Being informed and being able to communicate with partners freely about things like HIV, STIs, condom use, PEP, PrEP, HIV treatments, viral load in the strongest weapon we have to keep ourselves and our partners HIV & STI free. In this seemingly complex maze of HIV & STI prevention strategies it would be naïve to not look at the bigger picture when making informed decisions on how to best prevent HIV and STI transmission. So get reading and put yourself in the know!
PEP (Post-Exposure Prophylaxis)
PEP is a drug you can take immediately after a possible exposure to HIV to lessen the chances of infection?
PEP is a course of HIV medication which you can take if you have been at risk of HIV infection. The course of HIV medication lasts 28 days and, if taken within 72 hours of putting yourself at risk, may be able to prevent you from becoming infected with HIV. PEP stands for Post Exposure Prophylaxis – it is a form of protection (against HIV) that you can take after you have taken a risk or had a condom break on you.
Where to get PEP
You can get PEP at a GUM sexual health clinic or in Accident and Emergency. A&Es are especially important at weekends because most sexual health clinics will not be open. You must start PEP within 72 hours of putting yourself at risk of HIV, though the sooner you start PEP the more likely it is to be effective. Please note we cannot provide PEP at Pitstop Walk-in Clinics. For more information visit this site: https://www.gmfa.org.uk/pep
PrEP (Pre-Exposure Prophylaxis)
PrEP or pre exposure prophylaxis involves HIV negative people taking Truvada – (a drug currently used to treat people with HIV) as a method of helping to prevent HIV infection. Recent research has shown that if taken correctly, Truvada is up to 86% effective at reducing HIV risk.
PrEP is another layer of defence in preventing HIV transmission, it is particularly effective when used by guys, who regularly engage in unprotected anal sex or have frequent chemsex. PrEP will not prevent other STIs and should be included alongside condom usage as a part of the suite of HIV prevention strategies.
Information about the forthcoming PrEP IMPACT Trial (where 10,000 people in the UK will be given PrEP for free) and for information on where to go to express an interest in joining the trial can be found at:-
For further information on getting PrEP via private prescription, buying PrEP online and information about the medication itself visit these sites:
If you are accessing PrEP from somewhere else (other than a UK clinic) - for example if you are buying PrEP online, tell your sexual health clinician or your GP what you are planning and discuss the different ways you can take PrEP and how you can be monitored, whilst taking PrEP, to ensure that you are not sustaining any damage to your health.
TasP (Treatment as Prevention)
TasP or treatment as prevention, is a HIV prevention strategy which refers to someone who has been diagnosed HIV positive. If taken effectively HIV treatment can reduce the amount of the virus in a persons body. When there is so little HIV in a persons body it is referred to as an 'undetectable viral load' or 'undetectable' If someone has an undetectable viral load the risk of transmitting the HIV virus on to partners during sex is minimal.
It is indicated that taking effective HIV treatment is as effective as condom usage in reducing the chance of HIV transmission. It is important to note though that this is conditional and relies on other factors. The risk is minimal if:
- Neither partner has any other STIs
- The HIV positive partner has had a sustained undetectable viral load for more than 6 months
- and that their viral load is checked by a clinician every 3 - 4 months
Because of these variable factors, it is important that we view TasP as one part of the puzzle in the HIV prevention arsenal.
TasP will not prevent other STIs meaning that condom usage will still be required to offer the best protection for yourself and your partners, particularly for those having casual sex, those in new relationships and those in non monogamous relationships.
As a HIV prevention strategy in isolation of all other strategies (such as condoms) TasP requires incredibly high levels of trust between partners, high levels of communication and a certain vigilance on the HIV positive partners part to ensure adherence to HIV medications and regular viral load checks.
TasP is most certainly one of the game changers in HIV prevention. Like most HIV prevention strategies TasP will be a great option for some people but is an unlikely technique to suit all.
