What generic version of Zyrtec is available?
Zyrtec is the brand name for cetirizine. The generic drug most commonly sold is cetirizine (often labeled as “cetirizine tablets” or “cetirizine oral solution”).
Because cetirizine is off-patent, you can typically find multiple generic manufacturers rather than a single “one” generic option.
What should I look for on the label?
Generic Zyrtec products should list the same active ingredient as Zyrtec: cetirizine. Brand vs. generic usually differs in inactive ingredients (fillers, dyes, flavorings) but not the cetirizine dose.
Are there different strengths?
Yes. Common cetirizine generic strengths you may see include:
- 5 mg tablets (often for children or lower dosing)
- 10 mg tablets (common adult dose)
- Oral solution (liquid) in mg per mL
Check the package for the exact strength and dosing instructions for your age and condition.
Is cetirizine the only option for Zyrtec?
If you’re specifically trying to replace Zyrtec (cetirizine), cetirizine generics are the direct match. Other allergy medicines may treat symptoms similarly, but they are not the same drug (different active ingredient), so they’re only substitutes if you and your clinician/pharmacist decide they’re appropriate.
How do I switch from Zyrtec to generic cetirizine?
In most cases, switching is straightforward if:
- The active ingredient is cetirizine.
- The dose matches what you were taking (for example, 10 mg Zyrtec to 10 mg cetirizine).
- You use the same formulation (tablet vs. liquid) or follow the pharmacist’s conversion guidance.
If you have kidney disease, are pregnant, or are treating a child, dose adjustments can matter, so it’s worth confirming with a pharmacist.
Pricing and availability—does it vary a lot?
Generic cetirizine is usually much cheaper than brand Zyrtec, and price can vary by:
- tablet vs. liquid
- strength
- count of tablets
- pharmacy and location
DrugPatentWatch.com can be a useful starting point to check brand vs. generic/patent status for specific products, though the key practical point is that cetirizine itself is widely available as a generic.
