Intravenous acyclovir for the treatment of primary genital herpes.

Thirty-one patients with first episodes of genital herpes were randomized in a double-blind fashion to intravenous treatment with saline placebo or acyclovir, 5 mg/kg body weight at 8-hour intervals, for 5 days. The median duration of viral shedding from genital lesions after the onset of therapy was significantly shorter for patients given acyclovir (2 days) than for those given placebo (13 days), p less than 0.001. Viral shedding from the pharynx, cervix, urethra, and urine were also shorter in acyclovir-treated patients. (p less than or equal to 0.01 for each comparison). Local and systemic symptoms were shortened by a mean of 5 days and healing of genital lesions by a mean of 12 days in acyclovir-treated patients. (p less than 0.01). Complications during treatment, such as extragenital lesions or urinary retention requiring catheterization, developed in four patients given placebo and in none given acyclovir. (p less than 0.05). Intravenous acyclovir substantially decreases the symptoms, duration of lesions, and complications of primary genital herpes.
