HIV PEP in Singapore (Post-Exposure HIV Prevention)
HIV PEP is an urgent preventive treatment after potential HIV exposure and works best when started within 72 hours.
If you have had a recent high-risk encounter, time is of the essence. Wonderhealth Screeners provides confidential assessment & same-day access to PEP when medically indicated.
We understand the anxiety of the “waiting game.” Our clinic offers a safe, judgment-free environment to get you the answers and protection you need immediately.
What Is HIV PEP?
- Short definition: HIV Post-Exposure Prophylaxis (PEP) is a medication combination used to prevent HIV infection after a potential exposure.
- Mechanism: It works by stopping the virus from replicating and establishing a permanent infection in your body.
- Duration: To be effective, the medication must be taken daily for 28 days.
When Should You Start HIV PEP?
Timing is critical. You must start treatment:
- As soon as possible: Preferably within 2 to 24 hours of exposure.
- Latest timeframe: Within 72 hours (3 days).
Do not wait for symptoms. HIV infection often shows no early signs. If you suspect exposure, seek medical advice immediately.
Urgent: The 72-Hour Window
Once the 72-hour window has passed, PEP is no longer effective in preventing HIV. If you are close to this deadline, please visit our clinic or a hospital Emergency Department immediately.
Who May Need HIV PEP?
Our doctors provide a non-judgmental, clinical assessment for anyone who may have been exposed to HIV. Common scenarios include:
- Condom breakage or slippage during sex.
- Unprotected sex (vaginal or anal) with a partner whose HIV status is unknown or HIV-positive.
- Sexual assault.
- Needlestick injury (occupational or non-occupational).
- Sharing of injection equipment.
Note: A risk assessment should always be performed by a clinician to determine if PEP is medically indicated for your specific situation.
How HIV PEP Works
PEP involves a course of 2–3 antiretroviral drugs that work by blocking HIV replication. If the virus cannot replicate, it cannot establish a permanent infection in the body.
- Effectiveness: Efficacy is very high when taken early and consistently.
- Regimen: Usually one or two pills a day for 28 days.
- Disclaimer: The exact medication prescribed varies based on patient evaluation and medical guidelines.

How Much Does HIV PEP Cost in Singapore?
The typical private-clinic range in Singapore is generally between S$1,200 and S$2,500, depending on the specific medication regimen and tests required.
This cost typically includes:
- Medical Assessment
- Medication (Full 28-day course)
- Follow-up HIV testing
At Wonderhealth Screeners, we believe in transparent, “no-shock” pricing. Below are our specific rates for PEP medication packages:
| PEP REGIMEN TYPE | COST (Medication only) |
| 2-Drug Combination | S$1,050 |
| 3-Drug Combination | S$1,800 |
| Branded 3-Drug Combination (e.g., Biktarvy) | S$2,200 |
Side Effects of HIV PEP
Modern PEP medications are generally well-tolerated. However, some patients may experience mild side effects, including:
- Nausea
- Fatigue or tiredness
- Diarrhea or stomach discomfort
- Headache
These side effects are usually manageable and often subside after the first few days. Rare severe reactions can occur, which is why doctor monitoring is required. Most patients can continue their usual daily activities while on PEP.
Testing and Follow-Up After PEP
Testing is a crucial part of the PEP protocol to confirm your status. HIV tests are typically required:
- Before starting PEP: To ensure you are HIV-negative before beginning treatment.
- During treatment: Only if advised by your doctor to monitor side effects (e.g., liver/kidney function).
- After completion: Typically at 1 month and 3 months after exposure.
This follow-up schedule is necessary to ensure final confirmation of your HIV status (seroconversion can be delayed) and to transition you to ongoing prevention methods like PrEP if needed.

Frequently Asked Questions About HIV PEP (Post-Exposure Prophylaxis)
How Soon Do I Need To Start HIV PEP?
You must start treatment as soon as possible, ideally within 2 to 24 hours of potential exposure. It is generally not recommended after 72 hours as it is unlikely to be effective in preventing HIV infection.
Can I Get PEP Without A Prescription?
No, HIV PEP is a prescription-only medication in Singapore that requires a medical assessment by a doctor. You cannot purchase it over-the-counter at pharmacies.
Is HIV PEP Effective?
PEP is highly effective in preventing HIV when started promptly and taken daily for the full 28-day course. While rare, failure can occur if treatment is delayed beyond the window period or if doses are missed.
What Is The Difference Between PEP And PrEP?
PEP is an emergency treatment taken after a potential exposure to prevent infection. PrEP is a daily medication taken before exposure to provide ongoing protection against HIV.
Is PEP Safe For Pregnant Individuals?
Can I Drink Alcohol While Taking PEP?
Do I Need To Abstain From Sex During PEP?
It is strongly recommended to abstain from sex or use condoms consistently while on PEP. This prevents potential transmission to others and avoids re-exposure to HIV during your treatment course.
