Key takeaways
Pseudoephedrine (Sudafed) and budesonide (Rhinocort Allergy) are both used to treat nasal issues, but they work in different ways and are used for different conditions. Pseudoephedrine is a decongestant that you take by mouth to relieve nasal and sinus congestion from allergies and the common cold. It works by narrowing blood vessels in your nose and sinuses. On the other hand, budesonide is a corticosteroid nasal spray that you use to treat nasal allergy symptoms like sneezing, runny nose, and itching. It reduces inflammation directly in your nose. Pseudoephedrine is available over-the-counter but is restricted and must be purchased at the pharmacy counter, while budesonide is available both over-the-counter and by prescription. Pseudoephedrine can cause side effects like anxiety and headaches, and it might keep you awake if taken too close to bedtime. Budesonide, however, can cause nosebleeds and may take up to two weeks to show full benefits. Additionally, long-term use of budesonide can lead to more serious side effects like fungal infections in the nose or throat and delayed growth in children.
