The common claim vs. the evidence

What’s commonly claimed, and what the evidence supports

Store-brand roundups and Reddit threads generally credit Perrigo, the largest US maker of private-label OTC drugs, and note the pills work like Claritin. FDA drug records line up with that: the plain AllerClear loratadine 10 mg (NDC 63981-612) is marketed under ANDA 076301, whose Drugs@FDA applicant is Perrigo, and a 2021 FDA recall (D-0355-2022) shows Perrigo packaging Kirkland Signature antihistamines "For Costco Wholesale Corporation" at its Allegan, Michigan plant. Both are indirect signals: the ANDA applicant is not always the physical packer (the AllerClear-D pseudoephedrine combo, a different product, was recalled in 2021 as an Ohm Laboratories / Sun Pharmaceutical lot). The evidence therefore points to Perrigo without rising to a flat confirmation.

Tier 3 DailyMed (U.S. National Library of Medicine) KIRKLAND SIGNATURE ALLERCLEAR - loratadine tablet (DailyMed SPL) Published · accessed July 5, 2026

DailyMed's FDA-sourced label is titled "KIRKLAND SIGNATURE ALLERCLEAR- loratadine tablet", names Costco Wholesale Company as the labeler (establishment DUNS 103391843), lists NDC 63981-612, and in Marketing Information gives Marketing Category "Abbreviated New Drug Application" with Application Number ANDA076301. No establishment or registrant other than Costco appears on the SPL, so the registry-based link runs through the ANDA number rather than an on-label "manufactured by" line. This is the brand-to-ANDA anchor; the sibling record (openFDA Drugs@FDA) resolves ANDA076301 to Perrigo.

Tier 3 U.S. Food & Drug Administration (openFDA Drugs@FDA) Drugs@FDA record for ANDA 076301 (loratadine 10 mg), sponsor Perrigo Published · accessed July 5, 2026

FDA's Drugs@FDA database resolves ANDA076301 (the application under which Costco markets the plain AllerClear loratadine 10 mg, NDC 63981-612) to sponsor/applicant PERRIGO, product LORATADINE 10 MG. Perrigo is the largest US maker of private-label OTC drugs. Graded probable, not confirmed: the ANDA applicant is FDA's responsible party for the product but is not always the physical packer: the related AllerClear-D combo (a different product, NDC 63981-724) was recalled in 2021 as an Ohm Laboratories Inc. lot (recalled by Sun Pharmaceutical, D-0069-2022), showing Costco can source even the AllerClear family from more than one maker. Independent corroboration that Perrigo sits in Costco's antihistamine supply chain: FDA recall D-0355-2022 (Class II, 2021) describes "KIRKLAND ALLER-FEX, Fexofenadine Hydrochloride Tablets, 180 mg... Packaged by Perrigo 515 Eastern Ave., Allegan, MI 49010, For Costco Wholesale Corporation", a sibling antihistamine, not loratadine itself.

Frequently asked

Who makes Kirkland Signature AllerClear (loratadine) for Costco?

FDA drug records point to Perrigo. Costco markets the plain AllerClear loratadine 10 mg under ANDA 076301, and FDA's Drugs@FDA database lists Perrigo (the largest US private-label OTC drugmaker) as that application's holder; a separate 2021 FDA recall shows Perrigo packaging Kirkland Signature antihistamines for Costco. Because Costco distributes under its own label and the FDA applicant is not always the physical packer, this evidence points to Perrigo rather than proving it outright.

Is Kirkland AllerClear the same as Claritin?

They share the same active ingredient (loratadine 10 mg) and meet the same FDA generic standard, which is why AllerClear works like Claritin. But they are different products: Claritin is a Bayer brand, while AllerClear is Costco's store-brand loratadine, marketed under a Perrigo-held ANDA. Same drug, different maker and label.

Did the manufacturer of Kirkland AllerClear change?

For the plain loratadine 10 mg tablets, no manufacturer change is publicly documented; FDA records have tied them to Perrigo's ANDA 076301 since the 2010 launch. The related AllerClear-D pseudoephedrine combos are more tangled: FDA recalls and listings tie them to more than one maker (Perrigo on one D-24hr listing, NDC 63981-138; an Ohm Laboratories / Sun Pharmaceutical lot recalled in 2021 on another, NDC 63981-724), a reminder that Costco can source even one product line from multiple contract manufacturers.
