A 19-year-old woman with asthma who takes inhaled fluticasone (2 puffs nightly) has been coughing for one week; what medication should she take?

Add a Short-Acting Beta-Agonist (SABA) for Immediate Symptom Relief

She should immediately start using an inhaled short-acting beta-agonist (albuterol/salbutamol) as needed for her cough, and if symptoms persist beyond a few days or worsen, she needs to step up her controller therapy by adding a long-acting beta-agonist to her current inhaled corticosteroid.

Clinical Reasoning

This 19-year-old woman is currently on Step 2 therapy (low-dose inhaled corticosteroid alone - fluticasone 2 puffs nightly). Her one-week cough represents either:

1. Inadequate asthma control requiring treatment escalation
2. Post-infectious cough following a viral respiratory infection
3. Asthma exacerbation triggered by infection or other factors

Immediate Management

First-Line Treatment

• Prescribe a SABA (albuterol/salbutamol) inhaler for immediate symptom relief 1
  • Use 2 puffs every 4-6 hours as needed for cough/breathlessness
  • Up to 3 treatments at 20-minute intervals if severe symptoms 1

Critical monitoring point: If she requires SABA more than 2 days per week for symptom relief, this indicates inadequate asthma control and necessitates stepping up controller therapy 1

Step-Up Controller Therapy (If Symptoms Persist >3-5 Days)

Since she's already on low-dose ICS (Step 2) and has persistent symptoms, step up to Step 3 therapy 1:

Preferred Option

Add a long-acting beta-agonist to her current ICS:

• Switch to combination fluticasone/salmeterol 100/50 mcg (or equivalent) 1 inhalation twice daily 1
• This provides both improved bronchodilation and anti-inflammatory control

Alternative Option (if combination therapy unavailable or not tolerated)

• Increase to medium-dose ICS alone (fluticasone 250 mcg twice daily) 1
• OR add a leukotriene receptor antagonist (montelukast 10 mg once daily) to her current low-dose ICS 1, 2

Asthma-Related Cough Considerations

The evidence shows that asthma-induced cough may take up to 8 weeks to fully resolve even with appropriate treatment 2. Key points:

• Most patients show partial improvement within 1 week of starting ICS and beta-agonist therapy 2
• Complete resolution requires patience and adherence
• If no improvement after 1-2 weeks on stepped-up therapy, consider adding a leukotriene inhibitor before resorting to oral corticosteroids 2

When to Consider Oral Corticosteroids

Only if the cough is severe, significantly affecting quality of life, AND she has failed to respond to:

1. SABA therapy
2. Stepped-up ICS/LABA combination
3. Addition of leukotriene receptor antagonist

Then consider: Prednisone 40 mg daily for 5-10 days 2, 3

Post-Infectious Cough Alternative

If this follows a recent upper respiratory infection and other asthma triggers have been ruled out 4, 5:

• Inhaled ipratropium bromide may attenuate post-infectious cough 4, 5
• Consider this if SABA alone is insufficient but you want to avoid stepping up long-term controller therapy
• Post-infectious cough typically resolves within 3-8 weeks 4, 5

Critical Safety Points

• Never use LABA monotherapy - always combine with ICS 1
• Assess adherence to her current fluticasone regimen before assuming treatment failure
• Check inhaler technique - improper technique is a common cause of apparent treatment failure
• Rule out environmental triggers, upper airway cough syndrome (post-nasal drip), or GERD if symptoms persist despite appropriate escalation 2

Practical Algorithm

1. Day 1-3: Start SABA as needed + continue current ICS
2. Day 3-5: If using SABA >2x/day → Step up to ICS/LABA combination
3. Week 2: If inadequate response → Add leukotriene receptor antagonist
4. Week 3-4: If still inadequate → Consider short course oral corticosteroids
5. Week 8: If cough persists → Investigate alternative diagnoses (GERD, post-nasal drip, non-asthmatic eosinophilic bronchitis)
