前言

威而鋼，作為一種治療男性勃起功能障礙（ED）的藥物，自從上市以來，便因其顯著的療效和安全性而受到廣泛的關注和使用。對於威而鋼多久吃一次效果最好？以及服用威而鋼還是「硬不起來」？或服用威而鋼「整天硬邦邦」？本文將詳細探討這些問題，並提供一些相關的建議。

威而鋼多久吃一次效果最好？

威而鋼的主要成分是西地那非（Sildenafil），它通過抑制5-磷酸二酯酶（PDE5）來增強陰莖海綿體的血液流入，從而達到勃起的效果。根據臨床研究和醫學建議，威而鋼通常建議在需要時服用，每天最多一次。這是因為藥物的代謝過程和藥效持續時間約為4至6小時，因此每天服用一次已經足夠。藥師建議最好間隔24小時服用最佳。並不是說服用越多效果越好哦。

用威而鋼還是「硬不起來」？醫師： 6大「服藥NG行為」要避免

男性在服用威而鋼後，大多期待在床上能「大展雄風」，為何實際上陣時小兄弟仍舊「垂頭喪氣」？臺北市立聯合醫院忠孝院區泌尿科程威銘醫師表示，服用威而鋼仍無法正常勃起，不見得與藥物劑量有關，而可能是使用方法錯誤所致。提醒男性在服用威而鋼前，應避免以下6種行為：

用威而鋼還是「硬不起來」？醫師： 6大「服藥NG行為」要避免

1. 服用來路不明藥物

2. 劑量過低影響藥效

3. 太早開始進行性愛

4. 沒有適當刺激陰莖

5. 攝取過量高油飲食

6. 飲酒及娛樂性藥物

服用威而鋼「整天硬邦邦」？

威而鋼俗稱「藍色小藥丸」，是治療勃起功能障礙的藥物。對此，三重好幸福泌尿科診所院長高銘鴻表示，確實有一些服用威而鋼後發生陰莖異常勃起的案例，但相當罕見，適量服用也不會對心臟有害，反而有助於維持勃起。

服用威而鋼「整天硬邦邦」？

高銘鴻在臉書專頁《泌尿科高銘鴻醫師》發文提到，威而鋼並不會讓人整天「硬邦邦」，雖然有一些服用威而鋼後發生陰莖異常勃起的案例，但相當罕見，不用過於緊張，要註意的是，若服藥後沒有「馬上」有感，千萬不要增加劑量或搭配其他藥物，否則可能會產生累積效應，造成身體不適。

長期吃威而鋼副作用有哪些？

長期服用威而鋼(Viagra) 可能會產生一些副作用，包括臉部潮紅、頭痛、視覺模糊、頭暈、肌肉痠痛等。壯陽藥協助許多人再次「抬頭」，但是吃了之後可能因血管擴會張產生頭痛、鼻塞甚至背痛的副作用。泌尿科醫師邱鴻傑曾受訪指出，約有5%的人會有這類的副作用，要等藥物的半衰期過後，副作用才會自然消失。

值得注意的是，除了心血管有狀況的人之外，程威銘表示，若是你是糖尿病患者的話，盡管對壯陽藥的反應可能會比較差，但服用這些藥物一樣是具有保護的效果。

長期吃威而鋼副作用有哪些？

大體上，使用壯陽藥物是相當安全的，即便是長期使用的患者也是如此。不過程威銘也提醒，千萬不要購買未經醫師認可的壯陽藥品，才不會對身體造成意想不到的危害。

總結：長期服用威而鋼應謹慎，務必在醫師指導下使用，並了解可能的副作用。若出現任何不適症狀，應立即就醫.

藥師結語

威而鋼是成熟且廣泛用於治療勃起功能障礙的藥物，卻不是可以解決所有性功能問題的萬能丹，建議服用前先尋求專業醫師的指導，才能夠好好享受威而鋼的好處，且無需擔心藥物的風險。了解藥物的使用頻率、可能的副作用以及注意事項，可以幫助你更安全、有效地使用威而鋼，從而改善性生活質量。

此外，建議每位患者務必在醫師或藥師指導下使用，切勿自行加量或搭配其他壯陽藥物。
長期來看，維持規律作息、控制壓力、改善飲食也是提高治療成功率的重要因素。

Climeworks, which launched in 2009, is among around 140 direct air capture companies globally, but is one of the most high-profile and best funded.
трипскан сайт
In 2021, it opened its Orca plant in Iceland, followed in 2024 by a second called Mammoth. These facilities suck in air and extract carbon using chemicals in a process powered by clean, geothermal energy.

The carbon can then be reused or injected deep underground where it will be naturally transformed into stone, locking it up permanently. Climeworks makes its money by selling credits to companies to offset their own climate pollution.

The appeal of direct air capture is clear; to keep global warming from rising to even more catastrophic levels means drastically cutting back on planet-heating fossil fuels. But many scientists say the world will also need to remove some of the carbon pollution already in the atmosphere. This can be done naturally, for example through tree planting, or with technology like direct air capture.

The advantage of direct air capture is that carbon is removed from the air immediately and “can be measured directly and accurately,” said Howard Herzog, senior research engineer at the MIT Energy Initiative.

But there are big challenges, he told CNN. The concentration of carbon dioxide in the atmosphere has been shooting upward, but still only makes up about 0.04%. Herzog compares removing carbon directly from the air to needing to find 10 red marbles in a jar of 25,000 marbles of which 24,990 are blue.

This makes the process energy-intensive and expensive. The technology also takes time to scale.

Climeworks hasn’t come anywhere close to the full capacity of its plants. Orca can remove a maximum of 4,000 tons of carbon a year, but it has never captured more than 1,700 tons in a year since it opened in 2021. The company says single months have seen a capture rate much closer to the maximum.

The company’s Mammoth plant has a maximum capacity of 36,000 tons a year but since it opened last year it has removed a total of 805 tons, a figure which goes down to 121 tons when taking into account the carbon produced building and running the plants.
