Description
Combining duloxetine and sertraline, two serotonergic antidepressants, markedly increases the risk of serotonin syndrome without added efficacy.
Mécanisme
Both agents inhibit SERT; duloxetine additionally inhibits NET, resulting in robust serotonergic and noradrenergic excess when combined.
Signification clinique
Dual antidepressant therapy of this type is not evidence-based and carries significant serotonin toxicity risk.
Prise en charge
Avoid concurrent use; if augmentation is needed, consult a psychiatrist for evidence-based strategies.
