Who Makes Kirkland Ibuprofen? (All You Need to Know)

Who Makes Kirkland Ibuprofen

Have you ever asked yourself or your friend who makes Kirkland Ibuprofen? Well, you are at the perfect place to find the answer to such a question.

Kirkland Signature Ibuprofen is manufactured by another medication producer called Perrigo. Though it’s not the company responsible for making Advil, comparisons are made between Costco ibuprofen and Advil on the Kirkland Signature packaging. Costco’s ibuprofen is not made by Johnson & Johnson, the company behind Motrin IB. 

Some of Costco’s Kirkland Signature products are made by well-known manufacturers that allow that relationship to be clearly displayed on the packaging and labels of those items. Others have chosen to remain anonymous in that regard. We explored this Costco product to uncover what we could. Read on to see what we found out.

Who Makes Kirkland Ibuprofen?

We’ll start with who we know doesn’t make Kirkland ibuprofen. First off, Costco doesn’t make it. Costco doesn’t make any of the Kirkland Signature products.

The company does have a hand in the planning of products; however, the manufacturing and packaging is done by other well-established manufacturers who’ve built factories to make consumer products.

We also know that Johnson & Johnson is not the producer behind the Kirkland Signature ibuprofen. Johnson & Johnson manufactures and distributes Motrin IB. If you look on the back of the packaging for Kirkland ibuprofen, you’ll find the following statement:

“This product is not manufactured or distributed by Johnson & Johnson Consumer Inc., distributor of Motrin IB.”

The producer of Kirkland ibuprofen is Perrigo, a company that was originally founded in the 1800s in Michigan. Today, Perrigo is a thriving and growing company that does business all around the world.

Why Doesn’t Costco Make Kirkland Signature Products?

Costco’s mission is to bring high quality products to the masses at affordable prices. They do this by striking deals with companies to sell popular brand name products for a price closer to wholesale than retail. 

Costco also does this by selling items under its Kirkland Signature brand. Costco picks which product lines it wants to offer items from draws up plans for the chosen products, and enters into contracts with third parties willing to manufacture the items for them at pre-existing factories already being used for the same thing.

The business model Costco works under allows the company to price Kirkland Signature products lower than big brand items that sit on the shelves next to them.

Costco cuts a lot of overhead costs by having other manufacturers produce items for them. That overhead expense saving keeps the prices down for consumers.

That is the date the company can guarantee the medication to be at full potency through. Should you take the pills after that date, they could be slightly less effective.
