You’ve likely seen the term “PrEP” on social media, dating apps, or heard it from friends. But what is it, and how does it work if you’re living in Bali? PrEP stands for Pre-Exposure Prophylaxis. It is a daily pill for preventing HIV. This is a no-nonsense, practical guide on what PrEP is, who it’s for, and how to get it safely in Bali.

What is PrEP (And What It Isn’t)?
What It Is
PrEP is a daily medication (like Truvada or Descovy) taken by people who are HIV-negative to prevent getting HIV. When taken as prescribed, PrEP is over 99% effective at preventing HIV transmission through sex.
What It Isn’t
It’s important to be clear on what PrEP doesn’t do. It is NOT a vaccine, and it is NOT a “morning-after” pill—that is PEP (Post-Exposure Prophylaxis), which is an emergency treatment after a potential exposure. Furthermore, PrEP does NOT protect against other STDs like Chlamydia, Gonorrhea, or Syphilis.
Who Should Consider PrEP?
A healthcare professional can help you decide if PrEP is right for you. It is recommended for people who are HIV-negative and at high risk for HIV, based on risk (risiko), not identity (identitas).
This includes if you:
- Have had anal or vaginal sex in the past 6 months and…
- Have a sexual partner with HIV (especially if their viral load is unknown or detectable).
- Have not consistently used a condom.
- Have been diagnosed with another STD in the past 6 months.
How to Get PrEP Safely in Bali: The 3-Step Medical Process
Starting PrEP is a serious medical decision that requires professional supervision.
Step 1: The Consultation & HIV Test
You MUST be confirmed HIV-negative before starting PrEP. A doctor must screen you first. Taking PrEP if you are already HIV-positive is dangerous and can cause the virus to become resistant to medication.
Step 2: The Full Screening (Blood & Urine)
Because PrEP only protects against HIV, a responsible doctor will also require a full STD screening (including Hepatitis B/C and Syphilis) and a baseline blood test to check your kidney function.
Step 3: The Prescription & Ongoing Follow-Up
If you are cleared, the doctor will provide a prescription. PrEP is an ongoing medical commitment. You must return every 3 months for repeat HIV/STD tests and medical monitoring to get your next prescription.

PrEP Myths vs. Facts (Bali Edition)
A common myth is that you can buy PrEP over-the-counter at an apotek in Bali. This is incorrect and dangerous. PrEP requires a doctor’s prescription and mandatory lab testing. Anyone providing it without testing is putting your health at serious risk.
Another myth is that you can stop using condoms while on PrEP. This is a dangerous misconception. PrEP does nothing to stop Chlamydia, Gonorrhea, or Syphilis. Condoms are still essential for protecting against all other STDs.
Conclusion
PrEP is a powerful and revolutionary tool for HIV prevention, but it’s a serious medical commitment, not a casual “vitamin”. It requires a professional, confidential, and ongoing relationship with a doctor to ensure it is effective and, most importantly, safe.
