Oral acyclovir therapy of recurrent herpes simplex virus type 2 infection of the hand.

Acyclovir was evaluated as treatment of recurrent herpes simplex virus type 2 infection of the hand in a double-blind, placebo-controlled crossover study. In nine fully evaluable patients, oral acyclovir (2 g/day in three doses for 10 days) initiated during the earliest phase of a recurrence reduced the mean durations (+/- standard deviation) of clinical symptoms from 10.1 (+/- 3.6) to 3.7 (+/- 3.0) days (P = 0.008), signs from 11.1 (+/- 3.7) to 6.2 (+/- 3.3) days (P = 0.024), and viral positivity from 5.3 (+/- 3.8) to 0.6 (+/- 1.1) days (P = 0.011).
