A blister pack sold by the piece (tingí-tingì).

The company began on March 1, 1945[1] with a single drugstore owned by Mariano Que (d. (2017-04-15)April 15, 2017).[2][4] He named it after Mercury, the messenger of the gods in Roman mythology, whose caduceus is sometimes used as a symbol of medicine. The store began cutting packaged, bulk items into single pieces and selling them individually; this practice is colloquially called tingí-tingì in Filipino. During its foundation, it is the second oldest established drugstore chain in the country (after South Star Drug, which established in 1937 - eight years earlier).

Upon the invitation of Ayala Corporation, Mercury Drug opened its second branch in May 1963 at a developing commercial center in Makati now known as the Ayala Center.

In 1965, Mercury Drug established its landmark branch at Plaza Miranda, Quiapo, Manila, which is notable for its large outdoor LED screen.[5]

In 2001, then trade secretary Mar Roxas described Mercury drug as a "near monopoly" and said it has 70 percent share of the domestic market (hence, it is now facing competition from mentioned-above South Star Drug - which the latter eventually acquired by Robinsons Retail in 2012 - and SM-owned Watsons Philippine franchise).[6]

As of 2017, Mercury Drug has reportedly over 1000 branches across the country.[7] Recently, it opened a new building, MDC100, located in Eastwood City, Quezon City.[8]
