Clinical efficacy and safety of intravenous ferric carboxymaltose for treatment of restless legs syndrome: a multicenter, randomized, placebo-controlled clinical trial
結論：FCM produced greater IRLS reduction than placebo (least-squares mean -8.0 vs -4.8; p=0.0036). Fewer FCM patients required additional RLS interventions (32.7% vs 59.4%; p=0.0002). CGI-I response not significantly different (35.5% vs 28.7%; p=0.2987). FCM well tolerated.

Clinical efficacy and safety of IV ferric carboxymaltose in restless legs syndrome: A meta-analysis of 537 patients
結論：Pooled IRLS reduction favoring IV FCM with weighted mean difference -6.03 points (p=0.004). SF-36 improved by +7.44 points (p=0.01). VAS RLS severity decreased significantly (p=0.003). Adverse events more common in FCM (notably nausea) but no significant differences in serious AEs.

Randomized, placebo-controlled trial of ferric carboxymaltose in restless legs syndrome patients with iron deficiency anemia
結論：Significant IRLS improvement from baseline in FCM group (-13.47 +/- 7.38) vs placebo (+1.36 +/- 3.59). Sleep quality significantly improved. At week 52, 61% of FCM-treated subjects remained off RLS medications. No serious adverse events.

Efficacy and safety of iron supplements for restless leg syndrome, a systematic review, meta-analysis, meta-regression, and trial sequential analysis of randomized controlled trials
結論：Overall IRLS reduction MD -5.28 (95% CI -7.66 to -2.90; p<0.0001; moderate certainty). IV iron MD -4.98 (95% CI -7.48 to -2.48; p<0.0001). FCM specifically MD -6.37 (95% CI -10.19 to -2.55; p=0.001). Iron sucrose not significant (p=0.24). Responder RR 2.06 (95% CI 1.49-2.84; p<0.0001; high certainty). Mostly mild AEs; no significant difference in discontinuation (p=0.08).
前往 PubMed
Treatment of restless legs syndrome and periodic limb movement disorder: an American Academy of Sleep Medicine clinical practice guideline
結論：STRONG recommendation (moderate certainty) for IV ferric carboxymaltose in patients with appropriate iron status. CONDITIONAL recommendation (moderate certainty) for ferrous sulfate (oral). Conditional/very-low certainty for IV iron dextran (LMW) and ferumoxytol. Iron studies should be drawn morning, fasting, with 24h iron-containing supplement washout. Aligns with IRLSSG consensus update on iron management for RLS.

📍立場總覽
台灣社群（PTT Doctor-Info／BabyMother／WomenTalk）對鐵用於不寧腿的討論真實存在但相對零散，且高度集中在孕期與缺鐵性貧血族群。多數提及把「缺鐵」當成腳夜間不適的可能原因，建議抽血看鐵蛋白、靠孕婦維他命或鐵劑補充後「比較舒服」，醫療新聞也點出缺鐵性貧血為高危險群。社群整體傾向：補鐵僅在確實缺鐵時對不寧腿有感，並非所有人都有效；不寧腿本身更常被導向神經內科就醫而非單靠補鐵自療。鐵劑相關抱怨多為腸胃副作用。業配密度低，多為孕媽與女性版友自身經驗分享，唯外圍存在大量「補鐵保健品推薦」排行榜式部落格／導購文。
💬社群實感
多數正面（限缺鐵族群）／但有條件——多人反映確認缺鐵後補鐵腳夜間不適「比較舒服」、改善數月，惟強調並非人人有效，不缺鐵者補了無感
破解迷思 社群最常見的 4 個誤解
✓
事實以為「不寧腿＝缺鐵」、所有腳夜間不適補鐵就會好（實際應先驗血看鐵蛋白，不缺鐵者補鐵對 RLS 無益且可能鐵過載）
✓
事實把孕婦維他命／綜合保健品當足量補鐵來源，忽略 RLS 常需血清鐵蛋白偏低（如 <50–75 ng/mL）才需積極補鐵
✕
迷思迷信『鐵劑要空腹吃才有效』而硬撐噁心嘔吐
✓
事實版友直接打臉「不要相信空腹服用才有效的幹話」，隨餐吃才能持續
✓
事實把補鐵當不寧腿的萬用自療法，輕忽應就診神經內科評估（社群也常把腳不寧導向看醫生而非單靠補鐵）
🩹 社群通報的副作用
- 噁心、空腹吃會嘔吐
- 胃不舒服一整天、胃痛
- 便秘（鐵劑常見）
- 長痘痘
