本配對為純 OFF-LABEL 處方藥使用 (FDA/EMA/TFDA 均僅核准 minoxidil 口服錠用於頑固性高血壓 10–40 mg/d，並帶黑框警告；TW 衛署藥輸字第 007538 號)，無任何皮膚科適應症之 pivotal RCT。

證據主要為 Perera & Sinclair 2017 回顧性研究 (n=36)、2022 多中心回顧分析 (n=105+105) 與 2020 系統性回顧+IPD pooled-analysis (n=442, 14 studies)，加上 2024 AAD/JAAD Modified Delphi 共識 86% 同意「直接受益」並由 Cleveland Clinic 皮膚科臨床採用 (0.625–1.25 mg/d)；但缺乏 placebo-controlled RCT，Mayo Clinic 與 Harvard Health 在 TE 適應症脈絡下未背書，故獨立給 C — 與 L1 Examine (C) 一致，較 L5 主流意見之 supportive 略保守 (因 RCT 缺口與處方安全訊號)。

Minoxidil belongs to the drug class of direct-acting peripheral vasodilators.

PTT hair_loss 板網友普遍認為口服低劑量 Minoxidil（洛寧錠）對落髮有效，但初期休止期落髮（shedding period）比外用更明顯，「會掉到懷疑人生」屬正常換髮現象，需撐過 2-6 週至半年。多數使用 1/4 至 1/2 顆 10mg 洛寧錠（2.5-5mg/日），但需特別提醒：此為 OFF-LABEL 用法（FDA 僅核准 10-40mg 治療高血壓，未核准任何落髮適應症），口服需經皮膚科醫師處方並監測血壓、水腫、心悸等副作用。針對純粹休止期落髮（telogen effluvium）社群討論主要聚焦於 AGA 共病情境，較少單獨用於急性 TE。
💬社群實感
意見分歧
破解迷思 社群最常見的 5 個誤解
✓
事實誤以為初期 shedding（落髮期加劇）代表藥物無效或惡化，實際上是毛囊從休止期轉入生長期的正常換髮現象
✓
事實誤以為洛寧錠是落髮專用藥，實際上為高血壓 OFF-LABEL 用法，FDA 未核准任何落髮適應症
✓
事實誤以為口服效果一定比外用好，PTT 網友反映「個人感覺生髮效果跟外用 5% 的差不多」
✓
事實誤以為一顆 10mg 是標準劑量，實際落髮用量為 1/4 至 1/2 顆（2.5-5mg），高血壓用量才是 10-40mg
✓
事實誤以為休止期落髮（純粹 TE）可單用 LDOM 治癒，實務上多搭配 finasteride/dutasteride 處理共病 AGA
