Haleon plc is a British multinational consumer healthcare company with headquarters in Weybridge, England. It is one of the largest consumer healthcare businesses in the world, with brands including Sensodynetoothpaste, Panadol and Advilpainkillers, and Centrumvitamins. The company was projected to be a global leader in over the counter medicines with a 7.3 per cent market share in 2022.
GSK and Pfizer merged their consumer healthcare businesses in 2019. GSK owned just over two thirds of the joint venture, and Pfizer owned the remainder. Annual sales were around £10 billion across 120 markets in 2020. GSK then announced plans to spin off Haleon in 2022 to give the "tired drugmaker extra focus and firepower by gearing up and hiving off the consumer division," according to Reuters. Unilever offered £50 billion for the business in 2022, which GSK rejected. Nestlé examined the possibility of a bid in conjunction with Reckitt. In October 2023, GSK reduced its ownership in Haleon to 7.4%, and in January 2024 it further reduced its ownership to 4.2%.
In August 2023, Haleon sold its Lamisilantifungal brand to Karo Healthcare AB for £235 million, and in February 2024, Haleon sold its ChapStick lip care brand to Yellow Wood Partners for £401 million.
In March 2024, Pfizer reduced its share in Haleon from 32% to 24% per cent by selling 630 million shares in a public offering.
Further sales followed: in April 2024, Haleon announced that it would close its Sensodyne toothpaste factory in Maidenhead, moving that manufacturing to Slovakia, and it outsourced mouthwash manufacturing to an unrelated company and, in September 2024, the company completed the sale of its non-US nicotine replacement therapy business to Dr. Reddy's Laboratories in a deal worth £458 million.
In March 2025, Pfizer sold its entire stake in Haleon for £2.5 billion ($3.24 billion), exiting the consumer healthcare business it helped create by its 2019 joint venture with GSK.

Notes
↑In 1993, Warner Lambert and Wellcome created a joint venture with both companies merging their OTC products into a joint venture, the Wellcome OTC brands such as Calpol and Actifed; Glaxo also made a agreement with Warner Lambert in 1994 for the distribution of Zantac. In 1995, Glaxo and Wellcome merged to form Glaxo Wellcome which saw its OTC joint venture with Warner Lambert to now include Calpol, Actifed, and Zantac. In 1996, Warner Lambert bought out Glaxo Wellcome's stake in the joint venture, this caused Calpol, Actifed, and Zantac to be owned by Warner Lambert in most countries, however Glaxo Wellcome retained their OTC division in select countries such as the Philippines, Indonesia and South Africa. In 2000, Glaxo Wellcome and SmithKline Beecham merged to form GSK, in some countries where Glaxo Wellcome retained their OTC division, the remaining OTC division of Glaxo Wellcome also merged with SmithKline Beecham's OTC.
