Who Makes Pepto Bismol?
Pepto Bismol is made by Procter & Gamble. The brand has been continuously produced since 1901 and P&G acquired it from Norwich Pharmacal in 1982.
Quick Answer
Pepto Bismol is made by Procter & Gamble. P&G has owned the brand since 1982, when it acquired Norwich Eaton Pharmaceuticals (part of Morton Norwich Products) for $371 million.
Pepto Bismol is manufactured at P&G facilities in Greensboro, North Carolina and Guanajuato, Mexico. The active ingredient bismuth subsalicylate has been used continuously since the product was first sold as "Bismosal" in 1901.
The Parent Company
Procter & Gamble is a Cincinnati, Ohio-based consumer goods company with more than $80 billion in annual revenue. Its Health Care segment includes Pepto Bismol along with Vicks NyQuil and DayQuil, Prilosec OTC, Metamucil and ZzzQuil.
Pepto Bismol is one of the top three brands in the US upset stomach category, competing mainly with Imodium (Kenvue) and Kaopectate (Chattem/Sanofi).
How Pepto Bismol Started
Pepto Bismol was created in 1901 by a New York physician who was looking for a treatment for infant cholera. It was originally sold as "Bismosal: Mixture Cholera Infantum".
The Norwich Pharmacal Company (based in Norwich, New York) took over marketing in the 1910s and renamed the product Pepto-Bismol. The pink color and mint flavor became the brand signature, and the "Nausea, Heartburn, Indigestion, Upset Stomach, Diarrhea" jingle became a fixture in American advertising in the 1970s.
Norwich was acquired by Morton Salt in 1969, forming Morton Norwich Products, which sold Norwich Eaton Pharmaceuticals to Procter & Gamble in 1982.
Where Pepto Bismol Is Made
Greensboro, North Carolina is the primary US manufacturing site for Pepto Bismol liquid, caplets and chewable tablets. Guanajuato, Mexico is the secondary site serving the US and Latin American markets.
Bismuth subsalicylate active ingredient is manufactured by a small number of specialty suppliers, including Emerald Kalama Chemical (part of Vertellus) and MCP HAHNEMANN in Germany.
What Pepto Bismol Actually Does
Bismuth subsalicylate has three effects. It coats the stomach lining (reducing irritation), has mild antimicrobial activity (helpful for traveler's diarrhea) and has anti-inflammatory salicylate activity (like a very mild aspirin).
The bismuth also reacts with sulfur in the mouth and gut, which is why Pepto Bismol can temporarily turn the tongue and stool black. That is harmless and resolves within a day or two after stopping the product.
How Pepto Bismol Compares To Rivals
Imodium (loperamide, Kenvue) works differently. Loperamide slows gut motility, while Pepto Bismol coats and mildly disinfects. Doctors often recommend Pepto Bismol for traveler's diarrhea and Imodium for acute non-infectious diarrhea.
Kaopectate switched formulas years ago and now also uses bismuth subsalicylate, so at the pharmacy shelf level it is essentially the same active ingredient as Pepto Bismol.
Store brand bismuth subsalicylate (Equate, Up & Up, Kirkland Signature) is chemically identical to Pepto Bismol at the same concentration.
How To Trace Any Product Back To Its Manufacturer
- Read the fine print on the label. US and EU packaging law requires either the manufacturer name or a "distributed by" address. That is your starting point.
- Search the company's SEC filings. Public parent companies list subsidiaries and manufacturing sites in their 10-K annual reports.
- Check the FDA or USDA establishment number. For food, drugs and cosmetics, the plant of origin can often be looked up in public regulatory databases.
- Follow the money. Press releases about acquisitions and joint ventures are the fastest way to spot who really controls a brand today.
Frequently Asked Questions
Who owns Pepto Bismol? Procter & Gamble, since 1982.
Why does Pepto Bismol turn your tongue black? Bismuth reacts with tiny amounts of sulfur in the mouth to form bismuth sulfide, which is black. It is harmless.
Is Pepto Bismol safe for children? The regular product is labeled for ages 12 and up because bismuth subsalicylate contains salicylate (like aspirin), which is linked to Reye syndrome in children with viral illness. Kids' Pepto uses calcium carbonate instead.
Where is Pepto Bismol made? Procter & Gamble plants in Greensboro, North Carolina and Guanajuato, Mexico.
What This Means For The Shopper
When you understand who actually makes Pepto Bismol, a few practical shopping habits fall into place. First, corporate ownership tells you where product safety recalls and reformulations come from. Second, it tells you which store brand alternatives are chemically or functionally equivalent, because generic makers usually target the same reference product. Third, it explains pricing behavior: brands owned by big consumer conglomerates rarely drop below a floor price for long, because that floor protects a very large marketing and distribution investment.
Corporate ownership also shifts over time. The same brand you grew up with may be on its third or fourth parent company. That is why any answer to "who makes Pepto Bismol" should be dated. The current parent listed on the label today is the one legally responsible for the product, regardless of the packaging design or advertising campaign you remember from years ago.
If you want to double check, the fastest confirmation is the label itself. Look for the "Distributed by" or "Manufactured by" line in the fine print. The company name and city on that line is the current legal manufacturer or distributor of Pepto Bismol for your market, and that is the entity you would contact for a product complaint, safety concern or ingredient question.
What To Watch Going Forward
Consumer packaged goods ownership keeps consolidating. In the last five years alone, several major consumer health and beverage brands have moved between parent companies through spin-offs, sales and joint ventures. Expect more of the same over the next five years, especially as private equity and family holding companies continue to reshape mid-cap consumer brands.
If you buy Pepto Bismol regularly and care about who profits from your purchase, it is worth checking the label every year or two. Ownership changes are usually announced in trade press but rarely make consumer headlines, so most shoppers miss them until the packaging gets a subtle redesign to reflect the new parent company.
Bottom Line
Pepto Bismol has been on shelves for more than 120 years and has been a Procter & Gamble brand since 1982. The pink liquid formula is still made in North Carolina, and store brand bismuth subsalicylate at the same strength is the same medicine.
