PrEP or pre-exposure prophylaxis involves HIV negative people taking HIV medication called Truvada as a method of helping to prevent HIV infection.
Recent research has shown that if taken correctly, Truvada is highly effective at preventing HIV infection.
It does not protect against any other STI, only HIV. You need to take other precautions in addition to PrEP to protect yourself from all other STIs. We recommend regular STI testing if you are on PrEP. You should have an HIV test every 3 month.
How to take PrEP
There are 2 ways of taking PrEP (based on 2 European studies):
- One tablet every 24 hours.
- Event-based dosing for a single sex act comprises two tablets 2–24 hours before sex, one tablet 24 hours (22–26 hours) after the first dose, and another tablet 48 hours (46–50 hours) after the first dose.
- This regimen is not recommended for vaginal sex.
Unfortunately, the cost of PrEP medicines is not currently covered by the NHS. However we can provide free advice and monitoring in any of our routine sexual health appointments.
NHS PrEP trial
The IMPACT study has now closed. Everyone who has been on IMPACT will be eligible for ongoing supplies of free PrEP from their respective clinic. This will continue until the NHS PrEP program has been set up. We need to see all IMPACT patients before Monday 12th October for their final trial visit so if we haven't seen you in the last 3 months please book online through the PrEP Self Assessment Form. You can pick up another 3 boxes of PrEP when you come in.
Non trial PrEP
- If you are taking PrEP bought online we can arrange ongoing monitoring at each clinic.
- We would recommend that we see you every 3 months and you have the following tests:
- HIV, Syphilis, Hepatitis B and Hepatitis C
- Chlamydia and Gonorrhoea testing
- A urine test to look for protein
- A blood test to monitor your kidneys every year
- We can also discuss any vaccines we can offer you and give you advice on how to take the medication and cope with any problems.
