She also developed a pancytopenia with a neutropenia of 0.77 x 10(9)/l (normal range 2-7.5 x 10(9)/l), but was treated with cyclosporin and granulocyte colony stimulating factor and made a full recovery. o Int J Dermatol. 1989 Sep;28(7):441-4.
  20. 20. Drug-induced toxic epidermal necrolysis treated with cyclosporin. Renfro L, Grant-Kels JM, Daman LA.  Division of Dermatology, University of Connecticut Health Center, Farmington.  Abstract  A 35-year-old woman developed toxic epidermal necrolysis secondary to phenytoin. Because the life-threatening eruption was resistant to prednisone and high-dose methylprednisolone therapy, cyclosporine therapy was initiated. Within 24-48 hours, the eruption stabilized and the patient improved.
