HIV exposure can be a distressing experience, but fast action can significantly reduce the risk of infection. Post-Exposure Prophylaxis (PEP) is an emergency treatment that helps prevent HIV after possible exposure. If taken correctly within a critical 72-hour window, PEP can lower the chances of HIV transmission.
At He Medical Clinic, we provide confidential, professional, and effective HIV PEP treatment to individuals who may have been exposed to HIV. Here’s what you need to know about how it works, potential side effects, and its effectiveness.
What is HIV PEP and How Does It Work?
HIV PEP (Post-Exposure Prophylaxis) is a short-term antiretroviral treatment used to prevent HIV infection after potential exposure. The treatment consists of PEP HIV drugs, which work by stopping the virus from establishing itself in the body.
Key Points About HIV PEP:
- Must be started within 72 hours after potential exposure.
- Taken daily for 28 days for full effectiveness.
- Reduces the risk of HIV infection significantly when taken correctly.
- Not a substitute for regular HIV prevention methods like condoms or PrEP.
Who Needs HIV PEP?
PEP is recommended for anyone who may have been exposed to HIV through:
- Unprotected sex (including condom breakage or slippage).
- Sexual assault or non-consensual intercourse.
- Needle sharing or accidental needle injuries.
- Healthcare worker exposure to HIV-infected fluids.
PEP should be started as soon as possible—preferably within 2 hours of exposure, and no later than 72 hours. Delaying treatment reduces its effectiveness.
How Effective is HIV PEP?
HIV PEP is highly effective when taken correctly and within the recommended timeframe. Studies show that PEP can reduce HIV transmission by more than 80%. However, it is not 100% guaranteed.
HIV PEP Failure Cases: When Does PEP Not Work?
There are rare cases where HIV PEP failure occurs. Common reasons include:
- Starting PEP too late (beyond 72 hours).
- Skipping doses or not completing the 28-day course.
- Repeated high-risk exposure during the PEP treatment period.
- A strain of HIV that is resistant to PEP drugs.
To ensure maximum protection, it’s crucial to start PEP as early as possible and take the medication consistently as prescribed.
PEP HIV Drugs: What’s in the Treatment?
PEP consists of a combination of antiretroviral (ARV) drugs, usually:
- Tenofovir + Emtricitabine (TDF/FTC) – Also used for HIV PrEP (pre-exposure prophylaxis).
- Raltegravir or Dolutegravir – Helps prevent HIV replication in the body.
How Do These Drugs Work?
These PEP HIV drugs work together to block the virus from multiplying and establishing a long-term infection. They must be taken daily for 28 days to be effective.
Are There Side Effects of PEP HIV Drugs?
Most people tolerate PEP HIV drugs well, but some may experience mild side effects, including:
- Nausea and vomiting
- Fatigue and headaches
- Diarrhea or stomach discomfort
- Dizziness or difficulty sleeping
These side effects are usually temporary and subside after a few days. If they persist, consult your doctor at He Medical Clinic for guidance.
HIV PEP vs. HIV PrEP: What’s the Difference?
| Feature | HIV PEP (Post-Exposure Prophylaxis) | HIV PrEP (Pre-Exposure Prophylaxis) |
| Purpose | Prevents HIV after exposure | Prevents HIV before exposure |
| When to Take | Within 72 hours after exposure | Daily, before potential exposure |
| Duration | 28 days | Long-term, as needed |
| Who Should Use | People exposed to HIV unexpectedly | High-risk individuals (e.g., sex workers, those with HIV+ partners) |
| Effectiveness | Works if taken correctly & on time | Highly effective when taken daily |
If you are at continuous risk of HIV exposure, PrEP may be a better option. Consult He Medical Clinic for expert advice on whether HIV PEP or PrEP is right for you.

Frequently Asked Questions About HIV PEP
