Theraflu Extra Strength Cold & Flu

Theraflu is a well-known line of over-the-counter cold and flu relief products. Originally developed by the Swiss pharmaceutical company Sandoz (which later became part of Novartis), the brand has a long history of providing hot-drink-based medicinal treatments for congestion and fever.

Starting in 2015, the brand was part of a major consumer healthcare joint venture between GSK and Novartis. In mid-2022, this division was spun off into a new, independent global consumer healthcare company called Haleon. Today, Haleon is the ultimate owner of Theraflu, managing its production and distribution globally. Manufacturing occurs across multiple international sites including facilities in Switzerland, the United States, and various European locations to meet regional demand.
