Cytosine arabinoside for varicella zoster: a second look.

Herpes zoster and disseminated herpes zoster, or varicella (V-Z), continue to be dreaded complications of patients with immunosuppression. Currently, there is no available therapy for V-Z, except for general supportive measures. Seven cases of V-Z are presented, showing the results of cytosine arabinoside administration when given as an intermittent intravenous infusion. The results compare favorably with previously unsuccessful continuous intravenous infusion. It is suggested that further evaluation of the intermittent administration of cytosine arabinoside for V-Z would be worthwhile.
