Initial Treatment for Nasal Polyps
Intranasal corticosteroids are the first-line treatment for nasal polyps, used twice daily to reduce polyp size, decrease inflammation, and improve nasal congestion, rhinorrhea, and sense of smell. 1, 2
First-Line Medical Management
- Start with intranasal corticosteroids twice daily as the cornerstone of therapy, which significantly reduces polyp size and controls symptoms including nasal obstruction and loss of smell 2, 3
- Specific effective agents include:
- Twice-daily dosing is more effective than once-daily dosing for optimizing treatment effects 2
- Add nasal saline irrigation as adjunctive therapy to help clear mucus and improve medication delivery 2
- Patients typically start feeling relief within the first day, but full effectiveness requires several days of consistent use 5
- Intranasal corticosteroids do not cause rebound congestion and can be used for up to 6 months in adults (age 12+) or 2 months per year in children (age 4-11) 5
When Initial Treatment Fails
If symptoms remain severe or uncontrolled after 1-2 weeks of intranasal corticosteroids alone, add a short course of oral corticosteroids followed by maintenance intranasal therapy. 1, 2
- Oral prednisolone 25-60 mg daily for 7-21 days is effective for severe nasal polyposis 1, 2
- Common regimens include:
- Short courses of systemic corticosteroids significantly reduce total symptom scores and nasal polyp scores within 2-4 weeks 2
- After completing oral corticosteroids, maintenance with intranasal corticosteroids is essential to sustain beneficial effects and prevent recurrence 2, 3
Important Clinical Considerations
- Topical corticosteroids work best for small to medium-sized polyps (grades 1-2), while large polyps (grade 3) may require systemic corticosteroids or surgery first 6
- Intranasal corticosteroids primarily reduce polyp size and nasal congestion but have negligible effect on restoring sense of smell, whereas systemic steroids improve all symptoms including olfaction 7
- Direct nasal spray away from the nasal septum to minimize local side effects like irritation and bleeding 1
- Periodically examine the nasal septum for mucosal erosions, which may suggest increased risk for septal perforation 1
Common Pitfalls to Avoid
- Do not rely solely on short courses of systemic corticosteroids without maintenance intranasal therapy, as this leads to symptom recurrence 2
- Do not use nasal decongestants as monotherapy or for more than 3 days, as this can lead to rhinitis medicamentosa (rebound congestion) 1
- Do not use single-dose or recurrent parenteral corticosteroids, as these carry greater potential for long-term systemic side effects 1
- If symptoms do not improve after one week of intranasal corticosteroids, consider that the patient may have a sinus infection requiring additional treatment 5
Special Populations
- Children with nasal polyps should be evaluated for cystic fibrosis 8
- In children, use intranasal corticosteroids at the lowest effective dose and monitor growth 1
- Patients with aspirin-exacerbated respiratory disease (AERD) and nasal polyps may benefit from aspirin desensitization followed by long-term daily aspirin therapy to reduce symptoms and need for polypectomies 2
- Patients with comorbid asthma require careful monitoring of total corticosteroid intake from both intranasal and inhaled sources 3
Advanced Options for Refractory Cases
- For inadequate response to standard therapy, corticosteroid-eluting sinus implants placed in the ethmoid sinus can significantly reduce nasal obstruction and polyp grade (OR 0.34) 2
- Leukotriene modifiers (montelukast) may provide subjective improvement when added to intranasal corticosteroids, though evidence is mixed 1, 2
- Functional endoscopic sinus surgery (FESS) is reserved for cases when medical treatment fails to adequately control symptoms 2
- Post-operative maintenance with intranasal corticosteroids prevents polyp recurrence significantly better than placebo (RR 0.73) 2
