PrEP at IRVINS
Version 1.0 | Last Updated: May 24, 2025

What is PrEP?
PrEP (Pre-Exposure Prophylaxis) is a scientifically proven medical intervention that provides strong protection against HIV. The Centers for Disease Control and Prevention (CDC) in the United States reports that PrEP can be up to 90% effective in preventing HIV infection when taken consistently every day. However, inconsistent use significantly reduces its effectiveness.
PrEP must be taken under the supervision of a doctor experienced in sexual health and antiretroviral (ARV) therapy.
What’s the difference between PrEP and PEP?
PEP: Post-Exposure Prophylaxis — taken after potential exposure to HIV.
PrEP: Pre-Exposure Prophylaxis — taken before potential exposure to HIV.
PrEP stands for Pre-Exposure Prophylaxis which should be taken before getting exposed to HIV infection risks. On the other hand, PEP stands for Post-Exposure Prophylaxis which should be taken after getting exposed to HIV infection risks.
Do I need PrEP?
PrEP is suitable for individuals who frequently engage in risky sexual behavior and/or injecting practices. PrEP is considered eligible for an HIV negative person who:
Have an HIV positive sexual/injecting partner who has not been treated with ARV or has been treated but the viral load is still detected.
Have multiple sexual/injecting partners.
Inconsistently wearing condom while having sex.
Work as a sex worker.
Have risky injecting practice (sharing needles).
Got infected with Sexual Transmitted Infection(s) in the last 3 months.
Lives in an HIV endemic or epidemic area.
PrEP works similarly to daily contraceptive pills: contraceptives prevent pregnancy, while PrEP prevents HIV. For individuals with high-risk sexual behavior but very infrequent sexual activity (e.g., once a year), an “on-demand” dosing option may be considered. For more information, consult directly with an Angsamerah doctor.
Is PrEP safe?
Every medicine has potential side effects. Few people complained of nauseous after taking PrEP. However, no serious or life-threatening side effects have been reported when PrEP is taken correctly.
Can I stop using condoms if I’m taking PrEP regularly?
Not recommended. PrEP does not protect against other sexually transmitted infections such as syphilis, chlamydia, or gonorrhea. Using condoms together with PrEP offers the best protection.
Do I need follow-up appointments after starting PrEP?
Yes. People on PrEP should get a regular check-up every 3 months to check about drug effects, STIs screening, kidney function and many more.
