Bupropion-Associated Irritability in Older Adults With Dementia
Bupropion can precipitate neuropsychiatric changes, including irritability, hostility, and agitation, especially early in treatment or after dose changes. [1] These symptoms can worsen pre-existing behavioral symptoms common in dementia. [1]
Core Neuropsychiatric Adverse-Effect Signal
Bupropion labeling includes risk of anxiety, agitation, insomnia, irritability, hostility, aggressiveness, impulsivity, akathisia, and unusual behavior changes. [1] These neuropsychiatric symptoms are emphasized as requiring day-to-day caregiver monitoring during early treatment and during dose adjustments. [1]
Clinical Relevance to Dementia Presentations
Dementia commonly involves behavioral and psychological symptoms that can overlap with antidepressant-induced neuropsychiatric adverse effects. [1] A new or abrupt increase in irritability or agitation after starting bupropion or changing the dose is consistent with the labeled adverse-effect pattern. [1]
Initiation-Period Monitoring Considerations
Close monitoring is recommended for emerging irritability, hostility, agitation, or other unusual behavioral changes, particularly early after initiation and around dose changes. [1] Severe or abrupt-onset behavioral changes should trigger prompt reporting to the prescribing clinician and possible medication changes. [1]
Practical Medication-Management Implications
If irritability or agitation occurs after starting bupropion or after a dose increase, the medication is a potential contributor based on the labeled warning symptoms. [1] Discontinuation should be clinician-directed because sudden cessation of antidepressants can cause additional symptoms. [1]
Key Documentation for Care Teams
Caregiver observation should track timing relative to bupropion initiation and dose changes. [1] Documentation should include severity, onset pattern, and whether symptoms represent a departure from the patient’s baseline dementia behaviors. [1]
