For an 82-year-old female in a memory‑care unit with Alzheimer’s disease, mild cognitive impairment, anxiety disorder, acquired hypothyroidism, Graves’ disease, pulmonary fibrosis, insomnia, hypertension, and prior hip replacement, who is taking Celexa (citalopram) 40 mg daily, Wellbutrin XL (bupropion) 150 mg daily, and trazodone 50 mg at bedtime, and who is frequently agitated, refuses nighttime medication about half the time and repeatedly takes daytime doses, should her psychotropic medications be discontinued or is it acceptable to miss up to half a dose per month, and will missing doses worsen her symptoms?

Simplify and Consolidate Her Medication Regimen Immediately

Given this patient's poor medication adherence (refusing ~50% of doses), frequent agitation, and advanced dementia (alert and oriented x1 only), you should discontinue or dramatically simplify her psychotropic regimen rather than continue medications she's not reliably taking. Inconsistent dosing of SSRIs and bupropion can worsen agitation and behavioral symptoms due to discontinuation effects, making the current situation counterproductive 1.

Why Inconsistent Dosing is Harmful

Missing doses of Celexa (citalopram) causes discontinuation syndrome that includes dysphoric mood, irritability, agitation, anxiety, confusion, and emotional lability 1. These withdrawal symptoms likely contribute to—or even cause—the combative behavior you're observing. When she refuses her medications half the time, she's essentially cycling through mini-withdrawals repeatedly, which is worse than never starting the medication at all.

Immediate Action Plan

1. Prioritize Non-Pharmacologic Interventions First

Before continuing or restarting any psychotropic medications, the APA guidelines mandate assessing and implementing person-centered nonpharmacological approaches 2. You need to:

• Assess for pain and modifiable contributors (constipation, urinary retention, environmental triggers, unmet needs) 2
• Quantify the agitation using a standardized measure (Cohen-Mansfield Agitation Inventory or similar) 2
• Implement behavioral interventions: redirection, structured activities, music therapy, consistent caregiving staff 2, 3

2. Taper and Discontinue Celexa and Wellbutrin

Rationale:

• She's not taking them consistently anyway, creating a harmful cycle of partial withdrawal
• Neither medication has strong evidence for treating agitation in dementia
• Celexa at 40 mg in an 82-year-old carries significant risks (hyponatremia, falls, QT prolongation) 1
• Bupropion can be activating and may worsen agitation in dementia patients

How to taper:

• Reduce Celexa by 10 mg every 5-7 days (40→30→20→10→off) to minimize discontinuation symptoms 1
• Discontinue Wellbutrin XL more rapidly (can stop over 1-2 weeks) as it has less severe discontinuation effects

3. Optimize Trazodone for Sleep and Agitation

Trazodone is the one medication worth continuing because:

• It has evidence for improving sleep in Alzheimer's patients (42.5 additional minutes of sleep per night) 4
• It may slow cognitive decline when used for sleep 5
• It's effective for agitation and behavioral symptoms in dementia 6
• It's generally well-tolerated in older adults with dementia 6, 4

Practical adjustment:

• Keep trazodone 50 mg at bedtime
• If she refuses it, do not force the issue—missing occasional doses of trazodone is far less problematic than missing SSRI doses
• Consider increasing to 100 mg if agitation persists after other medications are discontinued and if she tolerates 50 mg well

4. Consider Low-Dose Antipsychotic ONLY if Severe

Only if agitation remains severe, dangerous, or causes significant distress after:

• Completing the taper of Celexa/Wellbutrin (allow 2-4 weeks to see baseline behavior)
• Implementing nonpharmacologic interventions
• Optimizing trazodone

Then consider:

• Risperidone 0.25-0.5 mg daily or quetiapine 12.5-25 mg daily 2
• Must discuss risks (increased mortality, stroke, falls) with decision-maker 2
• Reassess after 4 weeks; discontinue if no benefit 2

Critical Pitfalls to Avoid

⚠️ Do not restart medications she's been refusing—you'll perpetuate the withdrawal cycle

⚠️ Do not add new antidepressants—she needs simplification, not substitution

⚠️ Do not use benzodiazepines—they worsen cognition, increase falls, and cause dependence 3

⚠️ Do not use "as-needed" antipsychotics reactively—if antipsychotics are needed, use scheduled dosing 7

Address the Medication Refusal Pattern

Her refusal pattern suggests:

• Possible medication-related side effects (sedation, confusion, nausea from SSRIs)
• Lack of insight into need for medications (expected with advanced dementia) 8
• Timing issues—moving medications to bedtime may have increased confusion about why she's taking them

Solutions:

• Simplify to ONE medication (trazodone) at bedtime
• Use liquid formulations if available to ease administration
• Administer with preferred food/beverage
• Train staff in gentle persuasion techniques rather than confrontation 8

Bottom Line

Stop the Celexa and Wellbutrin through a proper taper, continue trazodone alone, and focus on behavioral interventions. The current regimen with 50% adherence is causing more harm than good through repeated discontinuation effects. A single well-tolerated medication (trazodone) that she takes most of the time is vastly superior to three medications she refuses half the time 3, 8, 6.
