I take PrEP to avoid HIV. That's what works for me.


What is PrEP?

PrEP is the use of medication that HIV-negative individuals take to prevent them from becoming HIV-positive. PrEP is appropriate for anyone at risk of HIV infection including gay, bisexual and trans guys who have condomless sex, people who are in sero-discordant relationships or engage in intravenous drug use.

How does PrEP work?

PrEP prevents HIV by creating a biological barrier against HIV in your body. When taken as prescribed PrEP is a highly effective way of preventing HIV.

Does PrEP have any side effects?

Research has shown that PrEP can negatively impact on some people’s kidneys and/or their bone density. When you are prescribed PrEP, your doctor will regularly check that you are not experiencing these side effects.

Other side effects can include nausea and headaches; however these usually subside within a week or so. If you experience side effects that do not resolve quickly, or are a concern to you then it is important to talk to your doctor. You can find out more about PrEP by watching the video below.

PrEP and other STIs

Remember, PrEP is only one way to prevent HIV and that it does not provide any protection against other STIs. If you decide to stop using condoms or reduce your condom use, then it is important to keep up regular sexual health testing so that if you do get an STI you can easily have it diagnosed and treated.

What is On-Demand PrEP?

Whilst daily PrEP is the most recommended method for taking PrEP, there is another dosing option that can still protect you against HIV, known as On-Demand. On-Demand PrEP is different to regular PrEP, it has a different dosing schedule.

On-Demand PrEP involves:

  • Taking two pills 2-24 hours before sex; then
  • Taking one more pill 24 hours after the first double dose; then
  • Taking one final pill 24 hours after the second dose

On-Demand PrEP is different to regular PrEP, it has a different dosing schedule

It is really important to remember your dosing times, and if you have more sex on a day during the time period that you are using On-Demand PrEP, then you need to keep taking a pill each day, and then for two days after the last time you have sex.

If planned and taken appropriately then this dosing strategy can protect you against HIV, however On-Demand PrEP has not been proven to work for vaginal or front-hole sex. It is only recommended for anal sex.

To find out more about what is involved in On-Demand PrEP and whether it may work for you, please watch the video below.
