Treo Citrus effervescent tablets

Treo is a well-established pharmaceutical brand primarily known in the Nordic region for its pain-relieving effervescent tablets containing acetylsalicylic acid and caffeine. The brand was originally developed in Sweden by the company Leo, which later became part of the broader Nordic pharmaceutical ecosystem.

Today, the manufacturing of Treo is centered in Denmark, where the brand's primary production facilities are located. The brand has transitioned through various corporate hands over the decades, reflecting the consolidation of the global pharmaceutical market. Currently, Treo is owned and marketed by Viatris Inc., a global healthcare company formed in 2020 through the combination of Mylan and Pfizer’s Upjohn division. Viatris is headquartered in the United States and manages the production and distribution of Treo to ensure it remains a pharmacy staple in Sweden and surrounding countries.
