What is the best treatment approach for a patient with worsening rhinorrhea and nasal congestion, with a history of allergy, clear lung sounds, and stable vital signs?

Treatment Approach for Allergic Rhinitis with Worsening Rhinorrhea and Nasal Congestion

Start with an intranasal corticosteroid as first-line monotherapy, as this is the most effective single agent for controlling all symptoms of allergic rhinitis, including both rhinorrhea and nasal congestion. 1

Initial Treatment Strategy

• Prescribe an intranasal corticosteroid (fluticasone, mometasone, budesonide, or triamcinolone) as daily maintenance therapy for this patient with moderate symptoms and clear allergic history 1, 2
• Intranasal corticosteroids are superior to oral antihistamines for nasal congestion and provide comprehensive symptom control 3
• Instruct the patient to direct the spray away from the nasal septum toward the lateral nasal wall to prevent mucosal irritation and potential septal perforation 1
• Use daily at regular intervals, not as-needed, for optimal efficacy 4

If Severe Congestion Prevents Medication Delivery

• Add topical oxymetazoline for a maximum of 3 days only if nasal congestion is so severe that the intranasal corticosteroid cannot reach the nasal mucosa effectively 1, 4
• This short-term decongestant use allows the corticosteroid to penetrate and begin working 4
• Critical pitfall to avoid: Never use topical decongestants beyond 3 days, as rhinitis medicamentosa (rebound congestion) will develop and worsen the underlying condition 1, 4

If Symptoms Persist After 2-4 Weeks

• Add an intranasal antihistamine (azelastine or olopatadine) to the intranasal corticosteroid regimen 1, 4
• This combination provides superior symptom reduction compared to either agent alone, with 37.9% improvement versus 29.1% for intranasal corticosteroid alone 4
• Intranasal antihistamines are effective for both allergic and nonallergic rhinitis and have clinically significant effects on nasal congestion 3, 5
• Warn patients that 12.8% may experience bitter taste and some may experience mild sedation 3

What NOT to Do

• Do not routinely add oral antihistamines to intranasal corticosteroids, as multiple high-quality trials show no additional benefit 1
• Do not add leukotriene receptor antagonists (montelukast) to intranasal corticosteroids, as they provide no additional benefit and are less effective than intranasal corticosteroids alone 1
• Avoid first-generation antihistamines due to significant sedation and performance impairment 3, 1
• Never use recurrent parenteral corticosteroids, as this is contraindicated due to long-term adverse effects 3

Adjunctive Measures

• Implement allergen avoidance strategies even during early treatment 1
• Add nasal saline irrigation as beneficial adjunctive therapy for chronic rhinorrhea symptoms 3, 1

When to Refer

• Refer to an allergist/immunologist if symptoms remain inadequately controlled after 2-4 weeks of optimal pharmacotherapy 1, 4
• Consider allergen immunotherapy for patients with inadequate response to medications, as this is the only treatment that modifies the natural history of allergic rhinitis and may prevent development of asthma and new allergen sensitizations 3, 1
