What generic can replace Zyrtec?
Zyrtec is the brand name for cetirizine. Generic versions of Zyrtec are typically sold as cetirizine tablets or cetirizine liquid under their generic name.
Are generic cetirizine products the same as Zyrtec?
For most people, yes. Generic cetirizine is intended to contain the same active ingredient (cetirizine) as Zyrtec and to work the same way for allergy symptoms like sneezing, runny nose, and itching/hives, though inactive ingredients and tablet/liquid formulations can differ.
What do you look for on the label?
You’ll usually see one of these:
- Active ingredient: cetirizine (often written as cetirizine hydrochloride)
- Strength: the same strength you’re used to (commonly 10 mg for many adult products, or pediatric liquid/tablet strengths)
Does it matter if it says “cetirizine” instead of “cetirizine HCl”?
No. “Cetirizine” products will often list cetirizine hydrochloride. That is the common form used in most cetirizine allergy medicines.
Which Zyrtec type are you using (tablets vs children’s liquid vs 24-hour)?
Zyrtec comes in different formulations (for example, 24-hour versions and children’s liquid). Your best generic match is usually the one with the same formulation type and dosing schedule (e.g., extended-release/24-hour vs immediate-release), because that affects how often you dose.
How to confirm with a pharmacist
If you tell the pharmacist or check the product you have (adult vs children, tablets vs liquid, and the mg strength), they can match you to the correct generic equivalent.
