Key takeaways
Nasonex (mometasone) and Advil Allergy and Congestion Relief (ibuprofen/phenylephrine/chlorpheniramine) are both used to treat allergy symptoms, but they work in different ways and are used for different purposes. Nasonex is a corticosteroid nasal spray that reduces inflammation in the nose and is available both over-the-counter and by prescription. It is used to prevent and treat seasonal allergies and nasal polyps. On the other hand, Advil Allergy and Congestion Relief is a combination of an antihistamine, an NSAID, and a decongestant, and is taken orally. It provides short-term relief for a variety of symptoms from allergies and the common cold, such as runny nose, sneezing, and sinus pressure. Nasonex is suitable for children as young as 2 years old (OTC version), while Advil Allergy and Congestion Relief is only for those 12 and older. Nasonex can take 1 to 2 weeks to show full effects, whereas Advil Allergy and Congestion Relief works more quickly but needs to be taken every 4 hours. Additionally, Nasonex does not cause drowsiness, while Advil Allergy and Congestion Relief can make you sleepy and dizzy.
