Safety and Efficacy of Topical Calcineurin Inhibitors in the Treatment of Facial and Genital Psoriasis: A Systematic Review

Facial and genital psoriasis impairs quality of life and is challenging to treat because of increased percuta-neous penetration and, consequently, increased risk of adverse effects. Topical calcineurin inhibitors are recognized as a valid off-label treatment for these sensitive skin areas, but data on safety and efficacy are limited. This systematic review of the literature in-cluded 24 of 3,322 studies (5 randomized controlled trials, 9 open-label studies, 2 case series and 8 case reports). All studies demonstrated positive efficacy; 11 studies found statistically significant reductions in psoriasis severity. Local stinging, burning and itching were the most common short-term adverse effects and were reported in 18 studies. Topical calcineurin inhibi-tors appear to have an important role in the treatment of facial and genital psoriasis. The drugs are effective and generally well-tolerated with few adverse effects.
