Discovered in the 1950s, Clofazimine is a medication used together with rifampicin and dapsone to treat leprosy. Evidence is insufficient to support its use in other conditions, though. It is worth noting that Clofazimine is a phenazine dye, and is also believed to work by interfering with DNA. Always remember to take Clofazimine with food or with a glass of milk. Also bear in mind that this drug has its own annoying side effects such as abdominal pain, diarrhea, itchiness, dry skin, and change in color of the skin. In addition, Clofazimine may also cause swelling of the lining of the gastrointestinal tract, increased blood sugar, and sensitivity to the sun. It is, however, unclear if its use during pregnancy is safe. So, make sure you consult your doctor before taking it.
