It is unclear if use during pregnancy is safe. [1] Clofazimine is a phenazine dye and is believed to work by interfering with DNA. [1] Clofazimine was discovered in the 1950s at Trinity College, Dublin, [6] and approved for medical use in the United States in 1986. [1] It is on the World Health Organization's List of Essential Medicines. [7]

In the 1950s, dapsone was introduced. The search for further effective antileprosy drugs led to the use of clofazimine and rifampicin in the 1960s and 1970s. [125] Later, Indian scientist Shantaram Yawalkar and his colleagues formulated a combined therapy using rifampicin and dapsone, intended to mitigate bacterial resistance. [126]
