Management of Long Haul COVID Symptoms
The management of long COVID requires a systematic, symptom-based approach focusing on ruling out other conditions first, followed by targeted interventions for specific persistent symptoms to improve morbidity, mortality, and quality of life. 1
Definition and Diagnosis
Long COVID (post-COVID-19 syndrome) is defined as:
- Symptoms persisting or relapsing for more than 12 weeks after acute COVID-19 infection
- Cannot be explained by an alternative diagnosis
- May affect patients regardless of initial disease severity 1
Diagnostic Approach
- Rule out other conditions first - Long COVID is a diagnosis of exclusion 1
- Confirm COVID-19 association - Document prior infection (though a positive test is not required) 1
- Assess symptom duration - Symptoms lasting >12 weeks qualify as long COVID 1
Common Symptoms and Assessment
The most prevalent symptoms include:
- Fatigue (31-58%)
- Dyspnea (24-40%)
- Cognitive impairment/"brain fog" (12-35%)
- Sleep disturbances (11-44%)
- Musculoskeletal pain (9-19%)
- Anosmia/dysgeusia (10-22%)
- Cough (7-29%)
- Chest pain (6-17%) 1
Initial Assessment
- Blood tests: Complete blood count, kidney and liver function, C-reactive protein, ferritin, B-type natriuretic peptide, and thyroid function 1
- Chest imaging: For patients with respiratory symptoms 1
- Functional testing: Exercise capacity tests (e.g., 1-minute sit-to-stand test) 1
- Autonomic testing: For postural symptoms, perform lying and standing blood pressure/heart rate recordings (3-minute active stand test) 1
Management Approach by Symptom
1. Fatigue Management
- Energy conservation strategies - Pacing activities and setting realistic goals 1
- Avoid post-exertional malaise - Carefully tailor physical activity to current tolerance 2
- Gradual return to activities - Phased approach to work or education 1
2. Respiratory Symptoms
- Breathing techniques:
- Pursed-lip breathing: Inhale through nose for several seconds, exhale slowly through pursed lips for 4-6 seconds
- Upright sitting to increase ventilation
- Leaning forward with arms bracing a chair to improve ventilatory capacity 1
- Respiratory rehabilitation - Consider referral to pulmonary rehabilitation 1
- For distressing cough: Consider codeine linctus, codeine phosphate tablets, or morphine sulfate oral solution 1
3. Cognitive Symptoms ("Brain Fog")
- Cognitive rehabilitation - Memory aids and cognitive exercises 1
- Structured daily routines - Maintain consistent schedules 2
- Avoid cognitive overexertion - Similar to physical pacing 2
4. Vertigo/Dizziness
- Vestibular rehabilitation therapy combined with symptomatic treatment using meclizine (25-100 mg daily in divided doses) 3
- For persistent vertigo: Consider short course of oral corticosteroids if vestibular neuritis is suspected 3
5. Fever Management
- Hydration - Regular fluid intake (no more than 2 liters per day)
- Antipyretics - Paracetamol preferred over NSAIDs for symptom relief 1
6. Psychological Support
- Validate patient experiences - Many patients report having symptoms dismissed 2
- Address anxiety and depression - These can worsen physical symptoms 1
- Social support - Connect with patient organizations and online support groups 1
Special Considerations
Risk Factors for Long COVID
- Female sex - Approximately two-fold increased risk
- Severe acute COVID-19 - Strongest association with fatigue
- Multiple early symptoms (>5) during acute infection 1
Return to Work/Activities
- Phased return - Gradual reintroduction to work or education
- Workplace accommodations - May be necessary as symptoms can fluctuate 2
- Disability considerations - Long COVID is recognized as a potential disability under the Americans with Disabilities Act 2
Red Flags Requiring Urgent Referral
- Severe hypoxemia or oxygen desaturation on exercise
- Signs of severe lung disease
- Cardiac chest pain
- Multisystem inflammatory syndrome 1
Pitfalls to Avoid
Overexertion - Pushing too hard can trigger symptom relapse; 85.9% of patients experience relapses triggered by physical or mental activity 4
Dismissing symptoms - Long COVID is a real condition with multisystem involvement; validate patient experiences 2
Missing alternative diagnoses - Always rule out other serious conditions that may mimic long COVID 1
One-size-fits-all approach - Symptoms vary widely between patients and require tailored management 1
Ignoring autonomic dysfunction - Postural symptoms are common and may require specific testing and management 1
By following this systematic approach to long COVID management, clinicians can help improve outcomes and quality of life for patients experiencing persistent symptoms after COVID-19 infection.
