<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;">很多男性對威而鋼充滿好奇，卻常常搞不清楚正確服用方法。什麼時候吃效果最好？一次吃多少合適？服用時又有哪些註意事項？這篇文章幫你一次搞懂。

<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;">如果你想讓威而鋼發揮最佳效果，建議在房事前大約<span style="box-sizing: inherit; font-weight: bold;">1小時服用</span>。為什麼呢？因為威而鋼在服用後約1小時達到血液中最高濃度，也就是作用最強的時候。當然，如果因為時間安排不方便，在性活動前<span style="box-sizing: inherit; font-weight: bold;">0.5到4小時內</span>服用也可以，只是最佳效果可能稍微打折。服用後一般<span style="box-sizing: inherit; font-weight: bold;">0.5～1小時左右就會見效</span>。每個人的體質不同，消化吸收速度也不一樣。如果空腹服用，藥效更快；如果剛吃了高脂肪或難消化的食物，吸收可能會慢一些。簡單來說，提前大約1小時服用是最保險的選擇。

<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;">對大多數男性來說，<span style="box-sizing: inherit; font-weight: bold;">50mg是最常見的推薦劑量</span>。如果效果不理想或出現副作用，可以在醫師指導下進行調整。特殊人群需要減量：<span style="box-sizing: inherit; font-weight: bold;">65歲以上、肝腎功能受損或正在服用紅黴素、蛋白酶抑制劑的人</span>，建議服用<span style="box-sizing: inherit; font-weight: bold;">25mg</span>，避免血液中藥物濃度過高，降低副作用風險。記住，威而鋼是處方藥，一定要在專業醫師指導下服用。
