The common claim vs. the evidence
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 capsules work like Prevacid. FDA drug records and Costco's own listing both line up with that: the Kirkland Signature lansoprazole 15 mg delayed-release capsules (NDC 63981-582) are marketed under ANDA 202319, whose Drugs@FDA applicant is Perrigo, and Costco's own product listing for the 42-count three-pack independently carries "L Perrigo Company" in its manufacturer field. The two routes agree: Kirkland Signature lansoprazole is manufactured by Perrigo, per Costco's product-catalog manufacturer field (L. Perrigo Company) corroborated by FDA's Drugs@FDA record for ANDA 202319. The FDA route alone is indirect - the ANDA applicant is not always the physical packer, and the same application backs more than a dozen other store-brand lansoprazoles and, since 2023, Perrigo's own Prevacid 24HR - which is why the retailer's own field naming the same company is what closes the attribution. No FDA recall or news report names a different maker for the Kirkland listing.
The receipts
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 "KIRKLAND SIGNATURE LANSOPRAZOLE- lansoprazole capsule, delayed release" names Costco Wholesale Company as the labeler (DUNS 103391843), lists NDC 63981-582 (lansoprazole 15 mg delayed-release capsules, 42-count / 3-pack), and gives Marketing Category "Abbreviated New Drug Application" with Application Number ANDA202319. The Principal Display Panel reads "COMPARE TO PREVACID 24 HR." No establishment other than Costco appears on the SPL, so the maker is identified through the ANDA number rather than an on-label "manufactured by" line. This is the brand-to-ANDA anchor; the sibling source (openFDA Drugs@FDA) resolves ANDA202319 to Perrigo.
Tier 3
FDA's Drugs@FDA database resolves ANDA202319 - the application under which Costco markets Kirkland Signature Lansoprazole 15 mg delayed-release capsules (NDC 63981-582) - to sponsor/applicant PERRIGO R AND D (Perrigo), product LANSOPRAZOLE 15MG, marketing status Over-the-counter. Perrigo is the largest US maker of private-label OTC drugs. On its own this join would cap the grade at probable: the NDC-to-ANDA-to-sponsor join is indirect, and the ANDA applicant is FDA's responsible party for the product but is not always the physical packer. Costco's own catalog manufacturer field naming L. Perrigo Company for the same item (see the Costco Business Delivery source) is the independent corroboration that carries the record to confirmed (DECISIONS 2026-08-30). ANDA202319 is a shared private-label application - openFDA lists 16 brand names across roughly 20 product listings under it (Equate, Up & Up, Member's Mark, Berkley & Jensen, Good Sense, TopCare, Good Neighbor Pharmacy, Kirkland Signature - and Perrigo's own Prevacid 24HR), consistent with Perrigo running one OTC lansoprazole line across many store labels rather than a Kirkland-specific one.
Tier 3
The earlier Kirkland lansoprazole label, now delisted: DailyMed's SPL for NDC 63981-117 (packages -01 and -03; labeler Costco Wholesale Company, DUNS 103391843) gives Marketing Category ANDA with Application Number ANDA202319 - the same Perrigo application as the current NDC 63981-582 - with marketing dates 12/17/2013 to 11/01/2023 (SPL version 8, effective 2026-01-27, the delisting update). Its label text ends "For Questions or Comments About Lansoprazole Delayed-Release Capsules 15 mg Call 1-800-719-9260 Distributed By Perrigo® Allegan, MI 49010" - the only Kirkland lansoprazole label that prints Perrigo's name. "Distributed By" is distribution language rather than a packager or manufacturer statement, so it corroborates the ANDA route without lifting the grade on its own (the on-carton naming that promotes to confirmed under DECISIONS 2026-08-30 is "Packaged By"); the confirmed grade rests instead on Costco's own catalog manufacturer field agreeing with the ANDA route (see the Costco Business Delivery source). Not a history[] entry: same maker before and after the relisting. DailyMed's search hides delisted labels; the page itself still resolves, and openFDA's label endpoint still serves it.
Tier 4
Costco's Business Delivery storefront (costcobusinessdelivery.com) serves the same US catalog data as costco.com and, unlike costco.com, can be fetched and archived. Its page for this item - 'Kirkland Signature Lansoprazole Acid Reducer, 15mg, 3 pk, 42 Delayed-Release Capsules' (item 100243800) - embeds catalog JSON whose manufacturer field reads mfName: "L PERRIGO COMPANY", L. Perrigo Company being Perrigo's principal US operating company (Allegan, MI). Read on August 30, 2026 and verified present in the Wayback snapshot created the same day. An internal catalog field rather than an editorial statement, and such fields can name a supplier-of-record rather than the plant; here it independently corroborates the FDA route (NDC 63981-582 -> ANDA 202319 -> sponsor Perrigo R&D) - the retailer and the regulator naming the same company - which satisfies the mfName-plus-independent-naming rule for confirmed (DECISIONS 2026-08-30). The ANDA holder remains FDA's responsible party rather than a guaranteed physical packer; the retailer's own field agreeing with it is what closes the attribution. It also sits beside the earlier carton's "Distributed By Perrigo, Allegan, MI" line (the delisted NDC 63981-117 label), which was distribution language only.

Frequently asked
Who makes Kirkland Signature lansoprazole for Costco?
FDA drug records and Costco's own listing both point to Perrigo. Costco markets Kirkland Signature lansoprazole 15 mg delayed-release capsules (NDC 63981-582) under ANDA 202319, FDA's Drugs@FDA database lists Perrigo - the largest US private-label OTC drugmaker - as that application's holder, and Costco's product listing for the 42-count three-pack carries "L Perrigo Company" in its manufacturer field. Kirkland Signature lansoprazole is manufactured by Perrigo, per those two sources. Costco distributes under its own label and the FDA applicant is not always the physical packer, so it is the retailer's own field naming the same company that makes this a confirmed attribution rather than an inference from the FDA paperwork alone.
Is Kirkland lansoprazole the same as Prevacid 24HR?
They share the same active ingredient - lansoprazole 15 mg delayed-release - and meet the same FDA generic standard, which is why the Kirkland capsules work like Prevacid 24HR; Kirkland's own carton says "Compare to Prevacid 24HR." But they are different products with the same FDA paperwork behind them: Prevacid 24HR is the brand (Takeda owns the trademark; Perrigo bought the US OTC rights from GSK in 2019 and now lists Prevacid 24HR under the very same ANDA 202319, NDC 0113-6117), while Kirkland lansoprazole is Costco's store-brand capsule under that application. Same drug, same FDA application holder, different label and price.
Did the manufacturer of Kirkland lansoprazole change?
No manufacturer change is publicly documented. Costco's listing did change once - the earlier Kirkland Signature Lansoprazole (NDC 63981-117, marketed December 2013 to November 2023) was joined by NDC 63981-582 in November 2021 and then delisted - but both sit under Perrigo's ANDA 202319, and the earlier carton read "Distributed By Perrigo, Allegan, MI," so the switch was a relisting, not a new maker. FDA records tie the current Kirkland listing (NDC 63981-582) to ANDA 202319, whose Drugs@FDA holder is Perrigo, Costco's own product listing for it names L. Perrigo Company in its manufacturer field, and no FDA recall or news report names a different maker for it. One caution: ANDA 202319 is a shared application covering more than a dozen store brands, so "who makes it" could shift at the pack or lot level if Costco ever re-sourced - the kind of change this record's history log exists to catch.
