Who makes Kirkland Signature AllerClear (Loratadine 10 mg), 365 Tablets?
As of July 5, 2026, evidence points to Perrigo as the manufacturer of Kirkland Signature AllerClear (Loratadine 10 mg), 365 Tablets, but no tier 1–3 source names the link directly.
The common claim
What most answers say — 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) - so the evidence points to Perrigo without rising to a flat confirmation.
Evidence & sources
Every source is graded on the six-tier rubric and archived, so the citation holds even if the original moves or paywalls. The tier badge grades the source; the status grades our confidence in the maker.
Tier 3
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 deterministic 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
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.
