<p style="box-sizing: inherit; border: 0px; font-style: inherit; font-weight: inherit; margin: 0px 0px 1.6em; outline: 0px; padding: 0px; vertical-align: baseline;">威而鋼（Viagra）是全球最受歡迎的壯陽藥之一，也稱藍色小藥丸。主要用於治療男性勃起功能障礙（ED）。許多人關心，長期服用威而鋼是否會產生後遺癥？其實，威而鋼只有短暫的副作用，並不會造成永久性的後遺癥。本篇文章將深入探討威而鋼的副作用、常見誤解及安全使用方式，幫助您正確認識這款藥物。

<p style="box-sizing: inherit; border: 0px; font-style: inherit; font-weight: inherit; margin: 0px 0px 1.6em; outline: 0px; padding: 0px; vertical-align: baseline;">按需服用，不要超量：建議劑量為 50mg，可依個人需求調整至 25mg 或 100mg，但每日不可超過 100mg。

<p style="box-sizing: inherit; border: 0px; font-style: inherit; font-weight: inherit; margin: 0px 0px 1.6em; outline: 0px; padding: 0px; vertical-align: baseline;">避免與硝酸鹽類藥物併用：如治療心絞痛的藥物，以免引起低血壓。

<p style="box-sizing: inherit; border: 0px; font-style: inherit; font-weight: inherit; margin: 0px 0px 1.6em; outline: 0px; padding: 0px; vertical-align: baseline;">避免與大量酒精一起服用：酒精會降低藥效，並可能加重副作用。

<p style="box-sizing: inherit; border: 0px; font-style: inherit; font-weight: inherit; margin: 0px 0px 1.6em; outline: 0px; padding: 0px; vertical-align: baseline;">飯前服用效果更佳：高脂飲食可能影響藥物吸收，因此建議空腹服用。

<p style="box-sizing: inherit; border: 0px; font-style: inherit; font-weight: inherit; margin: 0px 0px 1.6em; outline: 0px; padding: 0px; vertical-align: baseline;">有心血管疾病者應諮詢醫師：若有高血壓、心臟病或其他慢性病，應先諮詢藥劑師。
