What is the best course of treatment for a patient with a history of asthma, currently experiencing cough, congestion, and runny nose, despite being on Symbicort (budesonide/formoterol) and ipratropium-bromide, for one week?

Management of Cough, Congestion, and Runny Nose in an Asthmatic Patient Not Responding to Current Therapy

This patient most likely has upper airway cough syndrome (UACS) complicating their asthma, and should be started immediately on a first-generation antihistamine-decongestant combination plus an intranasal corticosteroid spray while optimizing their asthma controller therapy. 1, 2

Immediate Assessment and Optimization

Before escalating therapy, verify that the patient is using their Symbicort correctly, as improper inhaler technique is a common cause of treatment failure that must be excluded first 2. Additionally, confirm that the inhaled corticosteroid itself is not paradoxically triggering cough from the aerosol constituents 2.

The one-week duration of symptoms with congestion and runny nose strongly suggests UACS (previously called postnasal drip syndrome), which is one of the three most common causes of chronic cough and should be addressed first in the systematic evaluation 1, 2.

Primary Treatment Approach

For Upper Airway Symptoms (UACS)

• Start a first-generation antihistamine-decongestant combination (such as chlorpheniramine with pseudoephedrine or phenylephrine) 1, 2
• Add intranasal corticosteroid spray to address the nasal inflammation 2
• The typical response timeline is noticeable improvement within days to 1-2 weeks, though complete resolution may take several weeks to a few months 1

For Persistent Asthma Component

Since the patient's asthma symptoms are not controlled on Symbicort alone:

• Continue Symbicort (budesonide/formoterol) as it provides both anti-inflammatory and bronchodilatory effects 3, 4, 5
• Consider stepping up the inhaled corticosteroid dose if cough persists after addressing UACS 1, 2
• Add a leukotriene receptor antagonist (montelukast or zafirlukast) if response remains incomplete after optimizing UACS treatment 1, 2

Role of Ipratropium Bromide

The ipratropium bromide the patient is currently taking has specific utility:

• For rhinorrhea specifically: Ipratropium bromide nasal spray 0.03% (42 mcg per nostril three times daily) is highly effective at reducing rhinorrhea in perennial rhinitis 6, 7
• Combined with nasal corticosteroid: The combination of ipratropium bromide nasal spray with beclomethasone nasal spray is more effective than either agent alone for treating rhinorrhea 6
• For asthma exacerbations: Nebulized ipratropium bromide 500 mcg should be added to beta-agonists only if the patient is not improving with initial treatment 1

If the patient is using ipratropium bromide as a nebulized bronchodilator rather than nasal spray, this suggests they may be treating this as an asthma exacerbation rather than recognizing the upper airway component.

Critical Timeline Considerations

Do not assume treatment failure prematurely. Complete resolution of cough may require up to 8 weeks of treatment with inhaled corticosteroids, even though partial improvement often occurs after 1 week 2. The American Thoracic Society specifically warns against abandoning therapy after only 1-2 weeks 2.

If Initial Treatment Fails

If symptoms persist despite optimized UACS treatment:

1. Add or increase intranasal corticosteroid, nasal anticholinergic, or nasal antihistamine if nasal symptoms continue 1
2. Obtain sinus imaging to evaluate for acute or chronic sinusitis if UACS symptoms persist 1
3. Assess airway inflammation through induced sputum or bronchoalveolar lavage to identify persistent eosinophilia that may require higher-dose corticosteroids 2
4. Consider central-acting antitussives only after other measures have been exhausted 2

Common Pitfalls to Avoid

• Do not diagnose "unexplained cough" until completing systematic evaluation of UACS, asthma, and GERD with adequate treatment trials of appropriate duration 2
• Do not use antibiotics unless bacterial infection is documented 1
• Do not add nebulized ipratropium to routine asthma management unless treating acute severe asthma that is not responding to beta-agonists alone 1
• Verify the patient is not experiencing steroid-induced cough from the inhaler itself before escalating corticosteroid doses 2
