Background: Insomnia is strongly associated with stimulant use across various populations and for a wide range of substances. It represents a significant clinical problem among individuals with stimulant use disorders, yet treatment guidelines for this specific population are limited. This gap underscores the need for a systematic review to analyze the pharmacological and non-pharmacological treatments for insomnia in individuals with stimulant use disorders. The aim of this review is to determine the efficacy, safety, and limitations of these approaches and their impact on psychiatric symptoms, stimulant use, and adverse events. Methodology: A systematic review was conducted through January–July 2025 using PubMed, Scopus, and Web of Science. The review focused on the management of chronic insomnia associated with stimulant use, including substances such as amphetamines, methylphenidate, nicotine, caffeine, and cocaine. The systematic review was structured in accordance with the PRISMA guidelines, and identified studies were assessed by title/abstract and full-text evaluation. Results: A total of twenty studies were included in the systematic review. Seven studies examined pharmacological interventions, including modafinil, naltrexone/buprenorphine-naloxone, varenicline, combination NRT, and ramelteon. Thirteen studies investigated non-pharmacological approaches, including Cognitive Behavioral Therapy (CBT), Repetitive Transcranial Magnetic Stimulation (rTMS), Electrical Vestibular Nerve Stimulation (VeNS), maximal strength training, electroacupuncture (EA), and probiotics. The majority of interventions demonstrated positive outcomes in reducing insomnia severity, with some participants achieving non-clinical levels. Commonly reported clinical symptoms related to insomnia included difficulty initiating or maintaining sleep, early morning awakening, and sleep dissatisfaction. Conclusions: Both pharmacological and non-pharmacological interventions showed promise. However, the lack of validated guidelines underscores the need for integrated therapeutic approaches that address the complex comorbidity of insomnia, stimulant use, and co-occurring psychiatric conditions.
