HIV Post Exposure Prophylaxis (PEP)

HIV PEP or HIV Post Exposure Prophylaxis can reduce your risk of being infected with the Human Immunodeficiency Virus (HIV) after a potential exposure. HIV PEP is only effective up to 72 hours after HIV exposure. The ideal time to start HIV PEP is within 48 hours from exposure.

HIV PEP treatment may be prescribed to anyone with a high-risk HIV exposure and involves undergoing Antiretroviral (ARV) medications or antiretroviral therapy (ART) for a month. This is similar to HIV PrEP or HIV Pre-Exposure Prophylaxis, however, the difference is that HIV PrEP is taken daily before any HIV exposure.

HIV PEP only helps to reduce the risk of HIV infection, HIV PEP cannot protect you from being infected with other Sexually Transmitted Diseases (STDs)

Both HIV PEP & HIV PrEP are available in all our clinics.

Who needs HIV Post Exposure Prophylaxis (PEP)

HIV PEP should be used only in emergency situations and must be started within 72 hours after a recent possible High-risk exposure to HIV.

Factors Influencing Transmission Risks

Condoms & Circumcision

Compared to not using a condom and being uncircumcised, by using a condom and being circumcised can reduce HIV risk to certain extends. The condom creates a barrier that minimised infection. Some studies have found that the removal of foreskin, which is rich in Langerhan cells, can reduce the risk of contracting HIV by about 60%.

HIV Status of Partner

The Viral Load of HIV positive partner.

Sexually Transmitted Diseases (STDs)

The chances of HIV risk will increase when you or your partner are infected with other Sexually Transmitted Diseases (STDs).
