If you think you may have been exposed to HIV, the clock starts ticking immediately.

The one question that matters most is:

“How quickly should I take PEP?”

The short answer is: as soon as possible; every hour counts.

In this article, we’ll explain the best timing for starting PEP, why delays reduce its effectiveness, and what you should do right now if you think you’ve been exposed.

What is PEP?

PEP (Post-Exposure Prophylaxis) is a course of HIV medicines that helps prevent infection after a possible exposure.

Who needs it?

Anyone exposed through unprotected sex, shared needles, blood contact, or sexual assault.

How long to take it?

28 days, without missing doses.

Why timing matters?

PEP only works if started before HIV establishes itself in your body.

When Should You Start PEP?

• Best time to start: Within 2 hours of exposure.
• Maximum window: Within 72 hours (3 days).
• After 72 hours: PEP is no longer effective and is not recommended.

The earlier you start, the higher your chances of preventing HIV.

Think of it like this: HIV moves fast; your protection must move faster.

What Happens If You Delay PEP?

• First 24 hours: Highest chance of success.
• 24–48 hours: Still effective, but less than in the first day.
• 48–72 hours: Can still help, but risk is higher.
• After 72 hours: PEP cannot prevent HIV.

This is why doctors and pharmacists always advise: don’t wait for test results, don’t wait for confirmation, just start PEP.

Why Acting Fast Matters in Nigeria

In Nigeria, many people delay PEP because they:

• Wait to confirm the other person’s HIV status.
• Feel ashamed to seek help.
• Don’t know where to get the medication quickly.

Unfortunately, delays reduce effectiveness. The safest approach is to start PEP immediately and then decide with your healthcare provider whether to continue once more information is available.

Where to Get PEP Fast in Nigeria

You can access PEP through:

• Hospitals and government clinics, some provide it free or subsidized.
• Licensed pharmacies, often faster access without long queues.
• Online platforms like Zivoko, discreet, fast, and reliable delivery anywhere in Nigeria.

Quick Steps If You Think You’ve Been Exposed to HIV

1. Act immediately: don’t wait to “see what happens.”
2. Find PEP within 72 hours; earlier is always better.
3. Get a baseline HIV test; before or soon after starting.
4. Complete the full 28 days; don’t stop halfway.
5. Follow up with HIV tests at 6 weeks, 3 months, and 6 months.

Final Word

The answer to “How quickly should you take PEP?” is simple: immediately.
