Treatment of Acute Cold Symptoms
For patients with acute cold symptoms, symptomatic treatment with a first-generation antihistamine-decongestant combination (brompheniramine/pseudoephedrine) or an NSAID like naproxen is recommended; antibiotics should never be prescribed as they provide no benefit and cause harm. 1
Core Management Principles
What NOT to Do
- Never prescribe antibiotics for the common cold - they are ineffective, increase adverse effects, and do not prevent complications like sinusitis, asthma exacerbation, or otitis media 1
- Avoid newer non-sedating antihistamines (e.g., loratadine, cetirizine) as they are ineffective for cold symptoms 1
- Do not use central cough suppressants (codeine, dextromethorphan) for acute URI-related cough - they have limited efficacy 1
- Avoid zinc supplements, over-the-counter combination cold medications (except older antihistamine-decongestant combinations), vitamin C, and echinacea as evidence does not support their use 1
Recommended Symptomatic Treatments
For general cold symptoms:
- First-generation antihistamine-decongestant combination (brompheniramine with sustained-release pseudoephedrine) provides significant relief in 1 out of 4 patients 1
- Naproxen reduces cough, post-nasal drip, and throat clearing 1
- Combination products containing ibuprofen/pseudoephedrine are most effective when started within the first 2 days of symptom onset, using 2 tablets rather than 1 tablet at first dosing 2
For specific symptoms:
- Rhinorrhea: Inhaled ipratropium bromide 1
- Nasal congestion: Inhaled cromolyn sodium 1
- Cough: Antitussives and analgesics may offer relief, though evidence is limited for acute URI 1
Special Considerations for Patients with Underlying Conditions
Asthma Patients
- Beta-blockers are only relatively contraindicated in asthma (not absolute) - cardioselective agents (bisoprolol, metoprolol succinate, nebivolol) can be used with close monitoring for wheezing and lengthening of expiration 1
- Cold symptoms can trigger asthma exacerbations; monitor closely for worsening dyspnea 1
- If acute exacerbation develops, use high-dose short-acting beta-2 agonists (albuterol 4-12 puffs via MDI with spacer or salbutamol 5 mg nebulized) immediately 3
- Add ipratropium bromide 0.5 mg for moderate-to-severe exacerbations 3
COPD Patients
- Beta-blockers are NOT contraindicated in COPD - cardioselective agents are preferred 1
- For post-viral wheezing or acute exacerbation, start with short-acting β-agonist (salbutamol 2.5-5 mg or terbutaline 5-10 mg) via nebulizer 4
- If inadequate response, add ipratropium bromide 500 µg 4
- Drive nebulizers with compressed air, not oxygen, if PaCO₂ is elevated or respiratory acidosis is present 3
- If sputum becomes purulent, add empirical antibiotics (amoxicillin, tetracycline derivatives, or amoxicillin/clavulanic acid) for 7-14 days 1, 4
- In elderly COPD patients, β-agonists may precipitate angina - first treatment should always be supervised 4
Patient Counseling
Expected Duration and Follow-up
- Symptoms typically last up to 2 weeks 1
- Approximately 25% of patients continue to have cough, post-nasal drip, and throat clearing at day 14 1
- Advise patients to follow up if symptoms worsen or exceed 2 weeks 1
Red Flags Requiring Medical Evaluation
- Coughing up blood 1
- Breathlessness 1
- Prolonged fever with feeling unwell 1
- Symptoms persisting beyond 3 weeks 1
- Recent hospitalization 1
Prevention
- Handwashing is the most effective method to reduce transmission as direct hand contact is the most efficient route of viral spread 1
- Patients should use handkerchiefs and avoid infecting others 1
Common Pitfalls to Avoid
- Do not diagnose bacterial sinusitis during the first week of cold symptoms, even if sinus imaging shows abnormalities (87% of patients with colds have maxillary sinus abnormalities on CT that resolve without antibiotics) 1
- Do not prescribe antibiotics to prevent complications - they do not reduce the risk of sinusitis, asthma exacerbation, or otitis media 1
- Avoid prescribing broad-spectrum antibiotics when narrow-spectrum agents would suffice (if antibiotics are truly indicated for a secondary bacterial infection) 1
- Do not use albuterol for acute or chronic cough not due to asthma 1
