Is cetirizine available as a generic, and who makes it?
Yes. Cetirizine is widely available as an FDA-regulated generic medication in the U.S., sold by multiple manufacturers in tablet and liquid forms. Generic availability typically depends on the specific strength and dosage form (for example, tablets vs. oral solution).
How do generic cetirizine tablets or liquid compare with brand-name Zyrtec?
Generic cetirizine is required to have the same active ingredient (cetirizine) and the same route of administration as the brand. The main differences are usually non-active ingredients (such as fillers or flavorings in liquids) and the appearance of the product, while the intended allergy symptom relief should be the same when taken as directed.
What are common strengths and dosage forms for generic cetirizine?
Generic cetirizine is commonly sold as:
- Tablets (multiple strengths)
- Oral solution (liquid dosing)
- Chewable formulations (depending on the market and manufacturer)
Exact available strengths vary by manufacturer and pharmacy.
How do you switch from Zyrtec to generic cetirizine?
Switching is usually straightforward because the active ingredient is the same. If you’re switching due to cost or availability, matching:
- the same cetirizine strength
- the same dosing instructions from the label or prescriber
is the safest approach. If you have kidney problems, or you’re dosing a child, double-check the dosing guidance on the specific product label.
Does the generic version have the same safety and side effects?
Generic cetirizine is expected to have the same safety profile as brand-name cetirizine because it contains the same active ingredient. Common patient-reported side effects can include drowsiness or fatigue (less often with some second-generation antihistamines than older options), dry mouth, and headache. If you experience severe allergic symptoms, stop and seek care.
What if a pharmacy says “no generic” or “not in stock”?
Availability varies by dose form (tablets vs. liquid) and strength. A pharmacy may be able to:
- substitute a different manufacturer’s generic
- switch you to a different dosage form (tablet vs. liquid) if dosing can be matched
- order from another wholesaler
If you need the liquid for a child, try asking specifically for “cetirizine oral solution generic” rather than just “cetirizine.”
