什麼是「事前預防用藥」?
What is PrEP?
事前預防用藥(下稱「預防用藥」)是一種以口服藥物方式預防愛滋病毒感染的方法。每日定時服藥能大幅降低感染機會。
預防用藥不能取代安全性行為,它亦沒有預防其他性病的能力。要有效預防愛滋病毒感染,須配合其他預防措施,包括使用安全套。
世界衞生組織建議高愛滋病毒感染風險的社群接受預防藥物,當中包括男男性接觸者社群。
現時獲美國藥物及食物管理局認可的預防藥物為 TDF 300毫克 / FTC 200毫克。
其常見副作用為腸胃不適、頭痛和體重下降。其他有機會引起的嚴重副作用包括乳酸中毒、肝腎功能受損、骨密度降低以及加劇乙型肝炎感染。
愛滋病事前預防 PrEP 專題
Pre-exposure prophylaxis (PrEP) involves the use of anti-HIV medicine to prevent HIV infection. Taken orally daily, it can potentially reduce the risk of getting HIV significantly.
PrEP is NOT a replacement of safer sex and it CANNOT protect against other sexually transmitted infections. Other prevention measures including condom use must be in place to prevent HIV infection effectively.
World Health Organisation has recommended PrEP for populations with substantial risk of HIV acquisition, including men who have sex with men community.
The medicine currently approved by US FDA for PrEP is Tenofovir disoproxil fumarate 300mg / Emtricitabine 200mg.
Common side effects are digestive system upset, headache, and decreased weight. Other possible serious side effects include lactic acidosis, liver and kidney problems, bone mineral density loss, and worsening of Hepatitis B infection.
