Get the latest Cetirizine shortage update for 2026. Learn about current supply status, why stock-outs happen, and what patients can do right now.
As of March 2026, Cetirizine is not listed on the FDA's official drug shortage database. This means there is no recognized nationwide shortage of oral Cetirizine products — including brand-name Zyrtec and generic equivalents.
However, that doesn't mean finding Cetirizine on pharmacy shelves is always easy. Many patients across the country have reported intermittent difficulty locating their preferred Cetirizine product, especially during peak allergy season. Here's what you need to know.
Even without a formal shortage, several factors can make Cetirizine hard to find at your local pharmacy:
Cetirizine is one of the top-selling OTC allergy medications in the U.S. When pollen counts spike in spring (March-June) and ragweed season hits in fall (August-October), demand can outpace what individual stores have stocked. Popular store-brand generics — which are priced lower and preferred by budget-conscious shoppers — tend to sell out first.
While multiple manufacturers produce generic Cetirizine (which is good for overall supply), individual supply chains can experience disruptions from:
Pharmacies and retailers use automated systems to reorder products based on historical sales data. If a particular store doesn't typically sell large quantities of Cetirizine, it may not order enough to handle a sudden surge — leading to temporary empty shelves even when the product is widely available elsewhere.
There's an important difference between a drug shortage and a local stock-out:
What most Cetirizine users are experiencing in 2026 are stock-outs, not a shortage. The product exists — it's just not always on your usual shelf at the exact time you need it.
If you're having trouble finding Cetirizine, here are actionable steps:
Use MedFinder to see which pharmacies near you currently have Cetirizine in stock. This saves you from making multiple trips or phone calls.
If your usual pharmacy is out, try other retailers — grocery stores, dollar stores, and warehouse clubs all carry Cetirizine. Don't forget about different formulations: liquid, chewable tablets, and orally disintegrating tablets may be available when standard tablets are not.

When you do find Cetirizine, consider buying a larger supply. Costco's Kirkland Aller-Tec offers 365 tablets for around $15-$18 — a full year's supply for less than the cost of one month of brand-name Zyrtec. Amazon and Walmart also sell bulk packs at competitive prices.
If you can't find Cetirizine at all, other second-generation antihistamines can provide similar relief:

While most people buy Cetirizine over the counter, some patients take it by prescription — either because their insurance covers it that way, because they need a higher dose, or because they use a prescription-only formulation like Zerviate (eye drops) or Quzyttir (IV).
If you have a prescription and your pharmacy can't fill it, ask your pharmacist to:
Zyrtec-D combines Cetirizine with pseudoephedrine (a decongestant). This product is kept behind the pharmacy counter (not on the open shelf) due to pseudoephedrine regulations. If you're looking for Zyrtec-D specifically, you'll need to ask at the pharmacy counter and show ID.
Zyrtec-D may have different availability patterns than regular Cetirizine because of the pseudoephedrine component, which has its own supply and regulatory considerations.
