Does Zyrtec contain wheat or gluten as an excipient?

We cross-check each Zyrtec product label against four data sources: DailyMed (FDA Structured Product Labels), the European Medicines Agency centrally-authorised medicines database, the Plogsted curated gluten-free drug list, and the 2024 Mangione et al. pediatric pharmacy NDC analysis. Inactive ingredients are scanned against a 146-entry red-flag dictionary covering wheat, barley, rye, malt, source-ambiguous starches, and FDA gluten-free attestation phrases. Of 12 product labels we cross-checked, 1 list a gluten-derived ingredient outright. Generics from different manufacturers can differ — check which manufacturer's version your pharmacy dispensed before assuming any fill is safe.

Can different manufacturers' generic versions of Zyrtec have different gluten status?

Yes. Generics in the United States must use the same active ingredient as the brand, but they are not required to use the same inactive ingredients. Two generics of Zyrtec from different manufacturers can use entirely different starch sources, binders, and fillers. A pharmacy may also switch which manufacturer it dispenses between fills without notifying you. Each manufacturer-specific entry below corresponds to a separately-filed product label.

Drug context

About Zyrtec

Zyrtec is a brand name for cetirizine — the brand-name antihistamine cetirizine. The active ingredient is the same across brand and generic versions, but inactive ingredients (excipients) can differ between manufacturers, which is the whole point of this page.

Why this matters

Different manufacturers, different ingredients

Generics of Zyrtec use the same active ingredient, but they aren't required to use the same inactive ingredients. Your pharmacy may switch which manufacturer they dispense between fills, sometimes without telling you. The list below shows each manufacturer's product label as a separate entry, because that's the granularity that actually matters when you're celiac.

Background

What “gluten in a medication” actually means

Gluten enters drugs through their excipients — the inactive ingredients used to bind, coat, fill, or stabilize the dose. The main concern is wheat starch as a filler. Source-ambiguous starches (plain “starch”, pregelatinized starch, sodium starch glycolate, modified starch) get flagged for verification because their botanical origin isn't always disclosed on the label.

The 2024 Mangione et al. pediatric NDC analysis (689 NDCs across the top 100 pediatric medications) found 1.5% contained gluten outright; another 25.7% couldn't be confirmed either way. Liquid and oral-suspension formulations carry disproportionate risk because wheat starch is a common thickener. Full methodology →

Important. This page is informational. Drug labels can change without notice; a manufacturer attestation is point-in-time, not a warranty. If you have celiac disease and your pharmacy switches manufacturers, re-screen the new label before taking the dispensed product. For a definitive answer, call the manufacturer's medical-information line with the NDC code from your prescription bottle.
