Abstract

Introduction: Gabapentin is an antiepileptic drug that alleviates neuropathic pain. Its oral use reduces the intensity of pruritus in patients receiving chronic dialysis therapy. However, it could lead to toxicity because of the patients' renal deficiency. In this study, we assessed the use of gabapentin topical in treating pruritus in dialysis patients. Methods: This randomized, triple-blinded trial was performed on 80 patients divided into two groups randomly (40 in each group). In intervention group, 92.5% of the patients were on hemodialysis. Patients in intervention and control groups were provided with 5% gabapentin and placebo topical creams every 2 weeks for a month. Both Visual Analog Scale and 12-item Pruritus Severity Score questionnaire were used to evaluate itching intensity and score before treatment, a month, and 2 months after starting treatment in both groups. In addition, the effect of itching on quality of life was investigated with the same questionnaire. Findings: Eighty patients (40 in each group) participated in our study. No complication was found in our intervention group. Itching score significantly decreased after a month and 2 months of follow-up in intervention group (p < 0.001). Discussion: Our results showed that 5% gabapentin topical cream can be effective in reducing itching in different areas of the body. None of our patients reported complications. © 2024 International Society for Hemodialysis.
