Our history of 260 years.

SSP Co., Ltd. is a pharmaceutical company specializing in OTC (over-the-counter) drugs and healthcare products, providing a variety of products to meet health needs for 260 years since its establishment in 1765.

In 2017, SSP became a part of Sanofi, a global healthcare leader headquartered in Paris, France. SSP operated as a part of Sanofi’s consumer healthcare division, Opella. In 2025, Opella became an independent CHC company owned by CD&R, a global private equity.

While SSP enjoys broad consumer support through its antipyretic analgesic “EVE”, allergy medication “Alesion”, L-cysteine vitamin “Hythiol”, and sleep-improving drug “Drewell”, the company will continue to contribute to improving people's health and quality of life through the development of high value-added pharmaceuticals such as “Switch OTC drugs” and the promotion of self-medication.
