What Can We Help With?

I Want to Protect Myself from HIV

HIV PrEP. Daily medication for ongoing protection before any exposure.

I Want to Get Tested for STIs

STI Screening. Rapid results from 15 minutes, full panels within 72 hours.

I May Have Been Exposed to HIV

HIV PEP. Emergency medication that must be started within 72 hours.

HIV PrEP: Protection Against HIV Before Exposure

HIV Pre-Exposure Prophylaxis (PrEP) is a medication that significantly reduces the risk of contracting HIV. It’s designed for HIV-negative individuals who are at higher risk of exposure.

PrEP may be worth considering if:

You have a partner who is HIV-positive.
You have multiple sexual partners or partners of unknown HIV status.
You regularly engage in unprotected sex.
You have recently been diagnosed with another STI.
You use injection drugs.

Daily or On Demand: Two Ways to Take PrEP

Not everyone needs a pill every day.

The schedule depends on whether your risk is ongoing or confined to a short window.

Daily PrEP: one tablet a day, for continued or unpredictable risk

On-demand PrEP: taken around a defined period, such as travel or a new relationship

Your doctor recommends the schedule after discussing your circumstances

You can move between the two as your situation changes

STI Testing: 6 Warning Signs to Know

Unusual discharge from the penis or vagina

Sores, blisters, or ulcers around the genitals, mouth, or anus

Unexplained rashes or lumps in the genital area

A burning sensation or discomfort when urinating

Pain during or after sexual intercourse

Flu-like symptoms such as fever, fatigue, or swollen glands shortly after exposure

HIV PEP: Protection After Potential HIV Exposure

HIV Post-Exposure Prophylaxis (PEP) is an emergency course of medication that can significantly reduce your risk of HIV infection if taken soon after a potential exposure.

When to consider PEP:

If you've had unprotected sex

If you've experienced a condom failure

After any other high-risk exposure event

Frequently Asked Questions

Is My Visit Completely Confidential?

Yes. All consultations and test results are handled under strict medical confidentiality. The clinic’s location on the second floor of an HDB block adds a further layer of practical privacy for patients who prefer it. Your visit remains your business alone.

I Have No Symptoms. Do I Still Need to Get Tested?

Yes. Many STIs (including HIV, chlamydia, and gonorrhoea) are commonly present with no symptoms at all. The only reliable way to confirm your status is to get tested. Early detection makes treatment significantly more straightforward and prevents onward transmission.

How Quickly Will I Receive My Screening Results?

Rapid HIV and syphilis tests deliver results in 15 to 20 minutes. Comprehensive screening panels are typically returned within 72 hours, which is the standard clinical turnaround time across sexual health clinics in Singapore.

I Think I Was Exposed to HIV Less Than 72 Hours Ago. What Should I Do?

Contact the clinic immediately. HIV PEP must be started within 72 hours of a potential exposure, and ideally within 48 hours, to have the strongest chance of being effective. Same-day consultations are available, and urgent out-of-hours arrangements can be made where possible.

What Is the Difference Between HIV PEP and HIV PrEP?

PEP is an emergency course of medication taken after a potential exposure to HIV. It must be started within 72 hours. PrEP is a daily preventive medication taken before any potential exposure occurs, suited to individuals who are at ongoing risk. If you are unsure which applies to your situation, a doctor can advise during a consultation.

Will My Employer, Insurance Company, or Family Be Notified?

No. Your visit, consultation, and results are strictly confidential between you and your doctor. Nothing is shared with any third party without your consent.
