HIV post-exposure prophylaxis (PEP) is a short term preventive treatment for HIV infection after potential exposure to the virus.
It’s intended for emergency situations, it is not meant for regular use by people who may be exposed to HIV frequently.
PEP should be initiated as soon as possible, ideally within 72 hours (3 days) after exposure.
People who present after 72hrs of exposure can be provided with other appropriate services like counselling and support.
PEP consists of a 28-day course of antiretroviral medications, which are drugs used to treat HIV. These medications work by preventing the virus from replicating and spreading throughout the body.
An ARV regimen with preferably three drugs should be offered e. g
<15years ABC+3TC+DTG
>15years TDF+3TC/FTC+DTG
In Kenya, PEP is normally offered at most Comprehensive Care Clinics at no fee.
It does not protect against other sexually transmitted infections.
PEP is typically recommended in the following situations:
1. Occupational exposure: Healthcare workers or others who may have been exposed to HIV-infected blood or bodily fluids through needle sticks or other accidents in healthcare settings.
2. Non-occupational exposure: Individuals who may have been exposed to HIV through sexual activity, injection drug use, or other activities outside of a healthcare setting.
Who is eligible for PEP?
A HIV negative individual who has been exposed to HIV
An individual who has been exposed within 72hrs
A person who has been exposed to bodily fluids which pose a significant risk
If an individual is already HIV positive or if the exposure to bodily fluids does not pose a significant risk they do not need PEP.
How to take PEP
- It should be started as soon as possible after but not later than 72hrs
- It should be taken daily without fail, one tablet daily for 28days
- If you miss a dose and remember in less than 24hrs, take the next one as soon as you remember
- If you miss more than 48hrs of PEP, it will be discontinued
- There should be follow up after one has started taking PEP
It’s essential to understand that PEP is not 100% effective and should not be considered a substitute for other preventive measures such as practicing safe sex and using clean needles for injection drug use. Additionally, PEP should not be seen as a fallback strategy for unprotected sex; it’s an emergency measure.
What are the side effects of PEP?
- Nausea and vomiting
- Headache
- An upset stomach
- Diarrhea
- Fatigue and tiredness
The above side effects are only short term thus they should not cause any worry, however if they become persistent, you can consult a health care provider.
