Key takeaways
Nasonex (mometasone) and Beconase AQ (beclomethasone) are both corticosteroid nasal sprays used to treat allergy symptoms, but they have some differences. Nasonex is available both over-the-counter (OTC) and by prescription, while Beconase AQ is only available by prescription. Nasonex can be used by children as young as 2 years old for OTC use, whereas Beconase AQ is approved for children 6 years and older. Nasonex is also used to treat nasal polyps, while Beconase AQ is used to prevent nasal polyps from regrowing after surgery. Both medications can cause side effects like nosebleeds, headaches, and sore throat. Additionally, both medications can take 1 to 2 weeks to show full effects.
