病人被處方抗憂鬱藥。護理師應告知病人大約需多久才會見到療效？

絕大多數抗憂鬱藥物（如選擇性血清素回收抑制劑，SSRIs）並非立即產生作用，其機轉在於調整腦部神經傳導物質受體的敏感度，這是一個緩慢的生理適應過程。病人通常在用藥的前幾週內可能先感受到副作用，而治療效果（Mood elevation）往往需要 2 至 4 週甚至更長的時間才會顯現。護理師必須提供此資訊，以提高病人的藥物遵從性，避免病人因初期無效而自行停藥。

Antidepressants, such as SSRIs, typically require 2 to 4 weeks to produce noticeable therapeutic effects because they work by gradually adjusting neurotransmitter receptor sensitivity. Clients may experience side effects before feeling mood improvement, so it is crucial to educate them on this timeline to enhance adherence. Expecting immediate results within days or weeks is unrealistic, and delaying evaluation until six months is unnecessary.
