Purpose
The purpose of this study is to examine the effect of 400 mg of oral zinc gluconate on genital warts. Our hypothesis is that there will be a 10% difference in complete clearance of genital warts in the group randomized to oral plus standard of care compared to those randomized to placebo plus standard of care.

Detailed Description:
Clients presenting to the BCCDC STI clinic with genital warts will be randomized to either 400 mg zinc gluconate or placebo (200mg BID) for 8 weeks in addition to the standard of care. Clinical assessment of warts and additional standard treatment will occur every 7-10 days for a maximum of 8 weeks. A telephone call will occur at week 20 to determine if any of the warts have cleared or re-appeared. The appearance of new warts will also be noted. The proportion of subjects who have complete clearance of genital warts at 8 weeks will be compared between groups.
