HIV PEP and PrEP: A Side-by-Side Guide for Men in Singapore
If you have ever found yourself Googling “HIV medication Singapore” at 2am, you are not alone. Whether you had a recent exposure scare or you are simply trying to be proactive about your sexual health, knowing the difference between PEP and PrEP could genuinely change your life. These two medications are often mentioned together, but they serve very different purposes, and understanding which one applies to your situation is the first step.
Let us break it down clearly.
What Is PEP?
PEP stands for Post-Exposure Prophylaxis. Think of it as an emergency measure; something you take after a potential HIV exposure to stop the virus from taking hold in your body.
HIV PEP is a short course of antiretroviral medication taken once or twice daily for 28 days. It works by blocking the virus from replicating in your system before it has a chance to establish a permanent infection. The critical detail here: it must be started within 72 hours of exposure, and the sooner the better. Every hour counts.
PEP is suitable if you have:
- Had unprotected sex with someone who is HIV-positive or whose status you do not know
- Had a condom break during sex
- Shared needles or injecting equipment
- Been sexually assaulted
It is important to understand that PEP is not a morning-after pill for HIV. It is not 100% effective, and it is not meant to be used regularly as a substitute for other prevention strategies. If you find yourself needing PEP repeatedly, that is a sign it is worth exploring a longer-term approach.
What Is PrEP?
PrEP stands for Pre-Exposure Prophylaxis. Unlike PEP, this is something you take before any potential exposure—consistently, as part of your regular routine.
PrEP is a daily oral tablet (most commonly Truvada or its generic equivalent) that keeps HIV from establishing an infection if you are exposed to the virus. When taken correctly, PrEP is over 99% effective at preventing HIV transmission through sex.
PrEP is typically recommended for men who:
- Have multiple sexual partners or are in relationships where partner status is unknown
- Do not consistently use condoms
- Have had a sexually transmitted infection (STI) in the past six months
- Are in a serodiscordant relationship (where one partner is HIV-positive)
Unlike PEP, PrEP requires commitment and regular follow-up. You will need to see a doctor every three months for HIV testing, kidney function checks, and STI screening to continue safely on the medication.

Common Questions Men Ask
Can I get PEP from a GP?
Yes. In Singapore, PEP is available at selected general practitioner (GP) clinics, polyclinics, and hospitals. You do not necessarily need to go to a specialist, though some clinics are better equipped to advise you.
Is PrEP available in Singapore?
Yes. PrEP has been available in Singapore since 2020 and can be prescribed by GPs and sexual health clinics. The cost varies depending on whether you opt for the branded version or the generic equivalent, which tends to be significantly more affordable.
Will seeing a doctor for PEP or PrEP affect my insurance?
This is a common concern. It is worth checking directly with your insurer, as policies differ. However, more insurers in Singapore are updating their positions on HIV-related consultations as stigma around the topic continues to reduce.
Do I still need condoms if I am on PrEP?
Yes. PrEP protects against HIV specifically, but it does not protect you against other STIs like gonorrhoea, chlamydia, or syphilis. Condoms remain an important part of a comprehensive sexual health strategy.
Taking the Next Step
Knowing about PEP and PrEP is one thing. Acting on that knowledge is another—and it can feel daunting, especially if you are not sure where to start or how to bring it up with a doctor.
