Why do so many customers purchase Levocetirizine HCL
Levocetirizine dihydrochloride, the active component of XYZAL tablets and oral solution, is an orally active H1-receptor antagonist. The chemical name is (R)-[2-[4-[(4-chlorophenyl) phenylmethyl]-1-piperazinyl] ethoxy] acetic aciddihydrochloride. Levocetirizine dihydrochloride is the R enantiomer of cetirizine hydrochloride, a racemic compound with antihistaminic properties.
Levocetirizine hydrochloride is a medication prescribed to treat symptoms of seasonal allergies and hives. These symptoms can include sneezing, a runny nose, and watering eyes, as well as itching and rashes. This antihistamine can help alleviate allergy symptoms by inhibiting the actions of the chemical histamine in the body.
