Selder

Selder, S.A. de C.V. (Laboratorios Selder) is a specialized Mexican pharmaceutical manufacturer founded in 1960, with a strong focus on over-the-counter (OTC) healthcare products. While the company originally developed and owned the iconic cold and flu brand XL-3, it sold the brand rights to Genomma Lab in 2012 and now serves as the primary manufacturer for the XL-3 product line. Selder is a leader in softgel capsule technology and high-volume pharmaceutical production, exporting approximately 85% of its output to the United States to serve the Hispanic OTC market. Headquartered in Mexico City, the company operates FDA-registered facilities and provides contract manufacturing services for a variety of small-molecule therapies in the respiratory, analgesic, and allergy categories. Its commitment to international quality standards has established it as a key player in the regional pharmaceutical supply chain.
