Brief summary (from the registry)

According to the World Health Organization (WHO) Global Burden of Disease study, back pain is one of the conditions impacting disability the most worldwide.Pain medication use in patients with chronic back pain is substantial, but the efficacy of commonly used analgesics such as paracetamol, non-steroidal anti-inflammatory drugs (NSAIDs), muscle relaxants and opioids compared with placebo are modest, with effects typically less than 10 points on a 0-100 pain scale. Importantly, these analgesics are not harmless due to gastrointestinal and cardiovascular side-effects (NSAIDs) and risk of dependency and addiction (opioids). This often leave general practitioners without good treatment options for many patients with chronic low back pain. More than half of patients with chronic back pain also have sleep problems (i.e. insomnia), which negatively affect daily function, general health and quality of life. Research suggest that insomnia has negative effects on pain processing, and although the relationship between pain and insomnia is bi-directional, insomnia is considered to be a stronger predictor of pain than pain for the development of insomnia. Melatonin is a widely available drug worldwide, and well known for its use in people with sleep disorders and jetlag. Melatonin is a naturally occurring hormone excreted by the pineal gland that is part of regulating the circadian rhythm (sleep-wake patterns). Unlike commonly used drugs to treat back pain, the safety profile of melatonin is favorable with no adverse events of major clinical significance reported in the treatment of sleep disorders. In recent years, some preliminary studies have showed a promising effect of Melatonin for treatments of pain. A meta-analysis reported an effect size of 0.65 (95%CI 0.34 to 0.96) of Melatonin (doses ranging between 3-10 mg before sleep) compared with placebo in reducing pain in patients with non-musculoskeletal chronic pain (e.g. migraine, irritable bowel syndrome, burning mouth syn…

(will be checked by the question: 'In the past 3 months, how often did your back pain limit your life or work activities? - response options: 'never'; 'some days'; 'most days'; 'every day') * Average pain intensity of 4 or higher on 0-10 Numeric Rating Scale \[NRS\] in the past 7 days (ranging from 'no pain' to 'worst imaginable pain'). * All fertile women must use safe contraception (Spiral, birth control pills, contraceptive patch, contraceptive vaginal ring or gestagen injections) for 3 weeks before and 1 week after the trial. If the participants' normal lifestyle includes sexual abstinence, they do not have to use contraception.

A woman is considered non-fertile if she is sterilized, hysterectomized, bilateral oophorectomized or is postmenopausal. A woman is considered postmenopausal when vaginal bleeding has been absent for 1 year (reported by the participant). Exclusion Criteria: Patients will be excluded based on any of the following exclusion criteria: * Known abuse of alcohol or other substances * Self-selected non-user of e-boks * Opioid use (reported by participant) * Known malignancies within past 6 months (reported by participant) * Known fractures within past 4 months (reported by participant) * Known lumbar radiculopathy (reported by participant) * Known spinal stenosis (reported by participant) * Severe psychiatric disorders and/or psychotic symptoms evaluated by the investigator (reported by participant) * Suicide and self-damage thoughts (reported by participant) * Inflammatory/autoimmune arthritis (reported by participant) Patients with contraindications to Melatonin according to the Danish Medicines Agencys approved product information: * Moderate to severe kidney insufficiency (GFR \< 30 mL/min) * Moderate to severe liver insufficiency (ALAT must not be elevated more than 3-fold over highes…
