Introduction

For over 20 years, bupropion has been used as an antidepressant by inhibiting the norepinephrine-dopamine reuptake. Hyponatremia is a relatively rare condition that has been associated with the use of antidepressants including selective serotonin reuptake inhibitors (SSRIs), serotonin norepinephrine reuptake inhibitors (SNRIs), and tricyclic antidepressants (TCAs). However, a few case studies have reported that bupropion was associated with hyponatremia.

Objectives and aims

To review available literature on bupropion-induced hyponatremia and its possible underlying mechanisms.

Methods

Case studies are presented and discussed followed by a literature review.

Results

Hyponatremia has been reported with the use of many antidepressants, however, studies on bupropion induced hyponatremia has been limited. In literature only four case reports have been presented. Typically, this condition is only seen in frail or elderly patients. Possible mechanism is that bupropion may cause hyponatremia by the noradrenergic stimulation of vasopressin release.

Conclusion

Clinicians should be aware of increased risk of hyponatremia associated with antidepressants, including bupropion. Especially in the elderly, clinical symptoms of hyponatremia can be misinterpreted and may lead to a life-threatening condition.
