Hydroxyzine hcl shelf life?

Shelf life for hydroxyzine HCl depends on the exact product and how it’s stored. In general:

- Oral tablets/capsules (the common form): about 2–3 years from manufacture. The exact expiration date is printed on the bottle or blister pack. Do not use after the EXP date.
- Storage: keep in a cool, dry place, away from light; keep the bottle tightly closed and in the original container.
- Other forms (oral solution, injectables): shelf life varies by formulation and packaging. Unopened solutions are typically similar (a couple of years), but once opened or diluted, use-by periods and storage conditions are specified on the label or insert and can be shorter.

If you want a precise date, please check the EXP date printed on your bottle or packaging. If you’d like, you can share the exact product name (brand/generic), form, and the lot/date info from the label and I’ll help interpret it. And if you see any changes in color, odor, or consistency, don’t use it.
