Conclusion: Different interventions (GABA-analogues, kappa-opioid receptor agonists, cromolyn sodium, montelukast, fish-oil/omega-3 fatty acids and topical capsaicin compared to placebo) were effective for uraemic pruritus. GABA-analogues had the largest effect on pruritus. Rifampin, naltrexone and flumecinol tended to be effective for cholestatic pruritus. However, therapies for patients with malignancies are still lacking. Due to the small sample sizes in most meta-analyses and the heterogeneous methodological quality of the included trials, the results should be interpreted cautiously in terms of gener

What the research says
Systematic reviews and meta-analyses from PubMed, with their published conclusions.
3+ meta-analyses or systematic reviews and 10+ randomized controlled trials in humans. The grade measures how much human research exists — read the conclusions below for what it found.
Conclusion: In this systematic, review we present information relating to the effectiveness and safety of the following interventions: intralesional bleomycin; cimetidine; contact immunotherapy; cryotherapy; duct tape occlusion; formaldehyde, glutaraldehyde; homeopathy; photodynamic treatment; pulsed dye laser; surgical procedures; topical salicylic acid; and zinc sulphate.
PubMed 21726478 ↗Conclusion: Levetiracetam also shows benefit with a good safety profile; however, further study is required. Given the benign nature of recurrent febrile seizures, and the high prevalence of adverse effects of these drugs, parents and families should be supported with adequate contact details of medical services and information on recurrence, first aid management, and, most importantly, the benign nature of the phenomenon.
PubMed 34131913 ↗Conclusion: Evidence on whether zinc supplementation can reduce the incidence of otitis media in healthy children under the age of five years living in low- and middle-income countries is mixed. There is some evidence of benefit in children being treated for marasmus (severe malnutrition), but this is based on one small trial and should therefore be treated with caution.
