Who makes Kirkland Signature Ibuprofen 200 mg, 500 Tablets?
As of August 17, 2026, evidence points to Perrigo as the manufacturer of Kirkland Signature Ibuprofen 200 mg, 500 Tablets, but no tier 1–3 source names the link directly.
The common claim
What’s commonly claimed, and what the evidence supports
Advil-versus-Kirkland comparisons usually name Perrigo or LNK International as the maker, and both turn up in FDA records, because Costco sources its ibuprofen from several contract manufacturers at once. The flagship Kirkland Signature Ibuprofen 200 mg coated tablets (NDC 63981-604) are marketed under ANDA 072096, held by Perrigo; other current Kirkland ibuprofen tablet listings (NDC 63981-291 and 63981-393) sit under ANDAs held by LNK International, and the liquid-gel capsules trace to Ascent Pharmaceuticals and Bionpharma. For the standard 200 mg coated tablets the evidence points to Perrigo, but "who makes Kirkland ibuprofen" has no single answer across the line.
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 3
DailyMed's FDA-sourced label "KIRKLAND SIGNATURE IBUPROFEN- ibuprofen tablet, film coated" names Costco Wholesale Company as the labeler (DUNS 103391843), lists NDC 63981-604 (ibuprofen 200 mg, 500-tablet bottle, marketed since 2003), and gives Marketing Category "Abbreviated New Drug Application" with Application Number ANDA072096. No establishment other than Costco appears on the SPL; the maker is identified through the ANDA number.
Tier 3
Drugs@FDA resolves ANDA072096 (the application behind the flagship Kirkland Signature Ibuprofen 200 mg tablets, NDC 63981-604) to sponsor PERRIGO, product IBUPROFEN 200 MG. Graded probable, not confirmed: the ANDA applicant is FDA's responsible party, but the Kirkland ibuprofen line is multi-sourced (see the LNK source), so no single maker covers every pack, and the applicant is not always the physical packer.
Tier 3
Documents the multi-sourcing that keeps this probable rather than confirmed: two other current Kirkland ibuprofen 200 mg tablet listings (NDC 63981-291 and 63981-393) are marketed under ANDA075010 and ANDA075139, both held per Drugs@FDA by LNK (LNK International, the other major US private-label OTC maker). Costco's liquid-filled ibuprofen capsules trace to still other applicants (Ascent Pharmaceuticals, ANDA206999; Bionpharma, ANDA078682, a listing ending December 2026). So "who makes Kirkland ibuprofen" resolves to Perrigo for the flagship coated tablets and to LNK or Ascent for other packs and forms.
