HIV Post Exposure Prophylaxis

HIV Post Exposure Prophylaxis (PEP) is a medicine given to people who are at high risk of getting HIV. They are up to 99% effective in preventing a HIV infection.

You are a potential candidate for PEP if:

  • You have been exposed to potentially HIV infected body fluids
  • Your exposure was less than 72 hours ago

Factors that can increase the risk of HIV infection include:

  • Condom Break
  • Presence of Blood (e.g. Menses)
  • Presence of cuts
  • Presence of Ulcers
  • You are not circumcised

These medicines have to be started within 72 hours after possible infection/exposure.

They are taken twice a day for 1 month.

The side effects vary from person to person and also depend on which medicines are used.

Our clinic uses the medicines as recommended by the latest US CDC guidelines. These medicines have very limited side effects. From my experience, more than 9 out of 10 patients do not have any side effects at all. Those that do usually only have mild nausea.

These medicines cost $1928 at our clinic.  Click here for cost breakdown and details.

A repeat HIV test will be done once the medicines are finished (1 month). This HIV test will already be very accurate. In my personal experience, I feel that it is 100% accurate. We will also do another HIV test at 3 months post exposure (2 months after finishing PEP) as recommended by the guidelines.

      It is unlikely to pass on this way but since she is positive he should be doing testing anyway regardless of whether the condom was contaminated.

  2. Dr Tan,

    A friend of mine started PEP based on your doctor recommendation after consultation and negative HIV test. After 4 days on Truvada and Isentress, indeed not much of a side effect but a bit of bloaty stomach. However, today, he has some flu and mild sore throat. Is this just a side effect of the medication or just by chance that he caught these? Worried about too many things being read online about serconversion or something like that. Appreciate your advise whether for him to return for consultation now or just after 28 days. Thanks.

    • Sero-conversion symptoms usually come on about week 3 and are severe. They are never just a mild flu and sore throat. Click here for more info on HIV ARS. What is the more likely scenario is your friend just caught a cold which many people are down with this time of year in Singapore. His symptoms has nothing to do with the meds or with HIV ARS.
