How does PEP work in 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.

How effective is the PEP treatment?

How well does PEP work? PEP does not prevent 100\% of HIV infections but it is very effective at preventing HIV if used consistently and correctly. Observational research suggests that PEP can reduce the risk of getting HIV by more than 80\%, which means some people in the studies acquired HIV despite taking PEP.

What is the success rate of PEP?

PEP is effective in preventing HIV infection when it’s taken correctly, but it’s not 100\% effective. PEP can lower the risk of getting HIV infection by more than 80\%.

How does a prophylaxis work?

PEP, or post-exposure prophylaxis, is a short course of HIV medicines taken very soon after a possible exposure to HIV to prevent the virus from taking hold in your body. You must start it within 72 hours (3 days) after a possible exposure to HIV, or it won’t work. Every hour counts!

How effective is PEP after 12 hours?

If you believe you have been exposed to HIV, you should seek PEP treatment as quickly as possible. PEP must be taken within 72 hours of exposure or it will have little to no effect in preventing an HIV transmission. In fact, PEP is the most effective when it is taken within 24 hours.

How effective is PEP after 48 hours?

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.

Is taking PEP for 14 days effective?

There have been small animal studies that have suggested 28 days is optimal8 and a case-control study of health care workers14 showed failure of PEP when the 28 days of treatment was not completed. Therefore, current guidelines recommend that 4 weeks of PEP should be used.

How bad are pep side effects?

The most common side-effects of emtricitabine/tenofovir are diarrhoea, being sick (vomiting), feeling sick (nausea), dizziness, headache, rash, feeling weak, pain, stomach pain, difficulty sleeping, abnormal dreams, feeling bloated, flatulence, allergic reactions, such as wheezing, swelling or feeling light-headed.

Is 7 days of PEP enough?

With updated recommendations for: If the full course of PEP medications cannot be provided, then at least a 7-day starter pack should be provided to patients with occupational or non-occupational exposures and to sexual assault patients who are ≥18 years old.

How do you do post exposure prophylaxis?

PEP is a combination of three drugs. You take them once or twice a day for 28 days: For adults, the CDC recommends tenofovir, emtricitabine (these two drugs come in one pill), and a third drug, either raltegravir or dolutegravir.

When should you take PrEP after being exposed?

Ideally PEP should begin within an hour of possible infection and no longer than 72 hours after exposure, whereas PrEP should be taken during (before and after) the time high-risk exposure may take place.

Can I test positive while on PEP?

After a course of PEP you need to wait 28 days before testing for HIV. This is because PEP can delay infection. During the time on PEP, the meds might be keeping your viral load undetectable.

What is the risk of HIV post exposure?

Risk of Transmission. The risk of transmission of HIV after exposure to body fluids from an HIV-infected patient is generally low.Typical exposures result from percutaneous exposure to contaminated sharps such as needles, scalpels, and broken glass.

Can I drink alcohol on post exposure prophylaxis (PEP)?

Post Exposure Prophylaxis (PEP) for HIV Metoclopramide Take 1 tablet, 3 times per day for nausea if needed. • Do not drink alcohol while taking this medication. • Women under the age of 20 should not take this medicine. Storing the medication • Keep these medications out of the sight and reach of children.

Can Pep work after 72 hours?

No guidelines recommend any benefit from taking PEP after longer than 72 hours. If the PEP has worked, or the person was not initially infected, this will show as a negative HIV test at one month and three months after the PEP treatment finishes.

How long is PEP treatment?

PEP is a course of anti-HIV medication. You must start the treatment as soon as possible after you’ve been exposed to HIV, ideally within a few hours. The medicines must be taken every day for 28 days (4 weeks). PEP is unlikely to work if it’s started after 3 days (72 hours) and it won’t usually be prescribed after this time.
