Postoperative pain
Supplements studied for postoperative pain.
Overview
Melatonin (WA 56; low effect size, very high evidence, medium trust) has low-strength evidence across 13 studies suggesting it may slightly reduce postoperative pain and analgesic need, though benefits appear small and may not be clinically meaningful. Caffeine (WA 52; low effect size, high evidence, medium trust) may enhance common painkillers after surgery, increasing good pain relief by about 5–10% when added at doses of at least 100 mg.
Beta-Glucan (WA 44; low effect size, low evidence, medium trust) reduced bloating and pain after polyp surgery in one early study. Olive Oil (WA 44; low effect size, low evidence, medium trust) cream applied after Caesarean section reduced pain in one small trial. The heatmap and evidence reviews below compare outcomes.
