What this trial studies
This randomized, placebo-controlled trial examines the combined use of an intravenous immunonutrition vitamin drip and oral melatonin in adults with fibromyalgia. Participants will receive either the active combination or placebo once weekly for five weeks, with assessments of pain, quality of life, sleep, fatigue, and inflammatory markers. Primary outcomes include changes in pain and quality of life using validated scales, along with patient-perceived change and central sensitization measures. Secondary outcomes cover sleep quality, fatigue, and biomarkers. The study is conducted at the Immunonutrition Unit of the University of Thessaly in Greece, led by the university with no listed collaborators.
Why it matters
Potential benefit: If successful, participants could experience reduced pain and better daily functioning and sleep.
How similar studies have gone: Previous reports suggest melatonin and intravenous micronutrient therapy may improve sleep and pain in fibromyalgia, but this specific combination in an RCT is novel.
