PEP in Kathmandu

  • Time-critical — within ~72 hours of exposure; earlier is better; say it is urgent when you contact.
  • Assessment first — whether PEP is actually indicated is decided at assessment, not assumed.
  • 28-day course — completed fully; stopping early loses protection.
  • Follow-up testing — HIV testing at right intervals after course confirms outcome.

What PEP Is — and Why It Is Urgent

HIV post-exposure prophylaxis is a 28-day course of antiretroviral medication started after a high-risk exposure to prevent HIV from establishing infection. It is one of few genuinely time-critical interventions in sexual health: it must begin within ~72 hours of exposure — earlier better — and its effectiveness falls sharply after that window.

PEP is not a routine precaution — it is indicated for specific higher-risk situations: condomless anal or vaginal sex with a partner known or likely to be HIV-positive, shared injection equipment, or significant occupational exposure. It is not indicated for every exposure — low-risk contact does not warrant a month of antiretrovirals — and part of urgent assessment is deciding honestly whether it is actually needed.

If your exposure was within roughly 72 hours and may be high-risk, treat this as urgent — attend promptly rather than waiting for a routine appointment. Every hour within window matters.

When PEP Is Indicated

The clearest indications: condomless anal or vaginal sex with a partner known to be HIV-positive (or with a high chance of being positive — for example, a partner from a higher-prevalence situation whose status is unknown), particularly receptive anal sex which carries highest per-act risk; sharing needles or injection equipment; and significant occupational exposure like a needlestick with a source patient known or suspected positive.

PEP is generally not indicated for lower-risk contact — oral sex alone, protected sex with an intact condom, or contact where source is confirmed to be on suppressive ART (undetectable = effectively no transmission, U=U). The assessment weighs specific act, timing, and source situation honestly — recommending PEP where it is genuinely indicated, and saying so honestly where it is not.

Clearly Indicated

Condomless sex with known/likely-positive partner; shared needles; significant occupational exposure.

Highest-Risk Acts

Receptive anal sex carries highest per-act transmission risk.

Generally Not Indicated

Oral-only, intact condom, or a source confirmed undetectable (U=U).

Weighed Honestly

The act, timing and source assessed — not reflexively prescribed.

The Urgent Assessment

The assessment is fast because it has to be — questions are focused: what happened, when, nature of act, what is known about source, and whether any baseline issues need checking before starting. Baseline HIV testing, renal function and relevant history are taken; decision to start is made within same visit where possible.

For high-risk exposures with source available, source testing can clarify whether PEP is needed at all — a source with a confirmed undetectable viral load changes calculus entirely. Where source cannot be tested, assessment relies on act and context.

Focused & Fast

The assessment is designed for speed — window does not wait.

Baseline Testing

HIV baseline plus relevant checks before starting.

Source Testing Where Possible

A source test can clarify whether PEP is needed at all.

Same-Visit Decision

The start/no-start decision is made at assessment where possible.

The 28-Day Course

PEP is a 28-day course — typically a once-daily combination — taken completely. Stopping early loses protection; course must be finished. Side-effects are usually manageable (nausea and fatigue are commonest early effects) and are addressed rather than endured.

During and after course, follow-up matters: adherence support if any doses are missed, interim symptom review, and scheduled HIV testing that confirms outcome. The exposure is also right moment to discuss ongoing prevention — whether PrEP (pre-exposure prophylaxis) is indicated going forward, and other infections exposure may have carried.

28 Days Complete

The full course is required — stopping early loses protection.

Manageable Side-Effects

Nausea and fatigue are commonest early — addressed, not endured.

Follow-Up Testing

Scheduled HIV testing at right intervals confirms outcome.

Prevention Discussion

PrEP and broader screening — right moment to plan forward.

PEP, PrEP & Ongoing Prevention

PEP is reactive — after an exposure that has happened. For people with ongoing risk, PrEP (pre-exposure prophylaxis) is proactive equivalent — daily or event-based medication that prevents HIV before exposure. The PEP consultation is often right time to discuss whether ongoing PrEP is better long-term answer than repeated PEP courses.

The same visit is right moment for broader screening — a high-risk exposure can carry chlamydia, gonorrhea, syphilis and hepatitis B alongside HIV — and for vaccination where indicated (hepatitis B vaccination is ~95% protective for unvaccinated).

PEP = Reactive

After a specific exposure — a one-time course.

PrEP = Proactive

For ongoing risk — daily or event-based prevention.

Broader Screening

The same exposure may carry other STIs — screen for all of them.

Hepatitis B Vaccine

~95% protective — offered where not yet immune.

Frequently Asked Questions

How long do I have to get PEP?

Within ~72 hours of exposure — earlier is better; after that window effectiveness falls sharply.

Does every exposure need PEP?

No — it is for high-risk exposures; oral-only, intact-condom, or undetectable-source exposures are assessed honestly.

What if my partner is on HIV treatment?

A sustained undetectable viral load means effectively no transmission (U=U) — PEP may not be indicated; source testing helps.

What does course involve?

28 days of medication, typically once daily — completed fully; side-effects managed, not endured.

Do I need testing after PEP?

Yes — scheduled HIV testing after course confirms outcome.

Should I be on PrEP instead?

If you have ongoing risk, PrEP is often better long-term answer — we discuss it at same visit.
