Preventing STIs

Protect Yourself

Condoms work really well in stopping most STIs from being passed from an infected partner to another. Although they are not 100% guaranteed, when used properly condoms are extremely effective. Use a condom every time you have vaginal, anal or oral sex.

Post Exposure Prophylaxis against HIV (PEP or PEPSE)

Post-exposure Prophylaxis (PEP or PEPSE) is medication to help reduce HIV transmission after the virus has entered the body. It is a course of drugs that is taken after sex where there has been a higher risk of exposure.

If you are concerned you might have been exposed to HIV (had unprotected sex with someone whose HIV status you do not know, or know to be positive, or shared injecting equipment), you may be eligible for PEP. Post-exposure Prophylaxis (PEP or PEPSE) is medication you can take to help reduce the chance of HIV transmission. It is a course of medication that is taken after unprotected sex where there has been a higher risk of exposure. PEP or PEPSE should be taken as soon as possible after sex, and definitely within 72 hours. The earlier it is started the more likely it is to work. You will need to have an assessment with a doctor or nurse before you are prescribed this medication.

In hours, attend one of our clinics or after hours attend your nearest A&E department.

DoxyPEP/DPEP (doxycycline post-exposure prophylaxis)

DoxyPEP is taken as one 200 mg dose after condomless sex. It is best to take it within 24 hours, but it still works up to 72 hours later. Only take one dose every 24 hours, no matter how many times you had sex during that time. If you have a lot of sex over a few days, you can just take one dose at the end of that 72-hour period. 

DoxyPEP may be recommended for:

  • Gay, bisexual and other men who have sex with men (MSM) and transgender women
  • People who have increased risk of acquiring Syphilis eg having a diagnosis of a bacterial STI in the last 12 months
  • People with recent history of multiple new sexual partners
  • People in sexual networks or communities with high rates of STI’s ie groupsex, chemsex

We are able to offer DoxyPEP to eligible people attending clinic depending on individual risks and benefits. Please discuss this with us when you call 0300 300 2016 or attend for an appointment.
