How long does Cetirizine Hydrochloride stay in your body?

The elimination half-life of cetirizine hydrochloride is about 8.3 hours (mean in healthy adults) — the time it takes the body to clear about half of it. As a rule of thumb, a medicine is mostly gone after roughly 4 to 5 half-lives, though this varies from person to person with age and kidney or liver function. This is the parent drug's elimination half-life; cetirizine's only metabolite has negligible antihistaminic activity, so it does not prolong the effect. The half-life is shorter in young children (per the label, roughly 33-41% shorter in ages 2-5 and about 63% shorter in ages 6-23 months) and is expected to be longer in older adults and in people with kidney or liver impairment.

Frequently asked questions

What does Zyrtec treat?

Zyrtec (Cetirizine Hydrochloride) may be used to treat 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 Zyrtec work?

Zyrtec 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 Zyrtec 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.

Is there a coupon or discount for Zyrtec?
