PEP (Post Exposure Prophylaxis)

Post-Exposure Prophylaxis (PEP) is a preventive treatment regimen used to reduce the risk of contracting HIV (Human Immunodeficiency Virus) after a potential exposure to the virus. PEP is not a cure for HIV but is intended to be a preventive measure to stop the virus from establishing itself in the body.

Purpose of PEP:

PEP is employed in situations where there is a known or suspected risk of HIV infection following an exposure event. It is intended to prevent HIV from taking hold and spreading throughout the body. Common situations where PEP might be considered include:

Unprotected sexual intercourse:

If you've had unprotected vaginal, anal, or oral sex with a partner known to be HIV-positive, have an unknown HIV status, or in situations where there's a risk of exposure (e.g., condom breakage).

Needlestick injuries:

Healthcare workers or individuals who experience accidental needlestick injuries or other incidents that may involve contact with HIV-infected blood or bodily fluids.

Sexual assault:

PEP can be offered as part of medical care and support for survivors of sexual assault who may be at risk of HIV infection.

Sharing injection drug equipment:

If you've shared needles or injection drug equipment with someone who is HIV-positive or of unknown status.

How Pep Works?

PEP involves taking a combination of antiretroviral medications (similar to those used in the treatment of HIV) for a specified duration. These medications work by inhibiting the virus's ability to replicate and establish a permanent infection within the body. The goal is to prevent HIV from taking hold in the immune system.

When to Take PEP?

PEP should be initiated as soon as possible after potential exposure to HIV, ideally within hours but no later than 72 hours (3 days) after the exposure event. The effectiveness of PEP decreases with every passing hour, so early initiation is crucial.

How to Take pep:

Here are some important things to think about when taking PEP:

Prescription: PEP need a prescription because it is a prescription drug. To get a prescription, you must see a medical professional, like an emergency room doctor or an expert in infectious diseases.

Following the plan: Take the prescription drugs exactly as your doctor has instructed. Avoid skipping doses or stopping the medication too soon.

Full course completion: It is essential to complete the full 28-day course of PEP, even if you feel well or experience side effects. Stopping PEP prematurely can reduce its effectiveness.

Monitoring: Your healthcare provider may schedule follow-up appointments during and after PEP treatment to monitor your health and ensure that the treatment is working effectively.

Safe sex practices: While taking PEP, continue to practice safe sex by using condoms to reduce the risk of potential further exposure to HIV or other sexually transmitted infections.

Effectiveness of PEP

PEP significantly reduces the risk of HIV transmission when taken correctly and promptly after a potential exposure. However, it is not 100% effective, and there is still a possibility of infection, especially if PEP is not initiated promptly.

PEP is a critical tool in HIV prevention, particularly in situations where there is a known or suspected risk of exposure to the virus. If you believe you've been exposed to HIV, seek medical attention immediately to discuss the need for PEP with a healthcare professional. Additionally, consider regular HIV testing and preventive measures to reduce the risk of future exposure.
