Prevent HIV by taking ONE pill every day
A pill a day can take HIV risk away!
Learn how PrEP can help prevent HIV infection for men who have sex with men, people who share needles to inject drugs, and sexual partners of individuals living with HIV.
Every year, approximately 70% of new HIV infections in Contra Costa County are among men who have sex with men. Studies have shown that PrEP reduces the risk of getting HIV from sex by about 99% when taken daily.
PrEP, a once-a-day pill, has been proven to lower the risk of getting HIV among people who share needles to inject drugs by more than 74%.
What is Pre-Exposure Prophylaxis (PrEP)?
PrEP stands for pre-exposure prophylaxis.
Pre = Before
Exposure = Coming into contact with HIV
Prophylaxis = Treatment to prevent an infection from happening
PrEP is a once daily pill (prescription only) taken by an HIV negative individual that reduces their risk of HIV infection, it is not a cure for HIV. PrEP can stop HIV from taking hold and spreading throughout your body.
PrEP is highly effective for preventing HIV. When taken daily, PrEP has been shown to reduce the risk of HIV infection through sex by about 99% and by at least 74% among people who share needles. PrEP does not protect against other sexually transmitted diseases (STDs) or pregnancy, so using effective birth control methods and condoms are still important for the sexual health of individuals taking PrEP.
There are currently two approved medications available for daily PrEP—Truvada® and Descovy®. Truvada® for PrEP is recommended to prevent HIV for all people at risk through sex or injection drug use. Descovy® for PrEP is recommended to prevent HIV for people at risk through sex only, excluding people at risk through receptive vaginal sex. Descovy® has not yet been studied for HIV prevention for receptive vaginal sex, so it may not be appropriate for some people. Please click here for a side by side comparison of Truvada® and Descovy®.
PrEP is different from Post-Exposure Prophylaxis (PEP). PEP is a month-long course of medications that an HIV negative individual takes after they may have come into contact with HIV to reduce their risk of becoming infected. The Contra Costa County Public Health Department recommends starting PEP within 36 hours after a possible exposure to HIV. Exposures beyond 36 hours may warrant PEP on a case-by-case basis. If you may have been exposed to HIV and would like more information on PEP, please contact your primary care provider, your closest Planned Parenthood, or ask about PEP at your local emergency room. If you are refused PEP at any Emergency Department or medical clinic, please contact the Contra Costa Public Health Department, HIV/AIDS and STD Program at firstname.lastname@example.org or 925-412-5431 (Monday through Friday 8:30 am to 5:00 pm).
What is Post-Exposure Prophylaxis (PEP)?
PEP stands for post-exposure prophylaxis. This means taking antiretroviral medicine (ART) to prevent HIV after a possible exposure.
PEP must be started within 72 hours after a recent possible exposure to HIV, but the sooner you start PEP, the better. The Contra Costa County Public Health Department recommends that individuals start PEP within 36 hours after possible exposure to HIV. If you're prescribed PEP, you'll need to take it once or twice daily for 28 days. PEP is highly effective in preventing HIV when administered correctly.
If taken within 72 hours after possible exposure, PEP is highly effective in preventing HIV. To be safe, you should take other actions to protect your partners while you are taking PEP. This includes always using condoms with sexual partners and not sharing needles, syringes, or other equipment to inject drugs.
Talk to your health care provider, an emergency room doctor, or an urgent care provider right away (within 72 hours) if you think you've recently been exposed to HIV:
- during sex (for example, if the condom broke)
- through sharing needles, syringes, or other equipment to inject drugs
- if you have been sexually assaulted
PEP is for emergency situations
- PEP is given after a possible exposure to HIV.
- PEP is not a substitute for regular use of other HIV prevention methods, including condoms and PrEP.
- PEP is not the right choice for people who may be exposed to HIV frequently.
Talk to your health care provider about PrEP (pre-exposure prophylaxis) if you are at ongoing risk for HIV.
- PEP is safe but may cause side effects like nausea in some people.
- These side effects can be treated and aren't life-threatening.
Your health care provider or an emergency room doctor can prescribe PEP. Talk to them right away (within 72 hours) if you think you've recently been exposed to HIV.
If you are refused PEP at any Emergency Department or medical clinic, please contact the Contra Costa Public Health Department, HIV/AIDS and STD Program at email@example.com or 925-412-5431 (Monday through Friday 8:30 am to 5:00 pm).
PEP is not the right choice for people who may be frequently exposed to HIV, including people who have sex without a condom with a partner who is HIV-positive or a partner with an unknown HIV status. PEP is given after a potential exposure to HIV, so more drugs and higher doses are needed to block infection than with PrEP (Pre-Exposure Prophylaxis).

Is PrEP right for you?
PrEP is a safe and highly effective HIV prevention tool that can provide an opportunity to improve your sexual health and wellness. PrEP is for people who are HIV-negative and vulnerable to getting HIV from sex or injection drug use. PrEP can be prescribed for gay and bisexual men, for heterosexual men and women, for transgender individuals, and for genderqueer or nonbinary people.
PrEP may be a good choice for you if you test negative for HIV and any of the following apply to you:
You have had anal or vaginal sex in the past 6 months and:
- have a sexual partner with HIV (especially if the partner has an unknown or detectable viral load)
- have not consistently used condoms
- have been diagnosed with an STD in the past 6 months
You inject drugs and:
- have an injection partner with HIV
- share needles, syringes, or other equipment to inject drugs (for example, cookers)
You have been prescribed PEP (post-exposure prophylaxis) and:
- engage in behaviors that may put you at risk
- have used multiple courses of PEP
If you are considering getting pregnant and your partner has HIV, talk to your doctor about PrEP. PrEP may be an option to help protect you and your baby from getting HIV while you try to get pregnant, during pregnancy, and/or while breastfeeding.
Can adolescents take PrEP?
Yes. PrEP is approved for use by adolescents without HIV who weigh at least 77 pounds (35 kg) and who are at risk for getting HIV from sex or injection drug use.
If you identify with any of the above, please talk with your medical provider or the Contra Costa County PrEP Navigator.
Learn more information about PrEP from the Centers for Disease Control and Prevention.
How do I take PrEP?
- Meet with a health care provider to find out if PrEP is right for you.
- Your health care provider will test you for HIV, sexually transmitted diseases (STDs), and will conduct lab work to make sure PrEP is safe for you.
- PrEP is a single pill taken once daily. You can take it with or without food. In order to benefit from this medication, taking it every day at the same time is important
- You will need to return to your health care provider every three months for repeat HIV/STD tests, prescription refills, and follow-up
- Individuals who only have anal sex may choose a non-daily dosing regimen called 2-1-1 in which they take pills before and after sex. This non-daily dosing regimen can only be done with Truvada®. Ask your PrEP provider if 2-1-1 is safe for you.
- If you need help paying for PrEP or finding a health care provider, contact our PrEP Navigator using the online form found here.
Is PrEP safe? What are the side effects?
There are two different medications that have been approved for PrEP: Truvada® and Descovy®. Each medication is proven to be safe and most people on PrEP take it with little or no side effects.
Short Term Side Effects: When starting PrEP with either Truvada® or Descovy®, about 1 in 10 individuals may experience nausea, diarrhea and/or headaches. These symptoms usually go away in a few weeks. Other side effects are rare (see below).
Rare Side Effects:
Truvada® Descovy® Small decrease in kidney function, which will go back to normal if you stop the medication Small increase in LDL cholesterol, often called the "bad" cholesterol Slightly decreased bone density, but no increased risk of fractures Slight increase in body weight
Ask your PrEP provider for more information so you can make the best choice for yourself.
How Do I Pay For PrEP?
Paying for PrEP can be expensive, but we may be able to help! If you need help paying for your PrEP prescription, doctor visits, or labs there are programs that can help lower or eliminate the cost (scroll to the table at the bottom of the page for more information).
Paying For PrEP If You Are Uninsured
The State of California's PrEP Assistance Program (PrEP-AP) may be able to help cover medical costs related to getting on PrEP if you do not have insurance.
What does the PrEP-AP Cover?
- Certain PrEP-related medical services, such as doctor visits and labs
- Medications used to treat sexually transmitted infections (the PrEP medication will be covered for free by the drug manufacturer*)
- If you are a current PrEP-AP client who has stopped PrEP and are worried about a potential exposure to HIV within 72 hours, the PrEP-AP may be able to help pay for nPEP (non-occupational post-exposure prophylaxis), if clinically recommended. Existing PrEP-AP clients will be evaluated by their healthcare provider for PEP
NOTE: Clients are required to see a provider in the PrEP-AP Provider Network. Please click this link to search for a provider.
You May Qualify if you are:
- A California resident, regardless of immigration status
- An adult age 18 or older or minors between the ages of 12 and 17 who weigh at least 77 lbs.
