PHAZYME is an American over-the-counter digestive health and pharmaceutical brand that specializes in simethicone-based gas and bloating relief products, known for their maximum strength and pharmaceutical-grade quality. PHAZYME originated in the mid-20th century and gained prominence in the 1970s as one of the first high-potency softgel anti-gas formulations in the U.S. market.

Initially launched as a clinical-strength product marketed to physicians, PHAZYME was designed to provide superior relief from gas, pressure, and bloating through simethicone, a non-systemic, FDA-approved anti-foaming agent that works by breaking down trapped gas bubbles in the gastrointestinal tract. Its physical mode of action, rather than chemical alteration of digestion, made it a trusted solution for adults and seniors with sensitive stomachs.

In the 1980s, PHAZYME was acquired by the Block Drug Company, headquartered in Jersey City, New Jersey, which reintroduced it to consumers through retail pharmacies under the slogan “Don’t Make the Antacid Mistake.” This campaign distinguished PHAZYME as a true anti-gas medicine, not an antacid, and helped the product achieve national visibility.

By the early 2010s, PHAZYME was owned by Fleet Laboratories (C.B. Fleet Company, Inc.), a Virginia-based healthcare manufacturer founded in 1869, known for digestive and personal care products. Fleet’s modernization of the line included new dosage formats—Ultra Strength (180 mg), Maximum Strength (250 mg), and Ultimate Strength (500 mg)—each tailored for varying levels of discomfort. These formulations made PHAZYME one of the strongest simethicone-based OTC gas relief products available in North America.

In the following decade, ownership transitioned to Sanofi Consumer Healthcare through its U.S. subsidiary Chattem, Inc., located in Chattanooga, Tennessee. Chattem, a leader in American consumer health since 1879, also manages brands such as Gold Bond®, Icy Hot®, and Selsun Blue®. Under Sanofi’s global leadership, PHAZYME gained access to cutting-edge GMP-certified manufacturing, international research networks, and a wider global distribution footprint spanning North America, Europe, and select regions of Asia.

Today, PHAZYME is produced in FDA-registered, cGMP-compliant facilities, ensuring clinical-grade purity and fast-acting performance through its rapid-dissolving softgel technology. PHAZYME’s commitment to clean formulations—gluten-free, lactose-free, and dye-free—caters to modern consumers seeking safe, effective, and transparent products. As one of the most pharmacist-recommended anti-gas brands in North America, PHAZYME competes alongside Gas-X (GSK) and Equate (Walmart) while maintaining leadership through its high potency and clean-label promise.

Through Sanofi’s sustainability commitments, PHAZYME supports eco-friendly packaging, renewable energy use, and a carbon neutrality target by 2030, reflecting a modern, responsible approach to healthcare manufacturing. It is recognized for its maximum-strength simethicone formulations, scientific credibility, and trusted relief from gas and bloating, making it a leading choice in digestive wellness across the United States and Canada.
