The common claim vs. the evidence

What most answers say — and what the evidence supports

Online answers - including AI answer boxes - most often credit Perrigo as the maker, usually by borrowing from FDA records that tie Perrigo to Kirkland's ibuprofen and minoxidil and from Perrigo's Allegan, Michigan address on those cartons. For this product the FDA route is empty: Kirkland Signature Hydrocortisone Plus is an over-the-counter monograph drug (identifier M017) whose label names only Costco Wholesale, with no ANDA applicant to trace and no 'manufactured by' or 'distributed by' third party on the carton. What does name a maker is Costco's own catalog data: as of August 2026, Costco's product-listing data for the four-pack (item 11893977) carries "L Perrigo Company" in its manufacturer field, so evidence points to Perrigo, the largest US maker of private-label OTC drugs. That field is an internal catalog entry that can name a supplier-of-record rather than the plant, and nothing at tiers 1-3 exists for a monograph drug to corroborate it, which is why the attribution is probable rather than confirmed. Taro Pharmaceuticals and Padagis, the other major US makers of store-brand topical hydrocortisone, are occasionally floated as well, with no evidence behind either.

Tier 4 Costco Wholesale Kirkland Signature 1% Plus Hydrocortisone Cream, 2 oz, 4 ct (Costco Business Delivery product-listing data) Published · accessed August 30, 2026

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 1% Plus Hydrocortisone Cream, 2 oz, 4 ct' (item 11893977) - 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 is the sole route that names anyone: the cream is an FDA over-the-counter monograph drug (identifier M017) with no ANDA applicant to resolve, its FDA label names only Costco Wholesale, and no recall or press report names a maker (the search is documented in checked[]). Under the rubric, mfName as the sole route caps at probable (cream-cheese precedent, DECISIONS 2026-08-10) - the FDA route that would corroborate it does not exist for a monograph drug, so there is nothing at tiers 1-3 to close the attribution. The value passes the sanity check: Perrigo is the largest US maker of private-label OTC drugs and FDA records tie it to Kirkland's ibuprofen, minoxidil, acid reducers and nicotine products.

Frequently asked

Who makes Kirkland Signature Hydrocortisone Plus?

Evidence points to Perrigo, per Costco's own product-listing data: Costco's catalog record for the Kirkland Signature 1% Plus Hydrocortisone Cream four-pack (item 11893977) carries "L Perrigo Company" in its manufacturer field, as of August 2026. That is the only source that names anyone. The cream ships as an FDA over-the-counter monograph drug (identifier M017) with only Costco Wholesale on the label - so, unlike Kirkland's ibuprofen and minoxidil, which trace to a named FDA drug-application holder, there is no application holder to resolve, and a documented sweep of FDA drug-application records, the FDA recall database and news coverage turned up no independent naming. Because the link rests on Costco's internal catalog field alone, the attribution is probable rather than confirmed.

Is Kirkland Hydrocortisone Plus made by Perrigo?

The evidence points that way, on one source. The 'Perrigo' answer long circulated by extrapolation - FDA records tie Perrigo to two other Kirkland drugs, its ibuprofen and its minoxidil, and Perrigo's Allegan, Michigan address appears on those cartons - but this hydrocortisone cream is an over-the-counter monograph drug with no application holder, and its FDA label names only Costco Wholesale. What now supports the Perrigo answer directly is Costco's own product-listing data, which carries "L Perrigo Company" in the manufacturer field for this item. No FDA record, recall or press report corroborates it, and a retailer's catalog field can name a supplier-of-record rather than the plant, so this stays probable, not confirmed. Nothing connects Taro or Padagis, the other store-brand hydrocortisone makers sometimes floated, to this product.

Is Kirkland Hydrocortisone Plus the same as Cortizone-10?

They share the same active ingredient and strength - hydrocortisone 1% - and Costco's own listing says to 'Compare to Cortizone 10 Plus,' which is where the comparison comes from. But nothing indicates they share a maker. Cortizone-10 is a Chattem brand (Chattem is now part of Opella, the consumer-health company Sanofi spun out in April 2025), while Costco's own product-listing data points to Perrigo for the Kirkland cream. Same drug and strength, different makers on the evidence available.

Was Kirkland hydrocortisone cream ever recalled?

No recall is on file for Kirkland Signature Hydrocortisone Plus. The FDA enforcement database returns no Kirkland or Costco hydrocortisone recall at all. Plenty of hydrocortisone recalls exist from generic drugmakers such as Taro, Padagis, and Perrigo's New York unit, but none of them names a Kirkland or Costco product, so the recall route - usually the fastest way a private-label maker gets named - adds nothing here; the Perrigo attribution rests on Costco's own catalog data instead.
