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. ...Read moreSee 2 more doctor answers
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

Hard to say: You are on two medications (Plaquinil and Gabapentin) which can be associated with side effects and thus the question whether is safe or not depends on the perspective related to risk/benefit ratio. However there is no evidence that vit A or even vit C supplements are beneficial and thus I would consider stopping these two. ...Read more
Allergic rhinitis and sinusitis. Went from loratadine claratin To Zyrtec To finally Xyzal. The first 2 meds didn't help much. Is Xyzal more effective?
Allergy treatment: Basically, claritin, loratidine, zyrtec, allegra and xyzal are all 2nd generation antihistamines. If your symptoms are not controlled on these, you may need to be given intranasal steroids like flonase, nasonex or other treatments like singular, and also trying regular nasal saline. If still no improvement, time to see the allergist. ...Read more
Can Flonase be used 2x a day once am & once pm for nasal drip/allergies? If so, for how long can i continue this? Also on Xyzal, Zyrtec, & Singulair.
See below.: Flonase is usually taken once per day, unless your doctor prescribing it has told you otherwise. Also, both Xyzal and Zyrtec are long-acting antihistamines, also usually taken only once per day. You should discuss all of your medications with your doctor and they can advise you of the best way to take your allergy medications. ...Read more
Close: Xyzal (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
I usually take 2 xyzal/day but can't get it refilled anymore. Also, my allergies have started breaking through on it. Should I take two zyrtec?
None really: Possibly less sedation, otherwise no advantages.Get a more detailed answer ›
Whichever works: for you would be the best to use, although it treats only one aspect of the disease, nasal itching and runny nose ,won't affect congestion, also during an allergy season you need to take it on regular, not on as needed basis, in the end if you are not controlled you need to see an allergist ...Read more
