HIV and PrEP

Treatment for Prevention

The global fight against HIV is focusing on concepts of expanding testing programmes and Treatment as Prevention to combat the spread of this incurable disease.  Despite widespread knowledge of how to prevent acquisition of HIV there were 512 new diagnoses of HIV in Ireland in 2016. This is a 6% increase on 2016 numbers, and demonstrates a 60% increase over the last 5 years.

In 2016, two-thirds of new diagnoses (of known transmission route) were in the male or transgender person who has sex with men category. This is a marked increase on recent years, with data from 2014 and 2015 reporting approximately half of HIV diagnoses in this category. The use of antiretroviral therapy by at risk populations as pre-exposure prophylaxis (PrEP) is one of the tools that can help to prevent HIV transmission.

Pre-exposure prophylaxis means prevention before exposure. PrEP for HIV involves HIV negative people taking antiretroviral drugs before sex to reduce the risk of acquiring HIV. Currently approved PrEP is composed of the antiretroviral medications tenofovir disoproxil fumarate (TDF) and emtricitabine, combined in a single pill called Truvada™, on an ongoing basis before sex.  It does not protect a person from STI’s. Other precautions (condoms) need to be taken to prevent STI’s. 

PrEP is a highly effective way for HIV-negative people to prevent acquiring HIV by taking a daily pill. PrEP is recommended as a prevention option for people at substantial risk of HIV acquisition by the World Health Organization, the US Centers for Disease Control and UNAIDS.


Who needs PrEP?

PrEP is taken by someone who doesn’t have HIV but may be at risk of contracting HIV be-cause of sex practices.

How does PrEP work and are there side effects?

The PrEP drugs prevents HIV from entering  cells within the body and from replicating. This stops HIV from establishing itself and stops the person taking PrEP from becoming infected with HIV. Side effects like tiredness, nausea and headache can occur but the treatment is generally well tolerated.

What is the difference between PrEP and PEP?

PrEP is not the same as PEP (post-exposure prophylaxis) which is a combination of HIV/antiretroviral drugs to prevent HIV after a  potential exposure to the virus.

What research has been done on PrEP before?

Clinical trials studied the PrEP drug, Truvada™ and have shown that PrEP can be taken either daily (PROUD study) or taken before and after sex (event-driven) (IPERGAY study). Both of these studies showed  that PrEP dramatically reduced the risk of HIV infection by approximately 86%. Currently available data show that PrEP users are sufficiently protected against HIV if the drug is taken correctly. PrEP does not provide protection against other STI’s. Truvada™, in combination with safer sex prac-tices, was licenced for use as PrEP  in the United Sates in 2012 and in Europe in 2016.
