How long does Hydroxyzine Hydrochloride stay in your body?

The elimination half-life of hydroxyzine hydrochloride is about 14 to 20 hours in healthy adults (two reported mean values: 20.0 ± 4.1 hours and 14.0 hours) — 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. It varies a lot by age — averaging about 29 hours in older adults and about 7 hours in children. Hydroxyzine is broken down into an active metabolite, cetirizine (itself an antihistamine), which is cleared by the kidneys and can build up when kidney function is impaired.

How much does Vistaril 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 $0.04 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 Vistaril?

pharmaranks is an independent ratings site, not a pharmacy — we don't issue coupons or sell Vistaril. To pay less, ask your prescriber or pharmacist whether a generic equivalent exists, check the manufacturer's copay/savings card and patient-assistance program, and compare a pharmacy discount card against your insurance copay. Prices vary by pharmacy, insurance, and location, so always confirm at the counter. This is general reference, not medical or financial advice.
