Definition and Meaning
PrEP (noun) stands for Pre-Exposure Prophylaxis. It refers to a preventive medical treatment where people who are HIV-negative take medication daily to reduce their risk of contracting HIV (Human Immunodeficiency Virus). When taken consistently, PrEP can lower the risk of sexual transmission of HIV by about 99% and by at least 74% among people who inject drugs.
Pronunciation
/prep/ (same as the word “prep” in “prepare”)
Grammatical Formation
- Noun (uncountable): PrEP
- Often used with verbs like take, use, start, prescribe, be on
- Adjective: PrEP-related (e.g., PrEP-related awareness)
Word Comparisons
- PrEP vs. PEP: PrEP is taken before possible HIV exposure; PEP (Post-Exposure Prophylaxis) is taken after a potential exposure.
- PrEP vs. ART: PrEP is for people without HIV to prevent it; ART (antiretroviral therapy) is for people living with HIV to manage the virus.
- PrEP vs. Condom: Both reduce HIV risk. Condoms also prevent pregnancy and other STIs; PrEP does not.
Prepositional Use and Nuance
- On PrEP: “They’ve been on PrEP for a year now.”
- Take PrEP: “He started taking PrEP after discussing it with his doctor.”
- Access to PrEP: “Community clinics offer easier access to PrEP.”
- Prescribed PrEP: “She was prescribed PrEP due to her partner’s HIV status.”
Real-life Examples
- Many sexually active people at higher risk for HIV—such as gay and bisexual men, sex workers, or people in serodiscordant relationships—take PrEP daily.
- PrEP does not protect against other STIs or pregnancy, so it’s often used alongside condoms.
- Newer forms like long-acting injectable PrEP are becoming more accessible.
Simple Explanation
PrEP is medicine that helps people avoid getting HIV. You take it before sex or contact with HIV. If taken daily, it can almost completely stop the virus from infecting you.

Connection to Sexuality
Absolutely. PrEP is deeply connected to sexual health and sexuality. It is primarily used to reduce the risk of HIV transmission through sex, making it highly relevant for LGBTQ+ communities, sex workers, people with multiple partners, and others seeking control over their sexual health. It reflects the intersection of sexual behavior, public health, consent, and empowerment, promoting safer sex without stigma.
