What is PrEP? A complete guide for Filipinos

The Philippines has one of the fastest-growing HIV epidemics in the Western Pacific. In that context, PrEP in the Philippines has become one of the most important tools for HIV prevention. Whether you searched for "what is PrEP" or "ano ang PrEP," this guide will walk you through everything you need to know, from how PrEP works, to where you can get it, and how much it costs. If you are looking for a PrEP clinic in the Philippines, you are in the right place.

What does PrEP stand for?

PrEP stands for Pre-Exposure Prophylaxis. Let's break that down:

• Pre-exposure means you take it before potential exposure to HIV.
• Prophylaxis means a treatment used to prevent a disease, not to cure it.

In simple terms, PrEP is a medication taken by people who do not have HIV in order to reduce their chances of getting it. It is not a vaccine, and it is not a cure. It is a preventive medicine that, when taken correctly, is highly effective at blocking HIV infection.

Ano ang PrEP?

Sa madaling salita, ang PrEP ay gamot na iniinom ng mga taong walang HIV upang maiwasan ang pagkakahawa. Hindi ito bakuna at hindi rin ito panlunas. Ito ay isang preventive medicine na, kapag tama ang pag-inom, ay napaka-epektibo sa paghadlang sa HIV.

How does PrEP work?

PrEP contains antiretroviral drugs, the same class of medications used to treat HIV. When you take PrEP consistently, the drug builds up in your body tissues, particularly in the blood, rectal tissue, and genital tissue.

If HIV enters your body through sexual contact or other exposure, the medication blocks the virus from replicating inside your cells. Without the ability to copy itself and establish a foothold, the virus cannot cause a permanent infection. Your immune system clears the blocked virus, and you remain HIV-negative.

The key word here is consistently. PrEP needs time to reach protective levels in your body:

• Receptive anal sex: About 7 days of daily dosing to reach full protection.
• Receptive vaginal sex and injection drug use: About 21 days of daily dosing to reach full protection.

That is why adherence, taking the medication as prescribed, is so important.

Types of PrEP

There are two main approaches to taking PrEP. Your healthcare provider can help you decide which method is right for your lifestyle.

Daily oral PrEP (TDF/FTC)

The most common form of PrEP available in the Philippines is a daily oral tablet containing tenofovir disoproxil fumarate (TDF) and emtricitabine (FTC), often sold under the brand name Truvada or its generic equivalents.

• Take one pill every day, at roughly the same time.
• Works for all types of sexual exposure and for people who inject drugs.
• This is the most studied form of PrEP and the one recommended by the World Health Organization (WHO).

On-demand PrEP (event-driven)

Also known as the 2-1-1 method, on-demand PrEP is an alternative dosing schedule studied primarily in men who have sex with men (MSM):

1. Take 2 pills between 2 and 24 hours before anticipated sexual activity.
2. Take 1 pill 24 hours after the first dose.
3. Take 1 pill 48 hours after the first dose.

On-demand PrEP has been shown to be effective for MSM in the IPERGAY study. However, it is not recommended for cisgender women, transgender individuals on feminizing hormones, or people who inject drugs, because there is not enough evidence of its effectiveness in those groups.

Always discuss with your healthcare provider which dosing approach suits your situation.

How effective is PrEP?

When taken as prescribed, PrEP is remarkably effective:

• Up to 99% effective at preventing HIV from sexual contact when taken daily.
• At least 74% effective at preventing HIV among people who inject drugs when taken daily.

The more consistently you take PrEP, the better it works. Skipping doses reduces its protective effect. Studies have consistently shown that among people with detectable drug levels in their blood, almost no HIV infections occur.

It is important to note that PrEP only protects against HIV. It does not protect against other sexually transmitted infections (STIs) like syphilis, gonorrhea, or chlamydia. Using condoms together with PrEP provides broader protection.

Who should consider taking PrEP?

PrEP may be right for you if you are HIV-negative and any of the following apply:

• You have a sexual partner who is living with HIV (especially if their viral load is not suppressed).
• You do not consistently use condoms during sex.
• You have been diagnosed with an STI in the past 6 months.
• You have multiple sexual partners.
• You engage in transactional sex (sex work).
• You inject drugs or share injection equipment.
• You have used post-exposure prophylaxis (PEP) more than once.
• You simply want an extra layer of protection and peace of mind.

PrEP is for anyone at risk. There is no judgment involved, just a practical health decision. If you are unsure whether PrEP is right for you, try using a community HIV risk screener to learn more about your personal risk level.

Side effects of PrEP

Most people tolerate PrEP well. Side effects, when they occur, are generally mild and tend to go away within the first few weeks. Common side effects include:

• Nausea (the most commonly reported side effect)
• Headache
• Fatigue
• Stomach discomfort or diarrhea
• Dizziness

These "start-up" side effects usually resolve within 2 to 4 weeks as your body adjusts.

In rare cases, long-term use of TDF-based PrEP can affect kidney function or bone mineral density. This is why regular monitoring through lab tests is an important part of being on PrEP. Your doctor will track your kidney health and overall well-being throughout treatment.

Serious side effects are uncommon. If you experience persistent or severe symptoms, talk to your healthcare provider. Do not stop taking PrEP without consulting your doctor first, as abruptly stopping may leave you unprotected.

Where to get PrEP in the Philippines

Access to PrEP in the Philippines has expanded significantly in recent years. Here are the main channels where you can access PrEP:

DOH treatment hubs

The Department of Health (DOH) operates treatment hubs across the country that provide free HIV testing, counseling, and PrEP services. These facilities are staffed by trained healthcare workers and are available in major cities like Metro Manila, Cebu, Davao, and others.

You can find DOH-accredited testing and treatment facilities through the Vitamigo facility directory.

Community-based organizations

Several community organizations provide PrEP access with a strong focus on safe, stigma-free care:

• LoveYourself operates community centers in Metro Manila (Anglo, Victoria, Lily, Welcome, and other branches) that offer free HIV testing, PrEP consultations, and ongoing support. They are known for their welcoming, non-judgmental environment.
• The Red Whistle provides education, testing, and referrals.
• Other local organizations across Visayas and Mindanao also provide PrEP access. Check the Vitamigo directory for locations near you.

TelePrEP and online services

For people who prefer more privacy or who live in areas with limited in-person services:

• SHIP TelePrEP (Sexual Health Information Program) offers teleconsultations with licensed physicians who can prescribe PrEP remotely. Medication can be picked up at partner pharmacies or delivered.
• Some community organizations have also begun offering virtual consultations, making PrEP more accessible outside of Metro Manila.

Private clinics

Private healthcare providers also prescribe PrEP. These may offer shorter wait times, extended hours, and a more personalized experience:

• PULSE Clinic in Makati offers comprehensive sexual health services, including PrEP, in a discreet, modern setting.
• Various infectious disease specialists and sexual health clinics in major cities can prescribe PrEP.

Browse the full list of HIV-related facilities on the Vitamigo directory to find a clinic near you.

How much does PrEP cost in the Philippines?

The cost of PrEP varies depending on where you access it:

| Source | Estimated cost | |---|---| | DOH treatment hubs | Free (government-subsidized) | | LoveYourself and other CBOs | Free or low-cost | | SHIP TelePrEP | Consultation fee + medication cost (varies) | | Private clinics | Consultation fee + medication, typically PHP 1,500 to PHP 5,000+ per month depending on brand | | Generic TDF/FTC | Can be found for around PHP 1,000 to PHP 2,500 per month |

If cost is a barrier, start with government-funded programs or community organizations. Many of them provide PrEP at no charge, including free HIV testing, including the required lab tests and follow-up consultations.

Regular monitoring while on PrEP

PrEP is not a "take it and forget it" medication. Regular follow-up with your healthcare provider is essential. Here is what to expect:

• HIV test every 3 months: You must confirm that you are still HIV-negative before continuing PrEP. Taking PrEP while unknowingly HIV-positive can lead to drug resistance.
• Kidney function tests: Creatinine and estimated glomerular filtration rate (eGFR) should be checked at baseline and periodically (typically every 6 to 12 months) to ensure your kidneys are functioning well.
• STI screening: Regular testing for syphilis, gonorrhea, chlamydia, and hepatitis is recommended since PrEP does not protect against these infections.
• Adherence check-in: Your provider will discuss how consistently you are taking the medication and whether any adjustments are needed.

These check-ups are a normal part of PrEP care and are not something to worry about. Think of them as routine maintenance for your health.

PrEP vs. PEP: what is the difference?

People often confuse PrEP and PEP. While they both use antiretroviral medications, they serve different purposes:

| | PrEP | PEP | |---|---|---| | When you take it | Before potential exposure | After potential exposure | | Purpose | Ongoing prevention | Emergency prevention | | Duration | Taken continuously (daily or on-demand) | 28-day course | | Time window | Planned in advance | Must start within 72 hours of exposure | | Ideal for | People at ongoing risk | One-time or unexpected exposure |

If you had a potential exposure to HIV and are not on PrEP, seek PEP as soon as possible, ideally within 24 hours and no later than 72 hours after the event. You can find PEP providers through the Vitamigo directory.

Frequently asked questions

Does PrEP have long-term side effects? For most people, PrEP is safe for long-term use. The most closely monitored long-term concern is kidney function, which is why regular lab work is part of PrEP care. Studies with over a decade of follow-up data have not identified major long-term health risks for most users. Your doctor will help determine whether PrEP remains appropriate for you over time.

Can I stop and restart PrEP? Yes. PrEP is flexible. If your risk level changes, such as entering a monogamous relationship where both partners are tested, you can discuss stopping with your doctor. If your circumstances change again, you can restart. Remember that it takes 7 days of daily dosing (for receptive anal sex) or 21 days (for vaginal sex) to reach full protection after restarting.

Will PrEP show up on my medical records or insurance? If you access PrEP through a public DOH facility or community organization, your information is treated as confidential under Republic Act No. 11166, the Philippine HIV/AIDS Policy Act. This law protects the confidentiality of HIV-related medical records. If privacy is a major concern, community-based organizations like LoveYourself often provide the most discreet experience.

Is PrEP only for men who have sex with men (MSM)? No. PrEP is for anyone at risk of HIV, regardless of gender, sexual orientation, or identity. While MSM are disproportionately affected by HIV in the Philippines, PrEP is equally recommended for cisgender women, transgender individuals, people who inject drugs, and anyone else with risk factors. HIV prevention is for everyone.

Do I still need to use condoms if I am on PrEP? PrEP is highly effective against HIV, but it does not protect against other STIs. Using condoms along with PrEP provides the most comprehensive protection. That said, PrEP alone is still a powerful prevention tool, and the decision to use additional methods is a personal one best discussed with your healthcare provider.

Take the next step

You do not need to navigate this alone. If you are considering PrEP, the most important first step is to get an HIV test and have a conversation with a healthcare provider who understands PrEP.

• Browse clinics and facilities on the Vitamigo facility directory to find PrEP providers near you.
• Check your risk level with a community screener if you are unsure whether PrEP is right for you.

Taking charge of your health is an act of self-care, never something to be ashamed of.
