HIV PrEP is an extremely effective way of protecting yourself from HIV. It is currently one of the central pillars in our efforts to end the HIV epidemic in the world.
When someone is exposed to HIV through sex or injection drug use, PrEP can help stop the virus from establishing a permanent infection in the body.
HIV PrEP can be taken in several different ways depending on your unique lifestyle. The most common and effective way to take it is with a daily dose – a single tablet taken at around the same time every day. In medical studies, this has been shown to provide the best level of protection against HIV. Also, this schedule is easy to remember and adhere to, thereby reducing the chance of consuming the wrong amount of medication at the wrong time.
The medication currently recommended for HIV PrEP has also shown to be safe and effective for long-term use and rarely causes any significant side effects.
Because no prevention strategy for sexually active people is 100% effective, individuals taking PrEP are still encouraged to use other effective prevention strategies to maximally reduce their risk, including:
• Using condoms consistently and correctly
• Getting HIV and STD testing with partners
• Choosing less risky sexual behaviours, such as oral sex or mutual masturbation
• For people who inject drugs, getting into drug treatment programs and using sterile equipment
The more prevention options patients choose, the greater their protection. Some HIV prevention strategies, such as using condoms, can also provide protection against other STDs, which PrEP does not prevent.

HIV PrEP is the so-called “Event Based PrEP.” This regimen is for people who have decided that they do not want to take HIV PrEP daily and only want to take it prior to an event.
The regimen requires the the individual to take 2 tablets of the HIV PrEP medicine between 2 to 24 hours prior to the event, followed by 1 tablet on the day of sexual intercourse, and a final tablet 1 day after after sex. Medical studies show that the protection provided against HIV for this regime is not as good as if the medicine is taken daily.
Furthermore, this regimen is more complex and therefore increases the risk of the individual taking the wrong amount of medication at the wrong time.
Descovy (brand name) is a FDA approved new drug combination of tenofovir alafenamide (TAF) + emtricitabine for use as HIV PrEP, which has shown to be equally effective in preventing HIV infection whilst touting an improved safety profile for renal and bone toxicity.
Descovy is currently available in all Dr Tan & Partners (DTAP clinics) in Singapore. It is a prescription only medication and must be prescribed by a doctor. Speak to our doctors for more information about Descovy and find out if a HIV-1 treatment that contains Descovy is right for you.
What is the difference between HIV PrEP and HIV PEP?
HIV PrEP should not be mistaken for HIV PEP (HIV Post Exposure Prophylaxis).
HIV PEP is for any individual who is at risk of HIV infection AFTER an HIV exposure, and requires taking anti-HIV medications for a month to reduce his or her chances of HIV infection. This must be started within 72 hours of a potentially risky exposure.
HIV PrEP must be started BEFORE any exposure, in the ways outlined above.
Both HIV PrEP and HIV PEP do not 100% reduce your chances of HIV infection, nor prevent you from being infected with other Sexually Transmitted Diseases (STDs) besides HIV.
HIV PEP as an HIV prevention strategy was first developed for healthcare workers, who are being exposed to contaminated blood or needlestick injuries. It has since expanded to other HIV high-risk activities such as sexual exposure and intravenous drug use.
Do I stop using Condoms when on HIV PrEP?
We do not recommend stopping condom use once you have started PrEP. Combining HIV PrEP and consistent condom use give you greater protection against HIV infection.
Also, HIV PrEP does not prevent you from other STD infections. Condom use can help prevent other STDs like syphilis, gonorrhea, and chlamydia.
What is HIV PrEP Medication?
Is a combination of anti-HIV medications. This was first approved for treatment of HIV infection in 2004, and was subsequently approved for use as regular PrEP in 2012. There have been some studies evaluating other drugs, but so far they have not shown the same effectiveness and tolerability.
What are the side effects of HIV PrEP?
Like any drugs, HIV PrEP can have some potential side effects.
A small number of people will experiences “start-up syndrome” like:
HIV PrEP may have a small risk of affecting your kidney and bone function. Hence, regular visits every 3 months with our doctors are essential to monitor for any complications.
Can I Stop HIV PrEP and How?
You can stop HIV PrEP at four weeks after you have had any high-risk HIV exposure, which should be followed by an HIV test and potentially other STD testing.
HIV PrEP should not be seen as the magic pill that provides a magic shield against HIV. It is just one more effective tool we have to reduce the risk of HIV infection.
Furthermore, HIV PrEP does not protect the user against other STDs. Therefore, even if you are on HIV PrEP, it is important to still to use a condom regularly, as well as get your regular STD screening & HIV Testing.
The HIV Pro-Viral DNA test can be used in specific situations where there are challenges to getting an accurate HIV diagnosis with other available HIV tests including HIV Antibody tests (3rd Generation HIV test), HIV Antibody and Antigen tests (4th Generation HIV test) as well as HIV RNA PCR test.
