On 1 December every year, we celebrate World Aids Day. What better time to discuss HIV prevention! Did you know that post-exposure prophylaxis (PEP) can prevent you from becoming infected with HIV after you have been exposed?

PEP is a medication that is taken soon after you have possibly been exposed to HIV to prevent HIV infection. It should only be used in emergency situations and can’t be used as a regular form of HIV prevention. You won’t be prescribed PEP if you are already HIV positive. You need to be HIV negative or unsure of your HIV status.

Possible exposures to HIV can take place in a number of different ways, such as:

  • Being sexually assaulted.
  • During sexual intercourse (for example, if the condom breaks).
  • Taking drugs and using dirty needles
  • Blood splashes for example when working with blood in laboratories or medical facilities.
  • Having an open wound and coming into direct contact with someone else’s blood.

PEP is most effective if you take it within 24 hours of the exposure but can be taken up to 72 hours after exposure. The sooner you take it the better – every hour counts!

PEP is taken for four weeks and ideally should be taken at the same time daily – it might not work if you miss doses. It is only available from a doctor, clinic, or hospital. If you think you have been exposed after hours, go to the emergency department at your nearest hospital, if there is one available and or seek medical assistance first thing the following morning. If you experience side effects like nausea, diarrhoea, or vomiting don’t just stop taking the medication! Speak to your healthcare provider who may prescribe medication to ease the symptoms. It is important to do HIV tests 3 and 6 months after the exposure to make sure that the treatment was successful.

In celebration of World Aids Day, this December, share your knowledge about PEP and HIV prevention with your friends and family – you never know whose life it could save!
