PEP: a recent exposure requires urgent assessment

After a possible HIV exposure, seek medical assessment promptly. Do not wait for symptoms or a messaging reply: go to an emergency department if timely assessment is unavailable.

A clinician determines whether post-exposure prophylaxis is indicated, and which tests and follow-up are needed. An initial negative test does not rule out recent infection.

PrEP: individual prevention assessment

The consultation reviews HIV acquisition risk, medical history and required tests to determine whether pre-exposure prophylaxis is appropriate.

HIV, including recent infection, must be excluded before starting. Prescribing and follow-up are individualized. PrEP does not prevent other sexually transmitted infections or replace urgent assessment after an exposure.

Confidential care and follow-up

We can review when the exposure occurred, medications used and previous tests. Bring available results, but do not delay urgent assessment while gathering documents. Follow-up testing and continued prevention are discussed during the visit.

When urgent care is needed

If you have difficulty breathing, confusion, fainting or rapid deterioration, go to an emergency department. WhatsApp and the booking page do not provide emergency monitoring.
