Kirkland Signature Extra Strength Acetaminophen

Kirkland Signature is the private-label brand of Costco Wholesale Corporation. The Acetaminophen product shown is a generic alternative to Extra Strength Tylenol, designed to provide pain relief and fever reduction. The brand was launched in 1995 as a way for Costco to provide high-quality items at consistently lower prices than traditional national brands.

Products under the Kirkland Signature label are manufactured by various third-party suppliers who also produce major national brands. While the specific manufacturer for each batch can vary, the majority of their over-the-counter health products are produced by American pharmaceutical contract manufacturers to meet FDA standards. Costco maintains full ownership and control over the brand's distribution and marketing worldwide.
