Int J Womens Dermatol.  |  [9][3][2], It is usually not given to children under two years of age. Conversely, methotrexate can increase the occurrence of the anemia caused by sulfonamides because methotrexate also causes folic acid deficiency. In the gut sulfasalazine is broken down (by the normal gut bacteria) into two parts: one part a sulphonamide antibiotic which kills harmful bacteria; and a second part which acts to reduce the process driving inflammation as well as helping to control the overactive immune system.
