Question: are phenylephrine and cetirizine the same?
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. Works well to also treat hives and itchy skin.
