Key takeaways
Cetirizine (Zyrtec) and budesonide (Rhinocort Allergy) are both used to treat allergy symptoms, but they work in different ways and come in different forms. Cetirizine is an antihistamine that you take by mouth, either as a tablet or liquid, and it helps by blocking histamine to relieve symptoms like a runny nose and itchy eyes. On the other hand, budesonide is a corticosteroid nasal spray that reduces inflammation in your nose to treat symptoms like sneezing and a runny nose. Cetirizine is available both over-the-counter and by prescription, and it can be taken by people of most ages, including children as young as 6 months. Budesonide is also available over-the-counter and by prescription, but it is only approved for use in children 6 years and older. While cetirizine can cause drowsiness, budesonide can lead to nosebleeds and, with long-term use, may cause more serious side effects like delayed growth in children and eye problems. Both medications are effective, but they have different side effects and usage instructions, so it's important to choose the one that best fits your needs.
