A Pasadena vitamin maker and a 1961 trademark.

Mylanta is an American over-the-counter brand whose current range includes liquid antacids in bottles, chewable tablets and anti-gas products. Its early history is tied to Southern California. The Pacific Coast Architecture Database at the University of Washington, in an entry on the Pasadena home of the businessman Arthur O. Hanisch, describes him as president of The Stuart Company, an early maker of vitamin supplements headquartered in Pasadena, founded in 1941, and says the company later had success with Mylanta, “which was trademarked in 1961.”

By the late 1980s the brand belonged to a much larger group. According to the Encyclopedia of Major Marketing Campaigns, in an entry by Mariko Fujinaka published on WARC in January 2000, Mylanta was part of the over-the-counter drug business of ICI Americas Inc. when that business changed hands in 1989.

The buyer was a new company. In the spring of 1989 Merck & Co. and Johnson & Johnson formed a joint venture, Johnson & Johnson-Merck Consumer Pharmaceuticals Co., to sell over-the-counter medicines in North America; Merck was preparing a non-prescription version of its drug Pepcid and had little experience of the consumer market, the same entry says. Later in 1989 the venture bought ICI Americas’ OTC business, and Mylanta with it. Merck said the brand would help the venture move into the antacid market while that Pepcid product was still being developed, the entry adds.

A joint venture, a recall and a sale to McNeil.

The new owners put money behind the name at once. In 1990, the WARC entry says, Johnson & Johnson-Merck hired Saatchi & Saatchi Advertising in New York to create a television campaign for Mylanta, part of a plan to build loyalty to the brand before the venture’s own non-prescription Pepcid reached the market several years later.

An archived copy of mylanta.com from 2005 carries the copyright line “Johnson & Johnson – Merck Consumer Pharmaceuticals Co. 1997-2005,” with an address in Fort Washington, Pennsylvania, and the site at that time was addressed to American audiences only, as it still is.

The joint venture’s last years were overshadowed by manufacturing problems. On 29 November 2010 Johnson & Johnson-Merck announced on mylanta.com that it was recalling a group of Mylanta liquid products and an AlternaGEL liquid in the United States and Puerto Rico in order to update their labelling, after an internal review found that alcohol from flavouring agents was not noted on the packaging; the notice said the recall was not based on adverse events.

The partnership ended the following year. On 29 September 2011 Genetic Engineering & Biotechnology News reported that Merck had sold its half of the joint venture to Johnson & Johnson’s McNeil businesses, together with a manufacturing site in Lancaster, Pennsylvania, and that J&J would hold the exclusive rights to Mylanta, Mylicon and the over-the-counter Pepcid brand in the United States and Canada. Merck kept its rights to Pepcid outside those two countries. The company said the sale fitted its plan to build up its own consumer-products division, which it had gained through its 2009 merger with Schering-Plough, the magazine reported. An archived mylanta.com page from 2017 names McNeil Consumer Pharmaceuticals Company as the owner of the Mylanta trademark.

Design and documentation.

The medicine cabinet is a rule-bound place for a packaging designer to work. A pharmacy-aisle carton has to carry a brand name, a product name and a product category on its front face, and it has to do so beside text whose wording, order and minimum type size are set by a regulator rather than by the designer. In the United States that text is the Drug Facts panel, a fixed sequence of headings in a prescribed layout, and every carton, bottle label and blister card in the category has to make room for it.

That leaves the designer a narrower field than in many consumer categories: colour blocking, a wordmark, a band or stripe that signals a line extension, and the shape of the pack itself. Blister packs add a second printed surface, the foil backing. Bottles and caps carry the same system at a smaller scale.

Each guide that follows looks at who started a brand, who has owned it since, and how its cartons, labels and advertising have changed, and it describes products only by name and category as the company lists them.

A licence, a sitcom catchphrase and a new set of flavours.

Mylanta was off American shelves for several years. On 7 June 2016 Chain Drug Review reported that Infirst Healthcare USA, a subsidiary of the British company Infirst Healthcare Ltd, based in Westport, Connecticut, had brought the brand back to stores nationwide under licence from McNeil. The original product, the trade paper said, had left the US market in 2010 because of supply problems that followed recalls.

Infirst used the return to refresh the range. Chain Drug Review reported a reformulated version of the lemon-mint Maximum Strength liquid, a new vanilla caramel flavour, a honey-chamomile product called Mylanta Tonight, and Mylanta Gas Minis, chewable mini tablets in mint and fruit flavours. Infirst’s other products at the time included Infants’ Mylicon and the Dr. Cocoa children’s range, the report added, and the announcement was made in the name of Infirst’s president, Jamie Barickman.

The same report pointed to the brand’s place in popular culture. Infirst noted that the long-running television sitcom Full House had popularised “Oh, Mylanta” as an exclamation of surprise or stress, so that the name circulated as a catchphrase among people who might never have bought the product.

Today mylanta.com is published by Infirst Healthcare Inc., and its footer states that MYLANTA and the brand’s other registered trademarks, among them the product name COAT & COOL, are “used under license”; the same footer adds that Infirst is solely responsible for the site’s content. The licensing arrangement means that the company selling Mylanta in American stores is not the company that owns the name. English Wikipedia describes the licensor as McNeil Consumer Healthcare, now part of Kenvue, the consumer-health company separated from Johnson & Johnson in 2023. The site lists products including Mylanta Liquid, Mylanta Tonight, All-Family Mylanta, Mylanta ONE tablets and Mylanta Gas Liqui-Tab softgels, and offers a Spanish-language version.

For a design guide, Mylanta shows how a coined name and a familiar bottle can outlast the companies behind them, passing from a Pasadena vitamin maker’s trademark through ICI, a Johnson & Johnson-Merck venture and McNeil to a licensee. Compare Tums and Rolaids, two other American antacid names that have changed hands. For this guide we use blue, teal and cream with a sans, an unofficial interpretation; no product or logo is reproduced.
