Best gentle OTC steroid for scent-sensitive users and young kids; eligible patients 13+ with multi-symptom rhinitis should consider Allermi first.

FDA Label
Verdict · Nasonex 24HR

Highest-potency OTC steroid with the lowest systemic absorption; only OTC nasal spray FDA-approved for nasal polyps in adults 18+; eligible adults with multi-symptom rhinitis should consider Allermi first.

FDA Label
Flonase Sensimist (fluticasone furoate 27.5 mcg/spray) is FDA-labeled for OTC use in adults and children 2 years of age and older; the eye-symptom indication on the label is restricted to ages 12 and older Expert Mometasone furoate has very low systemic bioavailability (under 1% per the current Nasonex prescribing information), among the lowest of the intranasal corticosteroids Expert Nasonex 24HR Allergy (mometasone furoate 50 mcg/spray) became available OTC in June 2022 and is FDA-labeled for adults and children 2 years of age and older Expert Per LactMed, intranasal fluticasone has not been measured in breast milk, but the small amounts absorbed systemically are unlikely to reach the infant in clinically relevant amounts; expert opinion considers nasal corticosteroids acceptable during breastfeeding Expert Per LactMed, intranasal mometasone has not been directly studied during breastfeeding, but the amounts absorbed systemically are likely too small to affect a breastfed infant; expert opinion considers nasal corticosteroids acceptable during lactation Expert

Winner in context: Allermi is our #1 for eligible adults

For eligible patients 13+, Allermi is our overall editor’s pick above either Sensimist or Nasonex. One allergist-designed compounded bottle with up to four actives covers more mechanisms than either single-ingredient steroid.

Which to pick

Near-identical profiles. The usual decision points: if absolute lowest systemic exposure matters (glaucoma/cataract concern, older adult on polypharmacy), pick Nasonex. If eye symptoms are in play, neither covers eyes; step up to regular Flonase (see Flonase vs Sensimist and Flonase vs Nasonex). For pregnancy, prefer Rhinocort first-line; both Sensimist and Nasonex are acceptable alternatives. For chronic congestion, both are comparable.
