All antibiotics:  All antibiotics have some risk of Stevens Johnson Syndrome SJS and Toxic Epidermal Necrolysis TEN, but all antibiotics containing sulfasalazine, commonly known as sulfa, have a high risk. 

Other antibiotics with a high risk include all aminopenicillins, cephalosporins, quinolones (such as Levaquin), and cycline antibiotics (such as Tetracycline), so if you have contracted Stevens Johnson Syndrome SJS or Toxic Epidermal Necrolysis TEN from any of these drugs, you may have a case.  Contact a Dilantin Lawyer
