PrEP & PEP: HIV Prevention You Should Know About

What is PrEP?

PrEP (Pre-Exposure Prophylaxis) is a medication taken to prevent HIV infection before exposure. PrEP consists of two antiretroviral drugs combined in one pill, which work to inhibit the multiplication of the HIV virus if it enters the body, preventing it from establishing itself and spreading.


Who should use PrEP?

PrEP is suitable for individuals who are HIV-negative but are at high risk of contracting the infection in the future, such as:
* Individuals who have sex with an HIV-positive partner with a detectable viral load.
* Men who have sex with men (MSM).
* Individuals who frequently have unprotected sex.
* Individuals who inject drugs and share needles.
* Individuals with a history of frequent sexually transmitted infections (STIs).


How to use PrEP:

There are two main ways to use PrEP:
* Daily PrEP: Taking one pill once a day continuously. This is suitable for individuals with ongoing risk.
* On-Demand PrEP (or 2-1-1): Taking the medication specifically before and after sexual activity. This is suitable for individuals who know when they will be at risk or who are not frequently at risk.

Effectiveness of PrEP:

When used correctly and consistently, PrEP can reduce the risk of HIV infection from sexual activity by over 99% and from sharing needles by over 74%.

What is PEP?

PEP (Post-Exposure Prophylaxis) is a medication taken to prevent HIV infection after exposure. PEP is an antiretroviral medication that must be started as soon as possible, especially within 72 hours of exposure, to prevent HIV from establishing itself in the body.

Who should use PEP?

PEP is suitable for individuals who have recently been exposed to a risk of HIV infection, such as:
* Unprotected sexual activity with someone who may have HIV.
* Condom breakage or slippage during sex.
* Sharing needles.
* Healthcare workers or individuals who have been exposed to blood or bodily fluids from an HIV-positive individual.

How to use PEP:

PEP is taken in pill form once or twice per day (depending on the specific medication) for a duration of 28 days (4 weeks). Starting the medication as soon as possible is crucial, and it must be taken for the full course to ensure maximum effectiveness.

Effectiveness of PEP:

If started within 72 hours of exposure and taken to completion, PEP can reduce the risk of HIV infection by up to 80%.

 * Consult a Doctor: Both PrEP and PEP are medications that require a doctor's consultation before use to assess suitability, conduct HIV testing, and monitor progress.

  • Does Not Prevent Other STIs: PrEP and PEP only prevent HIV. They do not prevent other sexually transmitted infections (STIs) such as syphilis, gonorrhea, or herpes. Therefore, using condoms remains crucial.

    * Condom Use: Consistent and correct condom use is the most effective way to prevent both HIV and other sexually transmitted infections.

    PrEP and PEP are powerful tools in helping to end the HIV epidemic. If you believe you may be at risk or have recently been exposed, do not hesitate to consult a doctor or healthcare professional for appropriate information and care.
