HIV Prevention • Exposure Assessment

My condom broke during sex.
Do I need PEP?

Not every condom failure puts you at meaningful HIV risk. But some situations genuinely do. This guide helps you work out where you stand so you can act without panic and without wasting time you do not have.


⏳  If you are within 72 hours of a condom failure and your partner’s status is unknown, do not wait.  Assess Your Risk Now →

Let’s be honest about what just happened. A condom broke, slipped, or was used incorrectly. There was unprotected contact. And now you’re searching the internet trying to figure out whether you need to worry.

Here’s what matters: the answer depends on your specific situation, not a one-size-fits-all rule. Some condom failures carry very little HIV risk. Others warrant immediate action. This article walks you through the key factors so you can make a clear-headed decision.

According to the Centers for Disease Control and Prevention (CDC), PEP must be started within 72 hours of a possible HIV exposure to be effective. So whatever you decide, make that decision quickly.


The Three Key Questions

What actually determines your risk level.

When a healthcare provider assesses whether you need PEP after a condom failure, three things matter most. Think through each of these honestly.

Higher concern
Your partner’s HIV status
If your partner is HIV-positive and not on treatment (or on treatment but not virally suppressed), the risk from unprotected contact is real. If their status is unknown, that uncertainty itself is a reason to consider PEP.
Lower concern
Partner is HIV-negative or undetectable
If your partner has tested HIV-negative recently, or is HIV-positive but on treatment with a confirmed undetectable viral load, the risk from this exposure is very low. The U=U principle means an undetectable person cannot sexually transmit HIV.
Higher concern
Type of sexual contact
Receptive anal sex carries the highest per-act HIV transmission risk. Receptive vaginal sex carries moderate risk. Insertive sex carries lower but still meaningful risk. The nature of the contact matters for assessing how much the condom failure elevated your exposure.
Important factor
Whether ejaculation occurred
Ejaculation inside the body increases exposure to a larger volume of potentially infectious fluid. However, pre-ejaculatory fluid (pre-cum) can also contain HIV, so ejaculation is not the only risk factor. A condom that broke before ejaculation still represents an exposure worth taking seriously.

Other factors that can increase your personal risk include existing genital sores or ulcers, active sexually transmitted infections, and bleeding that occurred during sex. All of these make it easier for HIV to enter the bloodstream.


Should I Start PEP?

How to make the call.

Here is the honest principle: if there is any reasonable possibility your partner could be HIV-positive, and the contact involved carries meaningful transmission risk, you should start PEP within 72 hours.

You do not need certainty. PEP exists precisely for situations of uncertainty. If you take PEP and it turns out you didn’t strictly need it, you’ll have spent 28 days on medication with manageable side effects. If you don’t take it when you needed it, the consequences are permanent. Most clinical guidelines, including those from the World Health Organization, recommend erring toward treatment when the exposure was significant and the source’s status is unknown.

If you are genuinely unsure, contact a doctor or clinical team who can review your specific situation. At Zivoko, you can message our team on WhatsApp to talk through your exposure before ordering. We will tell you honestly whether we think PEP is warranted.

Earlier is better. PEP started within 2 hours of an exposure is significantly more effective than PEP started at 60 or 70 hours. Do not spend half a day researching and second-guessing. If you think you might need PEP, reach out now. You can always confirm eligibility with a clinical team first.

If You Decide Not to Take PEP

What to do even if PEP is not needed for this exposure.

Even in lower-risk situations, a condom failure is worth following up on. You should still:

  • Get an HIV test at the appropriate time. A 4th generation test at 45 days from the exposure gives you a reliable negative result. A 3rd generation test needs 90 days. Read our guide on the HIV window period so you know when your test result can actually be trusted.
  • Test for other STIs. Condom failure also creates exposure to gonorrhoea, chlamydia, syphilis, and other infections that PEP does not cover. A full sexual health screen at a laboratory two weeks after the exposure is sensible regardless of whether you take PEP.
  • Consider starting PrEP. If this situation has made you realise that your level of ongoing HIV risk is real, PrEP is the daily prevention option that protects you continuously before any future exposure. You would never need to have this conversation with yourself again.

Frequently Asked Questions

Other questions you might have right now.

QI am on PrEP. Do I still need PEP after a condom failure?

If you have been taking PrEP consistently every day, a condom failure does not require PEP. PrEP provides continuous HIV protection when taken correctly and on schedule.

If you have been missing doses, or if you started PrEP less than seven days ago, speak with a doctor or pharmacist to assess whether additional protection is needed for this specific exposure.

QMore than 72 hours have passed. Is there anything I can do?

Unfortunately no. PEP is not effective or recommended after the 72-hour window has closed. It works by preventing HIV from replicating in the days immediately following an exposure. Beyond that window, the window of opportunity for that mechanism has passed.

What you can do is focus on HIV testing at the right time, get a full STI screen, and talk to a doctor about starting PrEP if you have ongoing HIV risk. PrEP means you are protected continuously, so you won’t find yourself in this position again.

QDoes PEP cover other infections too, or just HIV?

PEP only prevents HIV. A condom failure also puts you at potential risk for gonorrhoea, chlamydia, syphilis, hepatitis B, and herpes. None of these are covered by PEP.

A full sexual health screen at a laboratory is recommended within two weeks of any significant exposure. Many people time this to coincide with their first post-PEP HIV follow-up test, which makes practical sense.

QWhat do I need to share when contacting Zivoko about PEP?

You only need to share what is clinically relevant. That typically means: the date and approximate time of the exposure, the type of contact involved, whether ejaculation occurred, and what you know about your partner’s HIV status (or that it is unknown).

You don’t need to share names or any identifying details about yourself or your partner. The process is discreet, professional, and completely non-judgmental.
