Frequently asked questions

What does Xyzal Allergy 24hr treat?
Xyzal Allergy 24hr (Levocetirizine Dihydrochloride) may be used to treat seasonal allergic rhinitis, perennial allergic rhinitis, urticaria, based on NIH RxClass drug-classification data (conditions a drug may treat — not a verbatim copy of the FDA-approved label). This is general reference, not medical advice.
How does Xyzal Allergy 24hr work?
Xyzal Allergy 24hr is a histamine-1 receptor antagonist. H1 antihistamines work by blocking histamine, the chemical released during an allergic reaction, from attaching to H1 receptors. This prevents the sneezing, itching, runny nose, watery eyes, and hives that histamine would otherwise trigger.
How much does Xyzal Allergy 24hr cost?
Nobody can tell you what you will pay — your price is set by your insurer's formulary, your deductible and the pharmacy's markup, and none of those are published. What IS published is what the pharmacy paid to acquire it: about $0.06 per ml, per the CMS NADAC survey. Treat that as the floor, not the quote — ask the pharmacist for the cash price as well as your copay, because for cheap generics the cash price often wins.
