What is the treatment for a persistent cough and sore throat?

Treatment for Persistent Cough and Sore Throat

For a persistent cough with sore throat, start with honey and lemon, dextromethorphan-containing cough remedies, and acetaminophen or ibuprofen for pain relief, as most cases are viral in nature and do not require antibiotics. 1, 2

Initial Assessment and Management

Determine the Likely Cause

• Most short-term coughs with sore throat are due to viral infections 1
• Antibiotics are not helpful for viral infections, even if producing phlegm 1

First-Line Treatment Options

1. Home remedies:

   • Honey and lemon mixture (most effective natural remedy) 1
   • Stay hydrated
   • Rest appropriately

2. Over-the-counter medications:

   • Dextromethorphan (15-30 mg three times daily) for cough suppression 2, 3
   • Acetaminophen or ibuprofen for pain relief and fever 1, 4
   • Menthol lozenges or vapor for symptomatic relief 1, 2

3. Avoid smoking and secondhand smoke exposure as these worsen symptoms 1

For Persistent Post-Infectious Cough (3-8 weeks)

If cough persists beyond 3 weeks but less than 8 weeks after an initial respiratory infection:

Step 1: First-Line Therapy

• Inhaled ipratropium bromide: 2 puffs (36 mcg) four times daily 1, 2

Step 2: If Cough Persists After 3-5 Days

• Add inhaled corticosteroids to the treatment regimen 2

Step 3: For Severe Paroxysmal Cough

• Consider short course of oral prednisone 30-40 mg daily for 5-7 days 1, 2

Step 4: Additional Therapy if Needed

• Dextromethorphan (15-30 mg three times daily) 2, 3
• Central-acting antitussives like codeine only if other options fail 2

Warning Signs Requiring Medical Attention

Seek medical care immediately if:

• Coughing up blood 1
• Experiencing breathlessness 1
• Having prolonged fever and feeling unwell 1
• Having underlying medical conditions (COPD, heart disease, diabetes, asthma) 1
• Recently hospitalized 1
• Symptoms persist for more than three weeks 1

Important Considerations

Antibiotic Use

• Antibiotics have no role in post-infectious cough unless there is evidence of bacterial superinfection 1, 2
• Green or yellow sputum may suggest bacterial infection, warranting medical evaluation 5

Medication Effectiveness

• Evidence for OTC cough medications is limited, with mixed results in clinical trials 6
• Dextromethorphan has shown some effectiveness in adults but limited evidence in children 6, 7
• Ibuprofen (400 mg) has been shown to be more effective than acetaminophen (1000 mg) for sore throat pain relief 8

Common Pitfalls to Avoid

1. Using antibiotics unnecessarily for viral infections
2. Continuing ACE inhibitor medications in patients with persistent cough 1
3. Failing to consider alternative diagnoses if cough persists beyond 8 weeks 2
4. Overlooking GERD as a potential cause of persistent cough 1
5. Overreliance on opioid antitussives, which can lead to dependence 2

Remember that most coughs are self-limiting and will resolve with supportive care. If symptoms persist beyond 3 weeks or are accompanied by warning signs, medical evaluation is warranted.
