What is the recommended dose of fluticasone (nasal corticosteroid) nasal spray for a patient with allergic rhinitis?

Fluticasone Nasal Spray Dosing for Allergic Rhinitis

For adults and adolescents ≥12 years with allergic rhinitis, start with 2 sprays per nostril once daily (200 mcg total dose), and for children ages 4-11 years, use 1 spray per nostril once daily (100 mcg total dose). 1, 2

Age-Specific Dosing Algorithm

Adults and Adolescents (≥12 years)

• Initial dose: 2 sprays (50 mcg each) per nostril once daily = 200 mcg total daily dose 1, 2
• Alternative regimen: 100 mcg twice daily (1 spray per nostril at 8 AM and 8 PM) is equally effective 2, 3
• Maintenance dose: After 4-7 days of symptom control, reduce to 1 spray per nostril once daily (100 mcg total) 2
• Maximum dose: Do not exceed 2 sprays per nostril daily (200 mcg total) 2

Children (4-11 years)

• Initial dose: 1 spray per nostril once daily = 100 mcg total daily dose 1, 2, 4
• If inadequate response: May increase to 2 sprays per nostril once daily (200 mcg total) 2
• Once controlled: Decrease back to 1 spray per nostril daily 2
• Maximum dose: Do not exceed 2 sprays per nostril daily (200 mcg total) 2
• Important: Studies show 100 mcg once daily is as effective as 200 mcg once daily in children, making the lower dose preferable 4

Young Children (2-3 years)

• Fluticasone propionate is NOT FDA-approved for ages 2-3 years 1
• Alternative: Fluticasone furoate (Veramyst) is approved for ages ≥2 years at 1-2 sprays per nostril daily 1, 5
• Other options: Mometasone furoate (approved for ages ≥2 years at 1 spray per nostril daily) or triamcinolone acetonide (approved for ages ≥2 years) 6

Timing and Onset Expectations

• Symptom relief begins: Within 12 hours of the first dose 6, 7, 2
• Some patients experience benefit: As early as 3-4 hours 6
• Maximum efficacy: Requires days to weeks of regular daily use 6, 7, 2
• Critical counseling point: Patients must continue therapy for at least 2 weeks to properly assess benefit, as full effect is not immediate 6

Administration Technique to Maximize Efficacy and Minimize Side Effects

Proper technique reduces epistaxis risk by 4-fold: 6, 7

• Use contralateral hand technique: Hold spray in opposite hand relative to the nostril being treated (right hand for left nostril, left hand for right nostril) 6
• Direct spray away from nasal septum to minimize bleeding and septal perforation risk 6, 7
• Prime the bottle before first use 6
• Shake bottle prior to each use 6
• Have patient blow nose before administration 6
• Keep head upright during administration 6
• Patient breathes in gently during spraying 6
• Do NOT close opposite nostril during administration 6
• If using nasal saline irrigations: Perform them BEFORE the steroid spray to avoid rinsing out medication 6

Special Dosing Considerations

Severe Nasal Congestion

• Higher initial dosing (2 sprays per nostril twice daily = 400 mcg/day) may be beneficial for severe congestion unresponsive to standard dosing 6
• Reduce to maintenance dosing once symptoms are controlled 6
• Consider short-term topical decongestant (maximum 3-5 days) while starting the steroid to open nasal passages 6

As-Needed Use (Seasonal Allergic Rhinitis Only, ≥12 years)

• Some patients with seasonal allergic rhinitis may use 200 mcg once daily on an as-needed basis (only on days when symptoms require control) 2
• However, scheduled regular daily use provides superior symptom control compared to as-needed use 2
• As-needed use has NOT been studied in children <12 years or in perennial allergic rhinitis 2

Common Side Effects and Safety Profile

Local Side Effects

• Epistaxis (nasal bleeding): Most common adverse event, occurring in 4-8% short-term and up to 20% with year-long use, typically presenting as blood-tinged secretions 6
• Nasal irritation and burning: Common, particularly with propylene glycol-containing formulations 6
• Headache: Reported commonly 6, 1
• Pharyngitis (throat irritation): Occurs in some patients 6, 1
• Nasal septal perforation: Rare but serious complication with long-term use 6

Systemic Safety (Reassurance for Long-Term Use)

• No hypothalamic-pituitary-adrenal axis suppression at recommended doses in children or adults 6, 4, 8
• No effect on growth in children at recommended doses 6, 4
• No ocular effects (cataracts or glaucoma) with long-term use 6
• No bone density effects at standard intranasal doses 6
• Minimal systemic absorption: Swallowed portion is not absorbed from gut; only nasally absorbed portion has systemic availability 8

Long-Term Use and Monitoring

• Intranasal corticosteroids are safe for indefinite long-term use when clinically indicated 6
• Minimum treatment duration: 8-12 weeks to properly assess therapeutic benefit 6
• Periodic nasal septum examination (every 6-12 months) to detect mucosal erosions that may precede septal perforation 6
• For perennial allergic rhinitis: Daily year-round therapy is appropriate due to unavoidable ongoing allergen exposure 6
• No evidence of nasal mucosal atrophy even after 1-5 years of continuous use 6

Important Contraindications and Cautions

• Contraindicated: In patients with hypersensitivity to fluticasone or any component of the formulation 6, 1
• If constipation develops: Look for alternative causes (e.g., oral antihistamines with anticholinergic effects), as fluticasone nasal spray does NOT cause constipation 6

When Initial Therapy Fails

• After 2 weeks of fluticasone alone: If inadequate response, add intranasal antihistamine (azelastine) for >40% greater symptom reduction 6, 7
• After 3 months without improvement: Consider short course of oral corticosteroids or proceed to CT imaging and surgical evaluation 6
• Avoid: Leukotriene receptor antagonists as primary therapy—they are significantly less effective than intranasal corticosteroids 6
