Intralesional Acyclovir: A Potential Therapeutic Option for Cutaneous Warts.

The treatment of warts is challenging and the development of an antiviral drug that can eradicate the human papilloma virus (HPV) is difficult. The viral origin of warts suggests that acyclovir, an antiviral drug with a proven efficacy in DNA viruses, may be a potential therapeutic option. To evaluate the efficacy and safety of intralesional acyclovir in the treatment of cutaneous warts. Thirty-one patients with cutaneous warts were allocated into 2 groups. Group A (19 patients) had intralesional acyclovir (70 mg/ml) injected into the warts, while group B (12 patients) received intralesional saline as control. The treatment was repeated at 2 week intervals until complete clearance or for a maximum of 5 sessions. Complete clearance of warts was observed in 52.6%, partial response in 36.8%, and no response in 10.5% of the patients in the acyclovir group. Partial response was reported in 16.7%, and no response in 83.3% of the patients in the control group. A high statistically significant difference was found between the treatment and control groups (P < .01). Adverse effects included pain during injection in 89.5%, blistering in 52.6% and erythema in5.3% of the patients. No recurrence was detected during the follow-up period. Intralesional acyclovir can be an effective and well-tolerated treatment modality for cutaneous warts.
