Mometasone Nasal
Prescription ·Exploratory record · not publication-reviewed ·Updated July 13, 2026
An intranasal corticosteroid for the treatment of allergic rhinitis (seasonal and perennial) and nasal polyps. Mometasone furoate nasal spray has one of the lowest systemic bioavailabilities (<0.1%) among intranasal corticosteroids, making it particularly attractive when minimizing systemic steroid effects is important (e.g., in children). Approved for prophylactic use starting 2-4 weeks before anticipated allergy season. Also used for nasal polyps to reduce polyp size and improve congestion.

What the research says.
A quick, data-only summary. The full evidence, dosing, and sources are below.
An intranasal corticosteroid for the treatment of allergic rhinitis (seasonal and perennial) and nasal polyps. NutriStack rates the supporting evidence as strong. Common adult dosing is Adults and children >=12 years: 2 sprays (50 mcg each) per nostril once daily (total 200 mcg/day); children 2-11 years: 1 spray per nostril once daily (100 mcg/day); nasal polyps: 2 sprays per nostril BID (as prescribed by your physician), though a prescriber sets the actual dose. This profile indexes 10 sources.
The bottom line
Evidence rating strong. Most-documented uses: treats seasonal and perennial allergic rhinitis, prophylactic use before allergy season (start 2-4 weeks prior), treats nasal polyps (reduces polyp size). 10 sources indexed (2008–2025), with 0 interaction records on file.
How it works, mechanistically.
Core mechanism
Binds to the intracellular glucocorticoid receptor with high affinity (relative receptor affinity approximately 2200, among the highest of all corticosteroids). The activated receptor-steroid complex suppresses NF-kB and AP-1 transcription pathways, reducing production of pro-inflammatory cytokines, prostaglandins, leukotrienes, and adhesion molecules. This decreases inflammatory cell infiltration (eosinophils, mast cells, lymphocytes) in the nasal mucosa, reducing mucosal edema, vascular permeability, and mucus secretion.
Dosing & protocol.
Applied intranasally. Systemic bioavailability <0.1%, the lowest of all commercially available intranasal corticosteroids. Any swallowed drug undergoes extensive first-pass hepatic metabolism. Shake well before use. Prime before first use and after periods of non-use (>1 week).10
