Kirkland Signature Aller-Flo

Kirkland Signature Aller-Flo is a popular over-the-counter allergy relief medication featuring fluticasone propionate as its active ingredient. Designed to treat symptoms of hay fever or other upper respiratory allergies, such as nasal congestion and sneezing, it serves as a budget-friendly alternative to name-brand glucocorticoid sprays like Flonase.

The Kirkland Signature brand is the private label of Costco Wholesale Corporation, an American multinational corporation that operates a chain of membership-only high-volume warehouse clubs. The brand was launched in 1995 to provide high-quality items at prices significantly lower than national brands. While the brand is American-owned, production of its pharmaceutical and health products like Aller-Flo is often outsourced to specialized global manufacturers. Much of the Aller-Flo supply has historically been manufactured by Perrigo Company plc, a major global provider of over-the-counter health products with significant manufacturing operations in Israel.
