Should an Elderly Patient with Falls Take Plavix (Clopidogrel)?

Yes, an elderly patient with a history of falls should generally continue taking Plavix (clopidogrel) if there is a clear cardiovascular indication, as the thromboembolic risk from discontinuation typically outweighs the bleeding risk from falls, but this requires comprehensive fall prevention interventions and medication review to minimize overall risk.

Understanding the Risk-Benefit Balance

The concern about antiplatelet agents like clopidogrel in patients with falls centers on intracranial hemorrhage risk. However, the evidence demonstrates that:

• The absolute risk of serious bleeding from falls is lower than commonly perceived and is generally outweighed by the reduction in cardiovascular events when there is a clear indication for antiplatelet therapy 1
• Antiplatelet agents like clopidogrel are identified as fall-risk-increasing drugs (FRIDs), but this classification relates to their potential to cause dizziness or orthostatic effects, not primarily to bleeding risk 2
• The decision should prioritize the cardiovascular indication - if clopidogrel is prescribed for acute coronary syndrome, recent stent placement, or secondary stroke prevention, the mortality benefit typically exceeds fall-related bleeding risk 3

Critical Assessment Required Before Continuing Clopidogrel

Verify the Cardiovascular Indication

• Confirm there is a valid, current indication for clopidogrel therapy (acute coronary syndrome, recent PCI with stent, ischemic stroke prevention) 3
• Reassess whether dual antiplatelet therapy is still necessary - if the patient is beyond the recommended duration post-stent or post-acute event, consider whether aspirin monotherapy might be sufficient 3

Comprehensive Fall Risk Assessment

The patient requires immediate multifactorial fall evaluation including:

• History of falls in the past year, feelings of unsteadiness, and recent fall events - positive responses mandate comprehensive assessment 4, 5
• Medication review focusing on polypharmacy (≥4 medications increases risk), psychotropic agents, cardiovascular drugs (especially calcium channel blockers, diuretics, beta-blockers), and vestibular suppressants 4, 6
• Gait and balance testing using Timed Up and Go test - completion time >10-12 seconds indicates high fall risk requiring intervention 5, 7
• Orthostatic blood pressure measurements to identify postural hypotension 8, 6
• Cognitive screening for executive function deficits and dementia, which significantly increase fall risk 4
• Vision assessment as visual impairment is a modifiable risk factor 5

Mandatory Fall Prevention Interventions

If continuing clopidogrel, you must implement aggressive fall prevention strategies:

Exercise and Physical Therapy

• Prescribe supervised balance training exercises 3 or more days per week with strength training twice weekly - this reduces fall rates by 23% 4, 7
• Refer to physical therapy for gait training and assessment for appropriate assistive devices 5, 8
• Consider tai chi programs as a balance-focused intervention 4

Medication Optimization

• Conduct comprehensive medication review with focus on deprescribing or dose-reducing psychotropic medications (benzodiazepines, antidepressants, antipsychotics), which have the strongest association with falls 4
• Review cardiovascular medications - calcium channel blockers (OR 2.05), beta-blockers (OR 1.88), and spironolactone (OR 4.10) significantly increase fall risk 6, 9
• Reduce total medication count if ≥4 medications as polypharmacy is an independent fall risk factor 7, 2

Environmental Modifications

• Arrange occupational therapy home safety assessment with direct intervention 5
• Remove loose rugs and floor clutter, ensure adequate lighting, install grab bars in bathroom 5
• Recommend properly fitting non-skid footwear 5

When to Consider Discontinuing Clopidogrel

Deprescribing should be considered in specific circumstances:

• Severe frailty with limited life expectancy where cardiovascular benefit is unlikely to be realized 1
• Recurrent falls despite maximal fall prevention interventions combined with evidence of cerebral microbleeds on imaging suggesting high intracranial hemorrhage risk 1
• No clear ongoing cardiovascular indication - if prescribed inappropriately or beyond recommended duration 2
• Patient/family preference after shared decision-making discussing risks and benefits 1

Critical Monitoring and Follow-Up

• Reassess fall risk and gait stability at regular intervals using standardized instruments 7
• Monitor for recurrent falls as this patient population remains at high risk 5
• Ensure physical therapy and occupational therapy appointments are scheduled and attended 5
• Consider bone health evaluation with DEXA scan to assess fracture risk in high-risk patients 5, 7

Common Pitfalls to Avoid

• Do not automatically discontinue clopidogrel based solely on fall history without weighing the cardiovascular indication - the stroke or MI risk from stopping may exceed bleeding risk 1
• Do not prescribe assistive devices without proper training and fitting as improperly used walkers can themselves become fall hazards 5
• Do not focus solely on the antiplatelet agent while ignoring other modifiable fall risk factors like psychotropic medications, environmental hazards, and lack of exercise 4, 2
• Avoid off-label dose reduction of antiplatelet agents as this reduces efficacy without proportional reduction in bleeding risk 1
