Key takeaways
Loratadine (Claritin) and pseudoephedrine (Sudafed) are both over-the-counter medications, but they serve different purposes and belong to different drug classes. Loratadine is an antihistamine used to relieve allergy symptoms like runny nose and itchy eyes. It is typically taken once daily and is less likely to cause drowsiness compared to other antihistamines. On the other hand, pseudoephedrine is a decongestant that helps relieve nasal and sinus congestion. It works by narrowing blood vessels in the nasal passages and is available in both short-acting and extended-release forms. While loratadine is generally safe for children as young as 2 years old, pseudoephedrine is not recommended for children under 4 years old. Additionally, pseudoephedrine can raise blood pressure and heart rate, making it unsuitable for people with certain health conditions. Loratadine is not likely to cause these cardiovascular side effects. Both medications should be used with caution to avoid accidental overdose, especially since they can be found in many combination products.
