October 10 is National PrEP Day, a day devoted to talking about one of the most effective HIV-prevention tools we have. PrEP can reduce the chance of acquiring HIV through sex by about 99% when used as prescribed. Yet more than a decade after PrEP became available in the United States, some people still treat taking it as something that requires an explanation.

It does not.

Taking medication to prevent HIV should be viewed exactly as what it is: a person making a deliberate decision about their health. It tells you nothing definitive about how many people they sleep with, their sexual orientation, whether they use condoms, whether they are monogamous, or whether they have HIV.

What it does tell you is that they have chosen HIV prevention.

So, What Exactly Is PrEP?

PrEP stands for pre-exposure prophylaxis. Strip away the medical terminology and the concept is simple: it is medication taken by someone who does not have HIV to greatly reduce the chance of acquiring HIV if exposure occurs.

Think prevention rather than treatment. PrEP is taken before a potential exposure. PEP, or post-exposure prophylaxis, is different; PEP is an emergency medication regimen started after a possible HIV exposure and must be started within 72 hours. (HIV.gov)

PrEP is no longer limited to one daily pill. Current options in the United States include daily oral medications and longer-acting injections. One injectable option is given every two months, and another can be given twice a year. Which option makes sense depends on the individual, their health history, their preferences, access, and discussion with a healthcare provider. (HIV.gov)

What Does PrEP Actually Do?

PrEP makes it much harder for HIV to establish an infection in the body if someone is exposed to the virus.

When used as prescribed, PrEP reduces the chance of acquiring HIV through sex by about 99%. Oral PrEP has been shown to reduce HIV risk from injection drug use by at least 74% when taken as prescribed. Those are extraordinary prevention numbers. (CDC)

PrEP does not require someone to predict every future sexual encounter. It gives people another layer of protection they control themselves. That matters in relationships where partners have different HIV statuses, in dating, during periods when someone has multiple partners, when condom use is inconsistent, or whenever someone simply wants greater control over HIV prevention.

That last reason deserves more respect than it sometimes receives: someone may take PrEP simply because they want to.

They do not owe anyone a more dramatic explanation.

What PrEP Does Not Do

PrEP prevents HIV. It does not prevent every sexually transmitted infection, and it does not prevent pregnancy. Condoms remain useful for reducing the chance of several other STIs and pregnancy. (hiv.gov)

PrEP does not mean a person has HIV. In fact, PrEP is intended for people who do not have HIV, and HIV testing is part of starting and continuing PrEP.

It does not prove someone is having condomless sex. It does not prove someone has multiple partners. It does not prove infidelity. It does not identify someone as gay, bisexual, straight, transgender, promiscuous, sexually reckless, or anything else people decide to project onto a prescription bottle.

And that brings us to the part that medicine cannot fix by itself.

The Stigma Attached to PrEP Is Absurd

There is something deeply backwards about criticizing people for taking steps to prevent HIV.

Research has repeatedly documented PrEP stigma. People taking or considering PrEP have reported fears that others will assume they are promiscuous, HIV-positive, sexually irresponsible, or gay simply from knowing they use the medication. Studies have found that those stereotypes can discourage people from discussing PrEP, starting it, staying on it, or even asking a healthcare provider about it. (PubMed Central (PMC))

Pause on how irrational that is.

For decades, public-health campaigns urged people to protect themselves from HIV. Science developed an extraordinarily effective prevention medication. Then some corners of society decided people using that prevention deserved to be shamed for protecting themselves.

You cannot demand personal responsibility and then ridicule people when they practice it.

Some of this stigma comes from the same old moral policing that has haunted HIV from the beginning. HIV became entangled with judgments about gay men, sex workers, people who use drugs, sexuality, race, gender, poverty, and supposedly “acceptable” sexual behavior. PrEP sometimes inherits those prejudices.

That stigma has real consequences. A 2025 systematic review identified HIV-related stigma as a barrier to PrEP uptake and adherence, reinforcing what earlier studies had already documented. Shame is not an abstract social problem when it discourages people from using an effective HIV-prevention tool. (PubMed Central (PMC))

PrEP Is Not a “Gay Drug”

Gay and bisexual men have played an enormous role in HIV prevention advocacy, and PrEP has been particularly significant within those communities. That history should be recognized rather than erased.

PrEP is still not exclusively for gay men.

Women can use PrEP. Straight men can use PrEP. Bisexual people can use PrEP. Transgender people can use PrEP. People with partners living with HIV can use PrEP. People who inject drugs may benefit from PrEP. People trying to conceive with a partner living with HIV may discuss PrEP with their healthcare provider.

HIV does not check sexual orientation before transmission. HIV prevention should not be trapped inside sexual-orientation stereotypes either.

Taking PrEP Is Responsible Sexual Health

Sexual health has an odd double standard. We praise people for getting vaccines, checking their blood pressure, getting cancer screenings, wearing sunscreen, using birth control, exercising, or taking medication to reduce another preventable health risk. Introduce sex into the discussion, however, and prevention suddenly becomes evidence for somebody else’s moral judgment.

That needs to end.

Someone taking PrEP is making a prevention decision based on their own life. Their reasons belong to them. They should be able to discuss PrEP openly with partners and healthcare providers without having to defend their character.

We should be making HIV prevention easier to discuss, easier to obtain, and less embarrassing to ask about.

National PrEP Day gives us a reason to do exactly that.

PrEP FAQ

Does taking PrEP mean someone has HIV?

No. PrEP is HIV-prevention medication for people who do not have HIV. HIV testing is performed before PrEP is started and continues at regular intervals during PrEP care.

How effective is PrEP?

When taken as prescribed, PrEP reduces the chance of acquiring HIV through sex by about 99%. Oral PrEP reduces the chance associated with injection drug use by at least 74%, according to current CDC guidance. (CDC)

Is PrEP just a daily pill?

No. Daily pills remain available, but injectable forms are available too. Current U.S. options include an injection given every two months and another long-acting option given twice yearly. (HIV.gov)

Is PrEP only for gay and bisexual men?

No. HIV prevention is not restricted by sexual orientation or gender. Adults and adolescents without HIV may be candidates for PrEP based on their circumstances and preferences.

Can women take PrEP?

Yes. PrEP options are available for women, though some medications have different indications depending on how HIV exposure could occur. A healthcare provider can help select an appropriate option.

Do you still need condoms if you take PrEP?

PrEP protects against HIV, but it does not protect against every other STI or pregnancy. Condoms can provide protection that PrEP does not provide, so the two prevention methods serve different purposes. (CDC)

Can someone take PrEP if their partner has HIV?

Yes. PrEP can be considered by an HIV-negative person with a partner living with HIV.

There is another major piece of HIV science here: a person living with HIV who takes treatment and maintains an undetectable viral load does not sexually transmit HIV. That principle is known as U=U: Undetectable = Untransmittable. Some partners may still choose PrEP for personal reassurance, autonomy, or circumstances outside that relationship. (HIV.gov)

What is the difference between PrEP and PEP?

PrEP is prevention taken before potential HIV exposure. PEP is emergency prevention taken after a possible exposure and must be started within 72 hours, with earlier treatment preferred. (HIV.gov)

Does PrEP have side effects?

Some people experience effects such as nausea, headache, stomach discomfort, diarrhea, or fatigue, and these often improve over time. Different PrEP medications have different health considerations, which is one reason follow-up care and appropriate testing are part of PrEP use. (HIV.gov)

Does PrEP start protecting someone immediately?

Do not assume full protection begins with the first dose. How long it takes to reach protective medication levels depends on the PrEP method and the type of potential exposure, so a prescriber should explain when protection can be expected.

Do I have to consider myself “high risk” to ask about PrEP?

No. Current federal guidance states that people may choose PrEP even when they do not fit the traditional lists of behaviors associated with increased HIV exposure. Wanting another HIV-prevention option is itself a legitimate reason to start the conversation. (HIV.gov)

Is PrEP expensive?

Most insurance plans and state Medicaid programs cover some form of PrEP. Federal guidance states that most private health plans covered by Affordable Care Act prevention requirements provide PrEP medication and associated services without out-of-pocket costs, though coverage details and medication options can differ. Assistance programs and community health centers may provide other routes to care for people without adequate coverage. (CDC)

Where can someone get PrEP?

A primary-care provider can prescribe PrEP; an HIV specialist is not required. Sexual-health clinics, community health centers, HIV organizations, telehealth services, and some pharmacists can provide PrEP services depending on location and state law. (HIV.gov)

Prevention Without Apology

National PrEP Day began in 2025 and is observed on October 10. This year, members of Congress introduced a bipartisan House resolution supporting the designation of October 10, 2026, as National PrEP Day and recognizing the role of PrEP in HIV prevention. (GovInfo)

The medication matters. Access matters. Education matters.

So does ending the shame surrounding it.

If someone tells you they take PrEP, you do not know their sexual history. You do not know how many partners they have. You do not know whether they use condoms. You do not know whether their partner lives with HIV.

You know one thing:

They decided HIV prevention mattered.

That should never be something we teach people to hide.
