PEP and PrEP in Bangkok

Living with HIV poses significant challenges, but with effective treatment and support, individuals can lead fulfilling lives. At MedEx, our commitment to comprehensive care includes offering Post-Exposure Prophylaxis (PEP) and Pre-Exposure Prophylaxis (PrEP) to help our patients stay healthy and prevent the transmission of HIV.

What is PEP?

Post-Exposure Prophylaxis (PEP) is a treatment aimed at preventing HIV after a possible exposure. It involves taking antiretroviral medications within 72 hours of potential exposure to the virus. PEP is highly effective when started promptly and taken correctly for the prescribed 28-day course.

When is PEP Used?

PEP is specifically for emergencies and not intended for regular use. Situations warranting PEP may include:

  • Unprotected sex with a partner of unknown HIV status.
  • Condom breakage during intercourse with an HIV-positive partner.
  • Sharing needles or other drug paraphernalia.
  • Incidents of sexual assault.

How Does PEP Work?

PEP functions by preventing the HIV virus from establishing a permanent infection within the body. Antiretroviral medications inhibit viral replication, allowing the immune system time to eradicate the virus before it spreads.

Understanding PEP and PrEP

What is PrEP?

Pre-Exposure Prophylaxis (PrEP) is a preventive measure for individuals who do not have HIV but are at high risk of contracting it. PrEP involves taking a daily pill that contains antiretroviral medications to reduce the risk of HIV infection. It's highly effective when taken as prescribed and combined with other prevention methods like condom use.

Who Should Consider PrEP?

PrEP is recommended for individuals at significant risk of HIV, including:

  • Men who have sex with men (MSM).
  • Heterosexual individuals with HIV-positive partners.
  • People who inject drugs.
  • Those with a recent bacterial STI, indicating high sexual activity without protection.

Steps to Take Before Starting PEP/PrEP

Consultation and Assessment

Before commencing PEP or PrEP, individuals must consult a healthcare professional to evaluate their eligibility. This includes discussing the treatment's benefits, risks, and potential side effects. PEP and PrEP are not meant for routine use. PEP is taken within 72 hours of potential HIV exposure, whereas PrEP is for those at high risk but not yet infected. Comprehensive lab tests, including HIV, VDRL, HBsAg, HCV, CBC, LFT (TP, Alb, Glo, TB, DB, ALT, AST), are essential before initiating PEP/PrEP. These tests ascertain the individual's health status and ability to tolerate the medication.

Side Effects and Safety

Both PEP and PrEP may exhibit side effects, such as nausea, fatigue, headaches, and digestive issues for PEP, and nausea, headaches, and weight loss for PrEP. Regular intake at the same time daily ensures effectiveness. Vigilant monitoring and reporting of any side effects to healthcare providers are crucial.

Follow-up and Monitoring

Lab tests should be repeated after one month of PEP/PrEP initiation to assess the body's response and check for adverse effects. Regular monitoring ensures the treatment's efficacy and the organs' healthy functioning. Early detection of issues allows for timely adjustments to the treatment plan.


Initiating PEP or PrEP signifies a crucial step in protecting oneself from HIV. Through comprehensive consultation, adherence to guidelines, and regular monitoring, individuals can ensure a safe and effective treatment journey. Follow-up tests after one month facilitate optimal outcomes. Prioritize your health and well-being by staying proactive
