Zyrtec vs. Nasonex

Head-to-head comparisons of medication uses, side effects, warnings, and more.

Key takeaways

Cetirizine (Zyrtec) and mometasone (Nasonex 24HR Allergy) are both used to treat allergy symptoms, but they work in different ways and are used differently. Cetirizine is an antihistamine that you take by mouth, and it helps relieve symptoms like runny nose and itchy eyes by blocking histamine. It's available in various forms, including tablets and liquids, and can be taken once a day. On the other hand, mometasone is a corticosteroid nasal spray that reduces inflammation in your nose. It can be used to prevent and treat allergy symptoms and is available both over-the-counter and by prescription. Mometasone is typically used once daily and can take 1 to 2 weeks to show full effects, while cetirizine starts working within 20 to 60 minutes. Cetirizine can cause drowsiness, whereas mometasone does not. Additionally, mometasone can cause side effects like headaches and nosebleeds, and it has specific warnings for long-term use, such as potential vision changes and slowed wound healing.
