Question: is cetirizine the same as phenylephrine?
Answer: Sudafed Pe (Phenylephrine) is a good medication for relieving stuffy nose. It doesn't work as well as pseudoephedrine (Sudafed), but it has fewer side effects. Zyrtec (cetirizine) works to treat sneezing and runny nose, and causes less sedation compared to Benadryl.
