What Is The Difference Between Zyrtec And Xyzal
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.

Not much: Zyrtec is a mixture of two mirror image drugs, levo and dextrocetirizine. Xyzal is a pure levocetirizine. Only the levo form is an active antihistamine. The dextro form is inactive but has no known side effects. The difference is cost, insurance coverage, and patient prejudice or preference. ...Read more
Close: Xyzal (levocetirizine) (levo-cetirizine) is the r-isomer, of zyrtec (cetirizine). Medications are usually a combination of r + s (called racemic). Typically only the r side contributes to the clinically meaningful action of the drug. So, the companies have been able to separate the active r side from the inactive s- side. This means it may be as or more effective at half the dose. ...Read more

Is it OK to take 180 mg Allegra in AM and 10m Zyrtec AND Xyzal (levocetirizine) at dinner? Allergist said to take TWO Allegra, but I'm worried it's too much
Mixing antihistamine: Generally, it's best to follow one's doctor's instructions. If not wanting to take Allegra twice a day, and wanting to add a different antihistamine such as Zyrtec or Xyzal (levocetirizine), (levocetirizine) it is probably enough to take Zyrtec or Xyzal (levocetirizine) (one of them instead of both of them). Zyrtec and Xyzal (levocetirizine) are very similar. The makers of Xyzal (levocetirizine) say it is more effective than Zyrtec, but they are similar drugs. ...Read more
Allergic rhinitis and sinusitis. Went from loratadine claratin To Zyrtec To finally Xyzal (levocetirizine). The first 2 meds didn't help much. Is Xyzal (levocetirizine) more effective?
