Zyrtec-D XR Shortage Update: What Patients Need to Know in 2026

If you've had trouble finding Zyrtec-D XR at your pharmacy recently, you're not imagining things. Patients across the country report sporadic stockouts at their local pharmacies, especially during peak allergy and cold season. Here's what's actually happening — and what you can do about it.

Is Zyrtec-D XR on the FDA Shortage List in 2026?

As of 2026, Zyrtec-D XR (cetirizine HCl 5 mg / pseudoephedrine HCl 120 mg extended-release tablets) is NOT listed on the FDA's official Drug Shortage Database. This means there is no declared national manufacturing or distribution shortage.

However, the absence of an official shortage doesn't mean you'll always find it at your first stop. Localized, temporary stockouts are common, driven by factors unique to this product.

Why Do Zyrtec-D XR Stockouts Happen?

Several factors make Zyrtec-D XR more susceptible to stockouts than typical OTC products:

Behind-the-counter storage requirements. Federal law (the Combat Methamphetamine Epidemic Act of 2005) mandates pseudoephedrine products be kept behind the pharmacy counter. Pharmacies stock less volume and reorder more conservatively.

No online sales allowed. Federal law prohibits direct-to-consumer online purchases of pseudoephedrine. This concentrates all buying into physical pharmacy locations, putting more pressure on each store's inventory.

Seasonal demand spikes. Demand surges during spring tree/grass pollen season (February–May) and fall ragweed season (August–October), as well as during peak cold and flu season (November–February).

Purchase limits. Federal limits on pseudoephedrine purchases (3.6 g/day, 9 g/30 days per person) mean a single busy day can deplete pharmacy stock quickly during a demand surge.

Historical Availability of Cetirizine/Pseudoephedrine

Zyrtec-D (cetirizine/pseudoephedrine) has been available in the U.S. since the mid-1990s and became OTC in 2002. Unlike some newer medications, its manufacturing is well-established and spread across multiple generic manufacturers. The cetirizine component is one of the most widely produced antihistamines globally.

Pseudoephedrine supply itself is generally stable in the U.S., as it is a well-established chemical manufactured by multiple suppliers. The availability challenges are primarily logistical — not manufacturing-related.

What Should Patients Do If They Can't Find It?

Call ahead: Contact the pharmacy counter directly to check stock before making a trip

Ask for the generic: Generic cetirizine/pseudoephedrine ER 5mg/120mg is bioequivalent to Zyrtec-D XR and often more widely available

Try multiple chains: CVS, Walgreens, Walmart, Rite Aid, and Costco may have different stock levels

Use medfinder: A paid service —

medfinder.com — calls pharmacies near you to check which ones have your medication in stock, so you don't have to

Consider alternatives: Claritin-D or Allegra-D are comparable products that may be available when Zyrtec-D XR is not

Can I Get Zyrtec-D XR on Prescription?

Yes. Your doctor can write a prescription for cetirizine/pseudoephedrine (or any equivalent), which allows your pharmacist to order it for you if not in stock. A prescription also signals your pharmacist to source the medication from their wholesaler, which can sometimes make it easier to obtain when OTC stock is depleted.
