PEP (Emergency PEP) - Emergency Solutions to Prevent HIV Transmission


 

Key Points

  • PEP involves taking a 28-day course of anti-HIV drugs, after possible exposure to HIV.
  • Doctors will assess your risk of HIV infection before prescribing PEP.
  • We recommend the ned medication called KOCITAF
  • PEP is available from sexual health clinics and accident & emergency departments.

Condom Break? Get PEP in Bangkok at PULSE Clinic! If you need emergency PEP after a condom failure, visit PULSE Clinic. We are open 7 days a week, including weekdays and weekends, for your convenience! If you have had a high-risk exposure to HIV in the last 72 hours, it's crucial to begin HIV PEP (Post-Exposure Prophylaxis) as soon as possible. For optimal effectiveness, start PEP within 24 hours after potential exposure.

The sooner you initiate PEP, the better your chances of preventing HIV infection. Decades of research and experience demonstrate that PEP can significantly reduce the risk of HIV transmission.

Factors that can increase the risk of HIV infection and you are a potential candidate for PEP due to:

  • The partner is known to be HIV positive AND is not on treatment.
  • Anal sex with penetration without condom
  • Vaginal sex without condom
  • Condom break
  • Presence of blood
  • Presence of cuts or ulcers
  • You are not circumcised
  • You have been exposed to potentially HIV infected body fluids
  • Your exposure was less then 72 hours ago
  • Partner of unknown HIV status who belong to higher risk HIV group (e.g. MSM or from africa or S.E.Asia)
  • They penetrated you (Their penis, your arse) AND you don't know for sure whether they have HIV or not.

 

Missed the 72-Hour Window for HIV PEP? Seek Medical Advice!


If you cannot access HIV PEP (Post-Exposure Prophylaxis) within 72 hours, even if it's been 5-7 days since potential exposure, it's still essential to consult a healthcare professional about your options. You may be eligible for a 3-drug combination of antiretroviral medications to begin early treatment, which can help minimize damage to your immune system in case you have contracted HIV. Taking prompt action can be crucial for your health.

How Does PEP Work to Prevent HIV?


After potential exposure to HIV, it takes a few days for the virus to establish itself in the body. Once established, HIV can remain for life. However, starting PEP (Post-Exposure Prophylaxis) promptly can be crucial. Anti-HIV medications in PEP prevent the existing virus from replicating, allowing it to die out before it can multiply.

These PEP drugs support the body's immune system in halting the replication of HIV within infected cells. As a result, the initially infected cells can die off naturally within a short time, preventing further HIV production.

 

How Effective is PEP in HIV Prevention?


PEP is not a ‘cure’ for HIV. While PEP may prevent HIV from entering cells in the body and stop someone from becoming infected, it isn’t 100% effective. However, there have been very few reports of HIV infection after using PEP.

 

 

But if the HIV is already in the body, isn't it too late?


Not if you act quickly! After exposure, HIV can enter the bloodstream but takes time to establish itself permanently in the body. If a person exposed to HIV seeks PEP (Post-Exposure Prophylaxis) within 72 hours, they have a strong chance of preventing the virus from becoming established.

 

So, if I take PEP I won't become HIV positive?


Research indicates that taking PEP makes infection with HIV a lot less likely. But PEP doesn’t work every time. Some people who take it still end up with HIV afterwards. When people taking PEP have acquired HIV, it can fail because:

  • Some people might not starting PEP quickly enough
  • The person doesn’t or isn’t able to take PEP as prescribed (every day for a month)
  • Missing doses of PEP or not finishing the 28-day course
  • Some anti-HIV drugs don’t work against some strains of HIV (HIV drug resistant, although this is rare)*
  • The initial viral load (the amount of HIV) in the body was too great for the drugs to be effective**
  • Having unprotected sex or sharing needles, with further exposure to HIV, while taking PEP.

However, the sooner PEP treatment is begun after exposure to the virus, the more likely it is to work.

Which HIV PEP Medications Are Available at Our Clinic?


We use the latest gold standard PEP medicines with fewer side effects and better HIV prevention which will be taken for 28 days.

For adults: Tenofovir combined with either Tenofovir (TDF) and emtricitabine (FTC) as preferred backbone drugs and these are also the preferred drugs for treating HIV.

The recommended third drug, which is also recommended by WHO and CDC as a preferred drug for HIV treatment, will be chosen by your doctor.

There are some of our clients who do not understand when our doctors try to explain about HIV drug resistant. If you are unlucky and being exposed to such HIV, the classic PEP medications are not able to help you. That's why American CDC suggested on their PEP treatment guidelines that we should use a higher class of drugs that is less likely to be resisted by the HIV drug resistant type. These higher class medications are available at our clinics and they are costly. Much more expensive than the classic PEP medications generally used in low income countries. When our doctors prescribe this higher class PEP medications it is because they evaluate that your risk is very high and they are trying to keep the standard as high as American Center of Disease Control Guidelines for PEP treatment.

 

What Additional Steps Should You Take After Possible HIV Exposure?


Your doctor may recommend treatment as prevention for potential gonorrhea, chlamydia, or syphilis following unprotected sex or a sexual incident. We suggest the PCR multiplex test, which detects 28 infection that cause STD, available at PULSE Clinic.

 

You Might not Need PEP If...


  • You are confident that your partner is HIV-negative.
  • Your partner is HIV-positive and on successful treatment, maintaining an 'undetectable viral load.'
  • Human bites.
  • Contact with another person’s semen in your eye.

What Questions Will the Doctor Ask During Your HIV Evaluation?


The doctor will assess your risk of HIV exposure before initiating treatment. Expect questions about the circumstances surrounding your potential exposure, including the type of sexual or injecting activity involved and whether your partner may be HIV-positive.

Specific inquiries may include:

  • Do you know if the person has HIV? If so, do you know if they maintain an undetectable viral load?
  • What type of sexual activity occurred (e.g., anal, vaginal, or oral sex)?
  • Did you penetrate or were you penetrated during the encounter?
  • Did either of you ejaculate inside the other?
  • Are there any other concerns you would like to discuss?

These questions help determine the most appropriate course of action for your health.

It is important to be honest and accurate in providing this information – We are there to help you, not to judge you.

The information you provide will help us evaluate the seriousness of your situation. It’s important to note that the risk of contracting HIV through oral sex is extremely low. PEP (Post-Exposure Prophylaxis) is generally not recommended after potential exposure to HIV via oral sex. The only exception is if receptive oral sex was performed by a partner known to be HIV-positive, particularly if the receptive partner has cuts or lesions, such as ulcers, in their mouth.

 

At PULSE CLINIC (in every branch throughout Asia), we have seen this more than 4,000 times before; you’re not the first and you won’t be the last. The doctor won’t judge; they will be very helpful and make you feel at ease. If you think you’re at risk and need PEP, contact us.

What Are the Side Effects of HIV PEP?


With the new PEP (Post-Exposure Prophylaxis) medications we use, side effects are very rare—fewer than 1 in 100 patients experience any adverse effects.

Common Side Effects
While side effects occur in less than 1% of patients, some of the most commonly reported include:

  • Nausea
  • Diarrhea
  • Fatigue

Less Common Side Effects Rash and fever are uncommon side effects, occurring in less than 0.1% of cases. A study from Australia found that patients taking raltegravir and emtricitabine/tenofovir disoproxil as PEP reported the following side effects:

  • Fatigue (37%)
  • Diarrhea (25%)
  • Nausea (24%)
  • Flatulence (24%)
  • Abdominal cramps (21%)
  • Bloating (16%)
  • Headache (15%)
  • Vivid dreams (15%)
  • Depression (10%)
  • Increased thirst (10%)

It's important to note that the PEP drugs used today are less likely to cause side effects compared to those used in the past. Patients generally find them more tolerable, making it easier to complete the 28-day treatment course."

How Can I Remember to Take My PEP?


Staying consistent with your PEP (Post-Exposure Prophylaxis) medication is crucial for effectiveness. Here are some tips to help you remember to take your PEP daily for the entire month:

  • Set Daily Reminders: Use your mobile phone to set alarms or reminders for your medication schedule.
  • Establish a Routine: Take your PEP at the same time every day, such as after breakfast or dinner.
  • Use Visual Cues: Keep your PEP medications near items you use daily, like your toothbrush, to serve as a reminder.
  • Link to Daily Habits: Take your medications when you brush your teeth and place them next to your toothbrush to ensure you notice them.
  • Create Discreet Reminders: Attach a post-it note with the letter ‘P’ on your fridge or noticeboard as a subtle reminder to take your medication.
  • Be Prepared for Nights Out: Carry enough PEP with you if you’re planning a big night out, just in case you don’t make it home.
  • Involve a Friend: Ask a trusted friend to remind you to take your medications.

 

Taking Other Drugs While on PEP


It's essential to be cautious when taking other medications while on PEP. PEP can interact with prescription drugs, supplements, and vitamins, potentially altering their effectiveness. Additionally, using recreational drugs during PEP can be risky and may lead to severe side effects when combined with certain PEP medications. Always consult with your prescribing doctor or nurse about any other medications you are currently taking or considering.

 

I Have Completed My 28-Day Course of PEP—What’s Next?


Once you've finished your PEP course, schedule a follow-up appointment with your healthcare provider to get tested for HIV. Your doctor will evaluate your risk factors and may recommend starting PrEP (Pre-Exposure Prophylaxis) for ongoing protection. It’s also advisable to get tested again three months after completing PEP to confirm your status.
