Who makes Kirkland Signature Aller-Fex (Fexofenadine HCl 180 mg), 180 Tablets?
As of August 30, 2026, the manufacturer of Kirkland Signature Aller-Fex (Fexofenadine HCl 180 mg), 180 Tablets is Perrigo, per recall notice evidence.
The common claim
What’s commonly claimed, 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
Each source is graded on the six-tier evidence rubric, where tier 1 is strongest. Sources are archived, so a citation still works if the original page moves or goes behind a paywall.
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.
