Hello! As your medical assistant, I'd like to provide you with detailed information about post-exposure prophylaxis (PEP) for HIV. Please note that this information is based on the context provided, and for personalized medical advice, you should consult with a healthcare professional.
Post-Exposure Prophylaxis (PEP) for HIV:
PEP is a short-term antiretroviral treatment (ART) that can help prevent HIV infection after potential exposure. It must be started as soon as possible, ideally within hours, but no later than 72 hours after exposure.
There are two main types of PEP:
- Occupational PEP (OPEP): For healthcare workers or others who may have been exposed to HIV at work (e.g., needlestick injury).
- Non-occupational PEP (NPEP): For people who may have been exposed to HIV through sexual assault, unprotected sex, or other non-work-related activities.
When is PEP recommended?
- Occupational exposure: When there is a significant risk of HIV transmission, such as a needlestick injury involving a patient with HIV (CDC, 2018).
- Non-occupational exposure: When the risk of HIV transmission is high, such as sexual assault, unprotected sex with an HIV-positive person with a high viral load, or if the partner's HIV status is unknown (CDC, 2023).
PEP Regimen:
A typical PEP regimen includes a combination of three antiretroviral drugs, such as:
- Tenofovir (TDF or TAF) + Emtricitabine (FTC) + Raltegravir or Dolutegravir
Duration and Adherence:
- PEP should be taken for 28 days. It's crucial to take the medication exactly as prescribed, every day, at the same time (CDC, 2023).
- If you miss a dose, take it as soon as you remember, then take the next dose at the usual time. If it's almost time for your next dose, skip the missed dose and take the next dose as usual.
Side Effects and Monitoring:
- Common side effects may include nausea, headache, diarrhea, or fatigue. These usually lessen over time. Serious side effects are rare, but some drugs may affect your kidneys, bones, or liver (CDC, 2023).
- You will need regular blood tests to monitor for side effects and to check your HIV status.
Important Considerations:
- PEP is not a cure for HIV or a substitute for other prevention measures like condoms or pre-exposure prophylaxis (PrEP).
- It may not be effective if started more than 72 hours after exposure (CDC, 2023).
- If you have any allergies or medical conditions, inform your healthcare provider, as some PEP medications may not be suitable.
When to Seek Help:
If you think you may have been exposed to HIV, seek medical advice immediately. In some countries, PEP is available free of charge or at low cost through healthcare providers or sexual health clinics.
