Post-Exposure Prophylaxis (PEP) is a crucial emergency treatment used to prevent HIV infection after potential exposure. It involves a course of antiretroviral (ARV) medications, ideally started within 72 hours post-exposure. Prompt PEP treatment for HIV significantly reduces the risk of contracting the virus. This article explores the types of PEP available and their effectiveness.
What is PEP?
PEP is a short-term antiretroviral therapy for individuals potentially exposed to HIV, often prescribed in cases like:
- Occupational exposure (e.g., healthcare workers in contact with HIV-positive blood)
- Non-occupational exposure (e.g., unprotected sex, needle sharing, or sexual assault)
PEP works by preventing the virus from taking hold in the body. However, it must be started quickly—ideally within 72 hours of exposure. Once in the bloodstream, HIV can multiply rapidly, and PEP disrupts this replication process.
Types of PEP
There are two primary types of PEP: occupational PEP (oPEP) and non-occupational PEP (nPEP), each using a combination of antiretroviral drugs but prescribed under different circumstances.
- Occupational PEP (oPEP)
This PEP type is for those exposed to HIV in a workplace setting, such as healthcare professionals exposed to HIV-positive blood through needlestick injuries or similar incidents. The recommended treatment includes a combination of three antiretroviral drugs from two classes:- Emtricitabine (FTC) and Tenofovir Disoproxil Fumarate (TDF) together
- Along with dolutegravir (DTG) or raltegravir (RAL)
This drug combination effectively inhibits HIV replication, lowering the risk of infection. PEP HIV doctors in Delhi NCR provide essential treatment options for occupational HIV exposure, ensuring access to proper care.
- Non-Occupational PEP (nPEP)
nPEP is prescribed when someone has been exposed to HIV outside of work, such as:- Unprotected sex with someone who may be HIV-positive
- Sharing needles or other drug-use equipment
- Being a victim of sexual assault
The drug regimen for nPEP usually mirrors oPEP, using three medications from two drug classes, including:
-
- Emtricitabine (FTC) plus Tenofovir Disoproxil Fumarate (TDF)
- Either raltegravir (RAL) or dolutegravir (DTG)
Success with nPEP treatment depends on starting the medication quickly—ideally within hours of exposure—and following the full 28-day course. PEP treatment in Delhi is widely available in hospitals and clinics, making quick access to consultation crucial.
How PEP Works
PEP medications stop the virus from replicating by blocking the enzymes HIV needs to multiply. This prevents the virus from establishing an infection in the body. While PEP can be highly effective, success depends on early initiation and strict adherence. Studies indicate that PEP can reduce the risk of HIV by over 80% when used as directed, though it’s not 100% foolproof.
Who Should Consider PEP?
PEP should not replace other preventive measures like PrEP (Pre-Exposure Prophylaxis) or safe sex practices but is vital in emergencies. You may need PEP treatment for HIV if:
- You’ve had unprotected sex with a partner of positive or unknown HIV status
- You’ve shared needles or other drug-injection equipment
- You’ve experienced sexual assault
- You’ve been exposed to HIV in a healthcare setting
