Introduction The clinical effect of imiquimod stems from cytokine-induced activation of the immune system. A randomised study was conducted to study the efficacy and safety of daily applications of 5% imiquimod cream in female patients with external genital warts and MC.
Methods Patients were randomised to receive daily applications of 5% imiquimod cream for a maximum of 16 weeks. Before bedtime patients rubbed the study cream into clean, dry, lesional skin until it disappeared and washed the area with soap and water 8 ± 2 h after application. To investigate wart and MC recurrence, patients who had complete clearance of their baseline lesions at any time during the treatment period stopped treatment and entered a 12-week treatment free follow-up period. Patients were evaluated weekly for the first 4 weeks and every 2 weeks thereafter for the remainder of the 16-week treatment period as well as during the 12-week follow-up period.
Results The clearance rate of lesions was 75% in genital MC patients and 50% in patients with genital warts. Erythema was the commonest adverse reaction seen 24% patients with the use of 5% imiquimod. Other side effects were excoriation seen in 16% patients, erosions in 10% patients, excoriation in 6% patients and pain was seen in 4% patients.
Conclusions Nonspecific inflammation and dermatitis can occur during use of imiquimod for genital warts and molluscum.Fortunately, after completion of the therapy, the skin often heals with barely any scarring.
