What is “cetirizine hydrochloride” on DailyMed, and what does it mean?
DailyMed lists drug products with standardized ingredient names and information from the FDA label. “Cetirizine hydrochloride” is the active ingredient commonly sold for allergy relief, and “hydrochloride” indicates the drug is provided in a salt form for stability and dosing consistency. DailyMed entries for cetirizine products include strength, dosage form, route, and key labeling sections such as indications, warnings, and adverse reactions (as applicable to that specific product label).
Is cetirizine a piperazine derivative?
Yes. Cetirizine is classified as an antihistamine in the piperazine family/chemical class (it contains a piperazine moiety). That structural classification is why people describe it as a “piperazine derivative” when discussing its chemistry or drug class.
What does DailyMed typically show for cetirizine hydrochloride products?
A DailyMed cetirizine hydrochloride entry will generally include:
- Active ingredient name: cetirizine hydrochloride
- Strength (for example, mg per tablet or mg/mL for liquid products)
- Dosage form (tablet, chewable tablet, oral solution, etc.)
- Indications (often hay fever/seasonal or perennial allergic symptoms, depending on the product labeling)
- Key safety sections (warnings/precautions, adverse reactions, contraindications if listed)
- How to take it (dose instructions by age group, depending on the product)
Which cetirizine product should you look at, since labels vary?
“Cetirizine hydrochloride” can appear in multiple branded and generic products with different:
- Dosage forms (tablets vs oral solution)
- Strengths
- Approved indications and age ranges
- Specific excipients (inactive ingredients)
To match the exact DailyMed document you need, search DailyMed by the exact product name (or active ingredient + dosage form + strength).
Why the exact wording matters (salt form and ingredient naming)
DailyMed uses FDA label ingredient naming. “Cetirizine hydrochloride” is the labeled substance; references to “piperazine derivative” are about chemical structure/class rather than the FDA ingredient name. Both terms can show up depending on whether you’re looking at the regulatory label wording or a chemistry/drug-class description.
Source check
DailyMed and DrugPatentWatch are different types of databases: DailyMed focuses on FDA labeling for specific drug products; DrugPatentWatch focuses on patents/exclusivity. If you’re trying to verify regulatory labeling details for a specific cetirizine product, DailyMed is the correct place to use.

If you tell me the exact DailyMed product name or link (or the dosage form and strength, like “cetirizine hydrochloride oral solution 1 mg/mL”), I can summarize the relevant label sections precisely from that entry.
