Who makes Kirkland Signature Minoxidil 5% (Men's Extra Strength Hair Regrowth Solution and Foam)?
As of July 6, 2026, evidence points to Perrigo as the manufacturer of Kirkland Signature Minoxidil 5% (Men's Extra Strength Hair Regrowth Solution and Foam), but no tier 1–3 source names the link directly.
The common claim
What most answers say — and what the evidence supports
Store-brand hair-regrowth roundups generally credit Perrigo, the largest US private-label OTC drugmaker, and FDA drug records line up with that across both forms. The 5% solution (NDC 63981-032 / 63981-798) is marketed under ANDA 075598, whose Drugs@FDA applicant is Perrigo, and its carton carries a "Packaged By Perrigo, Allegan, MI" line; the 5% foam (NDC 63981-294) is marketed under ANDA 091344, whose applicant is Perrigo Pharma Intl, with a "Made in Israel — Distributed By Perrigo" carton line. Both signals are indirect — openFDA's NDC manufacturer_name only names the Costco labeler, the maker is reached through the ANDA join, an ANDA holder is not always the physical maker, and the carton language is packaging/distribution rather than synthesis — 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 "KIRKLAND SIGNATURE MINOXIDIL- minoxidil solution" names Costco Wholesale Company as labeler/packager (DUNS 103391843), lists NDC 63981-032-16, 63981-032-40 (and the sibling 63981-798; minoxidil 5% topical solution, men's extra strength), and gives Marketing Category "Abbreviated New Drug Application" with Application Number ANDA075598. Beyond the Costco labeler line, the carton text reproduced on the SPL reads "Packaged By Perrigo® Allegan, MI 49010 Rev 10-19" — an on-carton naming of Perrigo as physical packager. The deterministic maker link runs through the ANDA number (resolved to Perrigo in the Drugs@FDA source below), corroborated by this Perrigo carton statement.
Tier 3
Drugs@FDA resolves ANDA075598 — the application behind the Kirkland Signature Minoxidil 5% solution (NDC 63981-032 / 63981-798) — to sponsor PERRIGO, product "MINOXIDIL EXTRA STRENGTH (FOR MEN)", minoxidil 5%. Perrigo is the largest US maker of private-label OTC drugs. Graded probable, not confirmed: the openFDA NDC manufacturer_name only echoes the labeler (Costco), so the maker is reached via the two-table NDC→ANDA→sponsor join; the ANDA applicant is FDA's responsible party but is not guaranteed to be the physical drug manufacturer, and the on-carton "Packaged By" line is packaging, not synthesis. Topical-minoxidil ANDAs are commonly multi-sourced across labelers.
Tier 3
DailyMed "KIRKLAND SIGNATURE MINOXIDIL- minoxidil aerosol, foam" (NDC 63981-294-01, 63981-294-06), labeler Costco Wholesale Company, Marketing Category "Abbreviated New Drug Application", Application Number ANDA091344. The carton text on the SPL reads "Made in Israel. Distributed By Perrigo® Allegan, MI 49010 Rev 07-21" — the foam form is manufactured in Israel (Perrigo operates manufacturing there) and distributed by Perrigo, showing the foam, like the solution, traces to Perrigo.
Tier 3
Drugs@FDA resolves ANDA091344 — the Kirkland Signature Minoxidil 5% foam (NDC 63981-294) — to sponsor PERRIGO PHARMA INTL, product "MINOXIDIL", aerosol/foam. Both Kirkland minoxidil forms (solution and foam) therefore resolve through the NDC→ANDA→sponsor join to Perrigo entities — a cleaner single-source picture than Kirkland's ibuprofen line, which traces to several different applicants. Still probable, not confirmed, for the same reason the solution is: the ANDA holder is FDA's responsible party, not necessarily the physical packer.
