Patient Education for Steroid Inhaler Use in Asthma
Patients taking inhaled corticosteroids for asthma must be taught proper inhaler technique, understand the difference between "preventer" and "reliever" medications, and receive instruction on recognizing worsening asthma symptoms, particularly nocturnal symptoms. 1
Core Educational Components
Understanding Medication Purpose
- Teach patients that inhaled corticosteroids are "preventers" (anti-inflammatory medications) that must be used regularly, even when asymptomatic, while bronchodilators are "relievers" for acute symptoms. 1
- Explain that inhaled corticosteroids suppress airway inflammation, which is central to asthma pathophysiology, and are the cornerstone of asthma management. 2, 3
- Emphasize that these medications control symptoms, improve lung function, prevent exacerbations, and may reduce asthma mortality. 3
Proper Inhaler Technique Training
Effective inhaler technique requires demonstration, patient practice with feedback, and reinforcement at every subsequent visit—a single instruction session is insufficient. 4
The recommended training approach includes: 4
- Teach the steps and provide written instruction handouts
- Demonstrate step-by-step use of the inhaler
- Have the patient demonstrate back to you while referring to the handout initially
- Provide specific feedback on what was done correctly and what needs improvement
- Reassess technique at every healthcare encounter using the handout as a checklist
Using an inhaler is a skill that must be learned through coaching and experience, similar to riding a bicycle—never assume all patients can use an inhaler correctly. 1
Spacer Device Considerations
- Consider using spacer devices with inhaled steroids to increase effectiveness and potentially reduce the dose needed. 2
- For children, use metered-dose inhalers with large volume spacer devices. 1
Recognizing Worsening Asthma
Patients must understand the importance of nocturnal symptoms as a key indicator of worsening asthma control. 1
- Instruct patients to monitor symptoms, peak flow measurements, and medication usage. 1
- Teach recognition of signs that asthma is deteriorating, with particular emphasis on nighttime awakening. 1
Side Effects and Safety Information
Local Side Effects
Patients should be counseled about potential local side effects and given a balanced view of treatment risks versus benefits. 1
- Hoarseness and oral candidiasis (thrush) are more common with higher doses (800-1000 mcg/day). 5, 6
- Rare instances of wheezing, cataracts, glaucoma, and increased intraocular pressure have been reported. 7
- Local infections of the nose and pharynx with Candida can occur rarely and may require discontinuation. 7
Systemic Effects Reassurance
Reassure patients that at recommended doses, inhaled corticosteroids do not cause clinically important adverse effects on bone mineral density, cortisol production, or glucose metabolism that occur with oral steroids like prednisone. 1
- Low doses for mild persistent asthma have no adverse effects on bone mineral density or hypothalamic-pituitary-adrenal axis function. 1
- Systemic effects are minimal at recommended doses, though potential risk increases with larger doses. 7
Self-Management Planning
Written Action Plan Components
Patients should receive a written self-management plan that includes: 1
- Monitoring of symptoms, peak flow, and drug usage
- Prearranged actions to take based on specific thresholds
- When to increase inhaled steroid dose (commonly doubling at first sign of deterioration, though evidence is limited) 1
- When to self-administer oral corticosteroids (typically when peak flow falls below 60% of normal or previously agreed individual threshold) 1
- When to urgently seek medical attention (when treatment is not working) 1
Peak Flow Monitoring
- Train patients in proper use of peak flow meters where appropriate (most children over 5 years can use one). 1
- Establish individualized peak flow thresholds for action based on the patient's personal best or predicted values. 1
Medication Adherence Strategies
Regular Use Emphasis
Patients must understand that inhaled corticosteroids should be used at regular intervals for optimal effect, not just when symptomatic. 7
- Some improvement may occur within 12 hours to 2 days, but full benefit may require several days of treatment. 2, 7
- Patients should not increase the prescribed dosage on their own but should contact their physician if symptoms don't improve or worsen. 7
Addressing Common Barriers
- Address the common misconception that inhaled corticosteroids are not needed during asymptomatic periods. 1
- Discuss concerns about adverse effects openly, as patient worry about side effects is a major barrier to compliance. 1
- Provide education that asthma is a chronic inflammatory disease requiring ongoing anti-inflammatory treatment. 1
Special Precautions and Warnings
Exposure to Infections
Warn patients to avoid exposure to chickenpox or measles and to consult their physician immediately if exposed. 7
- Patients should be observed for signs of immunosuppression. 8
Drug Interactions
- Caution patients about coadministration with strong CYP3A4 inhibitors (ketoconazole, ritonavir) which can increase systemic exposure and corticosteroid side effects. 7, 8
Monitoring Requirements
- Patients using inhaled corticosteroids for several months or longer should be examined periodically for Candida infection or other adverse effects on nasal/oral mucosa. 7
- Monitor growth in pediatric patients routinely. 8
Follow-Up and Ongoing Education
Education and training are the responsibility of the physician but can be shared with specially trained nurses, pharmacists, or physiotherapists. 1
- Provide adequate opportunity for patients and families to express expectations and hear how those can be met. 1
- Review progress at prearranged visits, inquiring about symptom control, medication usage, and any difficulties. 1
- Consider step-down of inhaled steroid dose once asthma is well-controlled for 1-3 months. 2
