Who Owns FiberCon?

FiberCon was originally developed by Wyeth, the American pharmaceutical company, and introduced in the late 1980s as a bulk-forming laxative in caplet form. Its calcium polycarbophil active ingredient absorbed water in the intestine to soften stool and promote regularity, competing in a category dominated by Metamucil psyllium and Citrucel methylcellulose.

The brand's distinguishing feature was format: FiberCon delivered bulk-forming fiber in a swallowable caplet rather than a powder that required mixing, marketed around convenience for consumers unwilling to stir and drink fiber supplements.

Wyeth's consumer health portfolio carried FiberCon through the 1990s and 2000s. When Pfizer acquired Wyeth in 2009, FiberCon moved into Pfizer Consumer Healthcare. The 2019 combination of Pfizer Consumer Healthcare with GSK's consumer business put FiberCon nominally within the joint venture that became Haleon, but the brand was divested before or during that transition.

Foundation Consumer Brands, a Pittsburgh-based OTC portfolio company backed by private equity, acquired FiberCon and began marketing it around 2021, with FDA labeler records showing Foundation as distributor through 2025. In 2026, FDA records shifted distribution to Medtech Products Inc., a Prestige Consumer Healthcare company, returning the brand to the large OTC portfolio environment where it began.

Through its history, FiberCon has remained a single-format brand: coated caplets in 140-count bottles, positioned on the convenience of pill-form fiber.
