The common claim
What most answers say — and what the evidence supports
There is no single widely-repeated answer online for who makes Kirkland Signature Aller-Fex - search results are dominated by drug databases and retail listings, and store-brand roundups tend to credit Perrigo only in passing as the largest US private-label OTC maker. FDA records pin it down: Kirkland Aller-Fex (fexofenadine HCl 180 mg, NDC 63981-847) is marketed under ANDA 212971, held by L. Perrigo Company, and two FDA recalls of the product (initiated July 2021 and February 2023) name Perrigo as the packager - the 2021 notice adds "For Costco Wholesale Corporation" - and Perrigo as the recalling firm. Aller-Fex is manufactured by Perrigo, per those FDA recall and Drugs@FDA records; the recall notice for one earlier lot lists the tablets as "Made in the Czech Republic" and packaged by Perrigo in Allegan, Michigan; the notice does not name the Czech plant.
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 2
FDA recall D-0905-2023 (Class II, Terminated; recall initiated 2023-02-09). Recalling firm: L. Perrigo Company. Product description: "Allergy ALLER-FEX, Fexofenadine Hydrochloride Tablets, 180 mg, 180-count cartons, Packaged by: Perrigo, 515 Eastern Ave., Allegan, MI 49010 USA. NDC 63981-847-48" - the exact Kirkland Signature Aller-Fex NDC (labeler Costco Wholesale Company, 63981-847). Reason: "Failed Impurities/Degradation Specifications." A stability/impurity recall of this product issued by Perrigo as the responsible firm, with the label attributing packaging to Perrigo, directly identifies Perrigo as the maker of record for Costco's Aller-Fex.
Tier 2
FDA recall D-0355-2022 (Class II, Terminated; recall initiated 2021-07-27). Recalling firm: Perrigo Company PLC. Product description: "KIRKLAND ALLER-FEX, Fexofenadine Hydrochloride Tablets, 180 mg/Antihistamine, 24HR, 180 count bottle, Made in the Czech Republic, Packaged by Perrigo 515 Eastern Ave., Allegan, MI 49010, For Costco Wholesale Corporation ... NDC 63981-571-48." Names Perrigo as packager "For Costco Wholesale Corporation" on the prior Aller-Fex 180-count NDC (63981-571). The "Made in the Czech Republic" line shows Perrigo is the FDA-responsible packager and recalling firm while tablet production for that lot took place outside the US at a plant the notice does not name - i.e. Perrigo is the maker of record, not necessarily the tablet-pressing plant.
Tier 3
FDA's Drugs@FDA database resolves ANDA212971 - the application under which Costco markets Kirkland Signature Aller-Fex fexofenadine HCl 180 mg (NDC 63981-847) - to sponsor_name "L PERRIGO CO" (L. Perrigo Company); products FEXOFENADINE HYDROCHLORIDE 180 MG and 60 MG, marketing status Over-the-counter. The same ANDA underlies many retailers' store-brand fexofenadine (openFDA lists Costco, Kroger, Walgreens, CVS, Target, Meijer, HyVee and others as labelers), so Perrigo is the shared ANDA holder for the line. This NDC->ANDA->sponsor join is indirect on its own; it corroborates the recall notices, which name Perrigo directly for this product.
Tier 3
DailyMed's FDA-sourced Structured Product Label "KIRKLAND SIGNATURE ALLER FEX (fexofenadine hydrochloride) tablet, film coated [Costco Wholesale Company]" (setid 651d14d1-c5de-4cb9-9484-b05986e641ac, SPL v3) lists NDC 63981-847, names Costco Wholesale Company as the only labeler/registrant, and gives Marketing Category "Abbreviated New Drug Application," Application Number ANDA212971. No establishment other than Costco appears on the SPL, so the brand-to-maker link runs through the ANDA number (resolved to Perrigo in Drugs@FDA), not an on-label "manufactured by" line. This is the brand-to-ANDA anchor.
