Not much additional. Since Claritin is probably our weakest antihistamine adding it to any other is of limited value. Depending upon reason for xyzal (levocetirizine) might consider other type of medication; topical intranasal corticosteroid for nasal symptoms or fexofenadine or ceterizine for hives.
No serious effects. Both Xyzal (levocetirizine) and Claritin are new generation antihistamines with good safety profiles. Taking 1 tab of Xyzal (levocetirizine) with 1 tab of Claritin would likely have no ill effect. If allergy symptoms are not controlled and that is why 2 antihistamines were taken, see an allergist for a better medication plan.
I took Xyzal (levocetirizine) 14 hours ago. It wasn't working so I took a Claritin D 12-hour. Is this dangerous?
No. But caution if you become drowsy, don't drive, and if you have high blood pressure and use claritin-d.
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?
Allergy treatment. Basically, claritin, loratidine, zyrtec, allegra and xyzal (levocetirizine) 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.
