Not really: Both are antihistamines that work well. There may some subtle differences between the two but in general either one is a good choice.

Very similar: Zyrtec is the brand name for the molecule cetirizine, whereas xyzal is levocetirizine, the mirror image. Xyzal came to market when zyrtec was going generic and over-the-counter. There are subtle differences between the two, but they behave very similarly.

No, but rarely yes.: Zyrtec (cetirizine) is pretty well-tolerated and now is over the counter. You should check with your doctor if you have known liver disease or experience difficulty breathing, seizures, or low blood pressures.
