    What is PEP?

    PEP, or Post-Exposure Prophylaxis, is an emergency HIV prevention treatment. It involves taking antiretroviral medication after potential exposure to HIV—such as through unprotected sex or sharing needles.

    PEP must be started within 72 hours after potential exposure.

    When Should You Consider PEP?

    If you believe you've recently been at risk of HIV infection—such as:

    • Having unprotected sex or experiencing condom failure
    • Sharing needles or injection equipment
    • Being sexually assaulted

    You should seek medical attention immediately, ideally within 72 hours (3 days). The sooner PEP is started, the more effective it is—every hour counts. If prescribed, PEP must be taken once daily for 28 consecutive days.

    PEP Is for Emergency Use Only

    PEP is intended for emergency situations after potential exposure to HIV. It is not meant for daily or routine use.

    • PEP is not a substitute for condoms or PrEP (Pre-Exposure Prophylaxis).
    • It is not suitable for people with frequent or ongoing risk of HIV exposure.
    • If you are regularly at risk, you should speak with a healthcare provider about using PrEP, which is more appropriate for long-term prevention.

    How Much Does PEP Cost?

    PEP is a prescription-only medication classified as a high-risk drug. It must be prescribed by a qualified healthcare provider after an HIV risk assessment and a blood test. It is not available over the counter or through online retailers.

    The medication regimen prescribed may vary depending on the clinic and the doctor’s evaluation. Treatment costs typically start at around 1,500 THB, but can vary depending on the drug combination used.

    It's recommended to call ahead for details. You can find nearby clinics or hospitals that provide HIV testing and PEP services for urgent care here.
