What to do if a patient experiences dizziness due to non-adherence to medication?

Management of Dizziness Due to Medication Non-Adherence

When a patient experiences dizziness from medication non-compliance, immediately restart the prescribed medication at the appropriate dose while simultaneously addressing the underlying barriers to adherence through a combination of patient education, regimen simplification, and structured follow-up. 1

Immediate Clinical Actions

Assess the Medication and Restart Appropriately

• Determine which medication was discontinued and whether abrupt cessation could cause withdrawal-related dizziness (beta-blockers, clonidine, digoxin, antiplatelets) 1
• Restart the medication promptly unless contraindications have developed during the non-adherence period 1
• For cardiovascular medications requiring monitoring (renin-angiotensin-aldosterone system inhibitors, digoxin, warfarin), check appropriate laboratory parameters before restarting 1

Distinguish True Medication Side Effects from Disease Symptoms

• Recognize that most dizziness in patients with chronic conditions is NOT attributable to medications - in heart failure trials, hypotension occurred only 0.3-5.6% more frequently with guideline-directed medical therapy versus placebo 1
• Dizziness may represent worsening of the underlying disease state rather than a medication effect 1
• Avoid reflexively discontinuing medications for borderline symptoms when patients are not severely symptomatic 1

Address Non-Adherence Barriers

Identify Root Causes

Non-adherence is multifactorial and requires systematic assessment 1:

• Lack of understanding about medication importance and disease consequences 1
• Complexity of regimen - polypharmacy significantly increases non-adherence 1
• Physical barriers - inability to properly instill drops, open bottles, or swallow pills 1
• Cognitive impairment or psychiatric conditions (depression, hostility toward authority, memory impairment) 1
• Financial constraints - medication costs and insurance coverage issues 1
• Side effect concerns - real or perceived adverse effects 1

Implement Multi-Component Adherence Strategies

Because no single strategy works for all patients, combine multiple interventions 1, 2:

• Simplify the regimen: Use once-daily formulations, fixed-dose combinations, or medications treating multiple conditions simultaneously 1
• Provide clear written and oral instructions about medication timing, dosing, and importance 1
• Link medication-taking to daily activities to create routine habits 1
• Use reminder systems: Day-marked blister packs, medication boxes, smartphone apps (Medisafe, Dosecast, MyMeds), or SMS reminders 1
• Enlist family and social support to assist with medication administration 2

Patient Education - Emphasize Positive Outcomes

• Focus education on expected benefits (improved survival, well-being) rather than negative consequences of non-adherence, which can increase anxiety and worsen compliance 1
• Explain that symptoms may represent disease progression rather than medication side effects 1
• Repeat education at 6-month intervals or less for long-term treatments 1
• Provide specific information about when dizziness is likely medication-related versus disease-related 1, 3

Structured Follow-Up and Monitoring

Establish Regular Reassessment

• Schedule frequent follow-up visits initially (every 2-4 weeks) to monitor adherence, symptom improvement, and medication tolerance 1
• Directly ask about adherence at each visit - simple questioning detects most problems 2
• Monitor for appointment non-attendance and treatment non-response as adherence indicators 2
• Review medication timing and link to activities of daily living 1

Consider Enhanced Monitoring Systems

• Utilize pharmacy databases where available to track prescription refills 1
• Involve pharmacists in adherence monitoring and counseling 1
• Implement nurse-coordinated care for complex patients 1
• Use electronic monitoring when suboptimal adherence is suspected 1

Medication-Specific Considerations

When Dizziness May Be Medication-Related

True medication-attributable dizziness is uncommon but can occur with 3:

• Antihypertensive medications (most common cardiovascular cause)
• Antianxiety drugs and tricyclic antidepressants
• Aminoglycoside antibiotics and antituberculous drugs
• Non-steroidal anti-inflammatory drugs

Plan for Medication Rechallenge

• If a medication was stopped due to suspected side effects, plan to re-attempt when the patient is more stable 1
• Most patients can successfully restart medications after addressing adherence barriers 1

Long-Term Management

For chronic conditions requiring long-term therapy, effective adherence interventions are labor-intensive but cost-effective 2, 4:

• Combinations of convenient care, reminders, self-monitoring, reinforcement, counseling, and additional supervision are most effective 4
• Even the best interventions achieve only modest improvements in adherence (typically 50% baseline adherence) 2, 4
• Continuous, not one-time, intervention is required for sustained adherence 2
