How does PrEP help prevent HIV?
PrEP (Pre-Exposure Prophylaxis) helps prevent HIV by providing a proactive defense for individuals who are at risk of exposure to the virus. When taken consistently as prescribed, PrEP medications work in the following ways:
Blocking HIV Replication: PrEP medications contain antiretroviral drugs that prevent HIV from replicating in the body. If the virus enters the bloodstream, the drugs stop it from establishing an infection.
Maintaining Drug Levels: By maintaining a consistent level of the medication in the bloodstream, PrEP ensures that the antiretroviral drugs are always present to combat the virus immediately upon exposure.
Preventing Cell Infection: The medications in PrEP interfere with the virus’s ability to bind to and enter human cells, particularly the CD4 cells (T cells), which are critical for the immune response.
Is PrEP effective in preventing HIV?
Pre-Exposure Prophylaxis (PrEP) is highly effective in preventing HIV when taken consistently and correctly. Here are key points about its effectiveness:
High Effectiveness: When taken daily, PrEP has been shown to reduce the risk of HIV infection by up to 99% among individuals who are at high risk of HIV exposure through sexual activity or injection drug use.
Consistent Use: PrEP effectiveness depends on consistent adherence to the prescribed regimen. Skipping doses or irregular use can reduce its protective effect.
- Additional Protection: PrEP does not provide protection against other sexually transmitted infections (STIs) or blood-borne infections. It is essential to continue using condoms and practicing safer sex practices to reduce the risk of STIs.
PrEP is a highly effective prevention tool against HIV when taken consistently and as prescribed. It offers significant protection to individuals at high risk of HIV exposure, contributing to efforts to reduce new HIV infections globally.
PrEP starts to workin?
When taken as prescribed, PrEP reaches its maximum protection against HIV after about 7 days of daily use. This means that for most people, if they start taking PrEP daily, it typically takes about a week for the medication to build up to effective levels in the body.
It is important for individuals considering PrEP to discuss their specific situation with a healthcare provider, who can provide guidance on when and how to start PrEP effectively to maximize its preventive benefits.
Is PrEP for Women?
Yes, Pre-Exposure Prophylaxis (PrEP) is for both men and women who are at risk of HIV infection. While early studies and messaging around PrEP initially focused on men who have sex with men (MSM), PrEP has been proven effective and recommended for use by women as well.
PrEP is an important tool in HIV prevention for women, alongside other prevention strategies. It’s essential for women to have access to accurate information and healthcare support to make informed decisions about their sexual health and HIV prevention options.

Can PrEP be taken with other medication?
Pre-Exposure Prophylaxis (PrEP) can generally be taken with other medications, but it’s important to discuss any medications you are currently taking with your healthcare provider before starting PrEP. This ensures that there are no potential interactions that could affect the effectiveness or safety of either medication.
Before starting PrEP, inform your healthcare provider about all medications you are taking, including prescription medications, over-the-counter drugs, vitamins, and supplements.
While PrEP generally does not interact with most medications, there are some exceptions. For instance, certain antifungal medications, antibiotics, or medications used to treat hepatitis C may interact with PrEP. Your healthcare provider can assess any potential interactions and adjust your treatment plan accordingly.
