Nephrotoxicity is a major concern for patients with psoriasis using cyclosporine. Here, we evaluated the impact of intermittent cyclosporine treatment on nephrotoxicity risk among patients with psoriasis in real‐world clinical practice. We retrospectively reviewed 611 patients with psoriasis treated with cyclosporine between January 2013 and January 2017, 398 of whom were considered eligible for analysis. Eighteen (4.5%) patients showed a greater than 25% increase in serum creatinine levels. Age over 60 years (relative risk [RR], 1.6; p = .015), diabetes (RR, 2.3; p < .001), and obesity (RR, 1.7; p = .011) were the significant risk factors of increased serum creatinine levels in patients with psoriasis. There was no significant association of the treatment duration or cumulative dose of cyclosporine with increased serum creatinine levels. In real clinical practice, intermittent cyclosporine use with regular serum creatinine tests can be used to treat psoriasis relatively safely. Age over 60 years, diabetes and obesity are significant risk factors for cyclosporine‐induced nephrotoxicity.
