsessive-compulsive disorder, and panic disorder.
- Limited data exists on paroxetine overdose toxicity.
Observation:
- Three fatal cases involving paroxetine overdose were reviewed by coroners.
- Case 1: Paroxetine was the sole detected drug (4.0 mg/L).
- Case 2: Involved alcohol and paroxetine (3.7 mg/L) with other antidepressants.
- Case 3: Suggested paroxetine-imipramine/desipramine interaction (1.4 mg/L paroxetine).
Findings:
- Paroxetine was directly associated with the cause of death in all three cases.
- Toxicology confirmed significant paroxetine levels in postmortem samples.
- Drug interactions and co-ingestions complicated the overdose scenarios.
Implications:
- These cases underscore the potential lethality of paroxetine overdose.
- Highlights the importance of considering drug interactions and co-ingestions in overdose cases.
- Suggests the need for increased awareness and caution in prescribing and managing paroxetine, especially in vulnerable patients.
