What Is Daily PrEP? How to Take It for Maximum HIV Protection
Today, HIV prevention is no longer limited to condom use alone. Modern medicine now offers a proven and highly effective option called PrEP (Pre-Exposure Prophylaxis) — a preventive medication that significantly reduces the risk of HIV infection.
One of the most popular forms is Daily PrEP, a once-daily pill designed to maintain protective drug levels in the body at all times. It’s especially suitable for individuals who have frequent sexual activity or are at higher risk of HIV exposure.
This article will guide you through everything you need to know about Daily PrEP — how it works, how to start, its benefits, possible side effects, and expert recommendations from Bangkok Safe Clinic to help you make an informed and confident decision.
What is Daily PrEP
Daily PrEP is a preventive approach against HIV infection that involves taking one antiretroviral pill every day. This helps maintain a consistent level of medication in the bloodstream, allowing the body to block the virus if exposure occurs.
It is recommended for individuals who have frequent sexual activity or are at higher risk of HIV exposure. When taken correctly and consistently, Daily PrEP can reduce the risk of HIV transmission by more than 99%, according to the World Health Organization (WHO) and the U.S. Centers for Disease Control and Prevention (CDC).
Most Daily PrEP regimens contain Tenofovir disoproxil fumarate (TDF) and Emtricitabine (FTC), following internationally approved guidelines. It should always be used under medical supervision to ensure safety and optimal effectiveness in preventing HIV infection.
How Is Daily PrEP Different from On-Demand and Injectable PrEP
There are three main types of PrEP for HIV prevention: Daily PrEP, On-Demand PrEP, and Injectable PrEP.
All provide highly effective protection, but they differ in usage and suitability depending on individual lifestyle.
Daily PrEP requires taking one pill every day to maintain consistent protection — ideal for people with frequent sexual activity or unpredictable exposure.
On-Demand PrEP is taken only before and after sexual activity, following a specific dosing schedule. It suits individuals who have sex infrequently or can plan in advance.
Injectable PrEP involves receiving an intramuscular injection every two months. It eliminates the need for daily pills and reduces adherence issues. The main drug used is Cabotegravir (CAB-LA), approved by the World Health Organization (WHO) and now available in select clinics, including some in Thailand.
Each method offers over 99% protection when used correctly. The best choice depends on individual habits, convenience, and consultation with a qualified healthcare provider.
Who Is Daily PrEP Suitable For
Daily PrEP is recommended for people at higher risk of HIV exposure, including men who have sex with men (MSM), individuals with multiple partners, people with an HIV-positive partner, and sex workers.
It’s ideal for those who have frequent or unplanned sexual activity. Taking one pill daily ensures consistent protection and peace of mind without the need to plan ahead.
This regimen also suits individuals seeking long-term HIV prevention, especially those who engage in unprotected sex or are unsure of their partner’s HIV status. However, it should always be used under medical guidance to ensure that the dosage and monitoring align with personal health conditions and risk levels.
How to Start Using Daily PrEP
Starting Daily PrEP should always be done under medical supervision to ensure safety and effectiveness. Proper preparation helps maintain optimal protection against HIV.
- 1Get a health check before starting. A doctor will perform blood tests to confirm that you are HIV-negative and to check kidney and liver function, as well as screen for other sexually transmitted infections (STIs).
- Consult a healthcare professional Your doctor will help determine whether Daily PrEP, On-Demand PrEP, or Injectable PrEP best fits your lifestyle and level of risk.
- Take one pill every day. It’s best to take the medication at the same time each day and start at least seven days before having sex without a condom to ensure sufficient drug levels in your body.
- Follow up every 3 months Regular blood tests are recommended every three months to monitor your health, check for side effects, and continue receiving medication safely under medical guidance.
How to Take Daily PrEP Effectively
The key to making Daily PrEP work effectively is consistency and proper timing. Taking the pill correctly ensures stable drug levels in your bloodstream, which maximizes HIV protection.
Take one pill every day at the same time — before or after meals is fine — to maintain good absorption. For optimal protection, start taking PrEP at least 7 days before unprotected sex
If you miss a dose, take it as soon as you remember. If it’s been more than 12 hours, skip the missed pill and take the next dose as usual. Never take two pills in one day. If you’ve stopped taking PrEP for several days, consult your doctor before restarting to ensure your body is ready and your protection is effective.
Staying consistent with Daily PrEP and attending check-ups every three months will help maintain maximum HIV protection and minimize potential side effects.
Effectiveness of Daily PrEP
Daily PrEP is one of the most effective methods for preventing HIV infection. According to studies by the World Health Organization (WHO) and the U.S. Centers for Disease Control and Prevention (CDC), it can reduce the risk of contracting HIV by more than 99% when taken consistently and correctly.
PrEP works by blocking the HIV virus from replicating in the body if exposure occurs, preventing infection from being established. However, PrEP protects only against HIV — it does not prevent other sexually transmitted infections (STIs) such as gonorrhea, syphilis, or HPV.
While its effectiveness is extremely high, consistent daily use and regular medical check-ups are crucial. Combining PrEP with condom use provides the strongest overall protection against HIV and other STIs.
Benefits of Daily PrEP
Daily PrEP makes HIV prevention simple and consistent. It’s ideal for people who want peace of mind in their sexual relationships without worrying about planning ahead.
One of the biggest advantages is continuous protection — taking one pill a day maintains stable drug levels in the body, ready to block the virus upon exposure. It also helps reduce anxiety and fear of HIV, especially for those who are sexually active or have multiple partners.
Daily PrEP can also strengthen confidence in long-term relationships, particularly for serodiscordant couples, where one partner is HIV-positive. With proper use and regular medical check-ups, both partners can live safely and confidently.
Another advantage is accessibility — several approved brands are now available in Thailand, all regulated by the Thai FDA. This makes Daily PrEP a safe, evidence-based, and globally trusted prevention option.
Precautions and Side Effects of Daily PrEP
While Daily PrEP is highly effective for HIV prevention, it’s important to use it correctly and under medical supervision to ensure safety.
Before starting, individuals should have an HIV test and assess kidney and liver function, as the medication may affect these systems in some people. Those with pre-existing kidney conditions may require an alternative regimen or dosage adjustment by their doctor.
Common side effects in the first few days include mild nausea, headache, or fatigue — these usually subside once the body adjusts. If you experience severe abdominal pain, unusual urination, or persistent discomfort, stop the medication and consult a healthcare provider immediately.
Regular check-ups every three months are essential for monitoring overall health, confirming HIV-negative status, and ensuring that PrEP remains safe and effective for long-term use.
User Reviews and Doctors’ Insights
Most people who use Daily PrEP report a positive change in their lives — feeling more confident and less anxious about HIV. Knowing they’re protected and regularly monitored by healthcare professionals gives them a sense of control and reassurance.
From a medical perspective, infectious disease specialists emphasize that consistent, doctor-supervised use of Daily PrEP is one of the most evidence-based strategies for HIV prevention. It’s especially effective among men who have sex with men (MSM), serodiscordant couples, and those who engage in unprotected sex.
Doctors also remind users that PrEP should not replace condoms but rather serve as an additional layer of protection. Combined with regular check-ups and medical guidance, Daily PrEP allows people to live their sexual and personal lives with greater confidence and safety.
