PEP is unlikely to work if it’s started after 3 days (72 hours) and it won’t usually be prescribed after this time. It is best to start taking PEP within 1 day (24 hours) of being exposed to HIV. PEP makes infection with HIV less likely. However, it’s not a cure for HIV and it doesn’t work in all cases.

What is the success rate of pep?

Adherence to a full 28-day course of ARVs is critical to the effectiveness of the intervention. Recent evidence shows PEP uptake has been insufficient: only 57% of the people who initiated PEP have completed the full course and rates were even lower at 40% for victims of sexual assault.

What does PEP do to the body?

PEP involves a 4-week course of HIV treatment that helps prevent someone from HIV infection. PEP works by stopping the virus from replicating after recent exposure. The cells originally infected with HIV die naturally within a short period of time, reducing the likelihood for HIV to establish itself in the body.

Is Pep effective after 5 days?

Give yourself the best chance of it working. To be most effective, PEP should be started within a few hours of exposure to HIV. If it is not started within 72 hours (3 days) it is not likely to work. So the sooner it’s started after exposure, the greater the chance of working.

After a course of PEP you need to wait 28 days before testing for HIV. This is because PEP can delay infection.

What causes pep failure?

The use of postexposure prophylaxis (PEP) after occupational HIV exposure reduces the risk for HIV acquisition by >80%. PEP failure, when it occurs, is usually attributed to delayed initiation, transmitted drug resistance, or suboptimal medication adherence.

Can Pep cause liver damage?

In addition, three patients reported rash a median of ten days after the initiation of PEP, leading one patient to discontinue therapy. Two patients developed mild liver toxicities (grade 1 and grade 2) 14 and 28 days after starting PEP, and there were two instances of severe liver toxicity.

Can I take PEP for 30 days?

Cases had significantly lower odds of having taken zidovudine after exposure compared to controls (OR 0.19, 95% CI 0.06 – 0.52). Another study suggested PEP was approximately 65% efficacious in preventing transmission to infants born to untreated HIV infected women when initiated within 48 hours of peripartum exposure.

Why does PEP have to be taken for 28 days?

Post-exposure prophylaxis (PEP) is the use of short-term antiretroviral therapy (ART) to reduce the risk of acquisition of HIV infection following exposure. Current guidelines recommend a 28-day course of ART within 36–72 hours of exposure to HIV.

Can Pep cause flu like symptoms?

Contact your doctor immediately if you experience any flu-like symptoms, skin rash, fever, swollen glands, or severe fatigue 2-14 weeks after exposure. What happens next?
