Prophylaxis or PrEP is an HIV prevention strategy where an HIV negative person
takes a daily pill to reduce their risk of contracting HIV. It’s important to
note that PrEP is not the same as PEP or Post-Exposure Prophylaxis, which HIV
treatment given to individuals within 72 hours after exposure to HIV to prevent
infection from taking hold.
approved PrEP regimen is Truvada, a two drug combo, which blocks an enzyme
called HIV reverse transcriptase. HIV relies on this enzyme to make new copies
of itself. So Truvada prevents the HIV virus from multiplying and establishing
infection in the body.
HIV enzyme, it protects against HIV infection, but it does not prevent against
pregnancy or other sexually transmitted infections or STI’s. Therefore, people
taking PrEP should also get regular HIV testing, to make sure they haven’t been
recently infected. As well as STI testing and treatment if necessary.
to reduce the risk of HIV infection in gay and bisexual men, transgender women
and heterosexual men and women, as well as people who inject drugs. PrEP does
not treat HIV. It’s meant to prevent HIV from establishing infection so it
should not be taken by someone who already has HIV. People who want to start PrEP
must first be tested for HIV infection.
headlines over the last two years, and the messages haven’t always been clear.
Let’s look at three myths about PrEP, and see what the facts really are.
of PrEP in gay and bisexual men and transgender women, researchers found an
overall 42% reduction in HIV transmission. However, when the researchers looked
at levels of Truvada in the blood samples, they found that
for people who took four PrEP pills per week, protection was approximately 96%.
For people who took PrEP daily as recommended, protection was estimated at more
than 99%. So the take home message – PrEP works if you take it as prescribed,
PrEP studies have reported side effects such as nausea, headaches, or weight
loss in the first few weeks of taking PrEP. Most of these side effects went
away on their own or when PrEP was stopped. And the majority of people didn’t
have them at all. For example, one clinical trial reported moderate nausea only
22 times among the 1251 people that started to take PrEP over a study period of
more than two years. A recent analysis showed that some people taking PrEP can
have a slight increase in serum creatinine, an indicator of reduced kidney
function. But, these levels returned to normal after PrEP was stopped. Just to
be safe, people who take PrEP should have regular monitoring for kidney health.
Another analysis found a slight loss in bone and mineral density in study
participants taking PrEP. Although this bone loss did not worsen with long term
use. Truvada was chosen for use as PrEP, in part because it is safe and
well tolerated. Like most drugs, some mild side effects are possible. But
again, side effects reported with PrEP went away over time or when PrEP was
stopped. Also, there are other drugs currently in clinical trials that may have
fewer side effects.
available by prescription from doctors, nurse practitioners,
and physicians assistants, and most health care plans cover PREP. Without
insurance, Truvada PrEP can cost upwards of $1800 per month. But few people
actually pay this full stickered price. There are medication assistance
programs through Gilead Sciences that may be able to cover some or all of the
cost of PrEP, whether or not you have insurance. Keep in mind that depending on
how you are accessing PrEP, it may take several weeks to get your prescription
filled the first time.
way to prevent HIV infection. When used correctly and consistently, condoms are
an important tool for reducing HIV risk, as well as preventing against other
STI’s and pregnancy. For people who do not use condoms every time they have
sex, PrEP provides effective protection against HIV. The choice to use PrEP,
like the choice to use condoms is personal. The important thing is to find an
HIV prevention strategy that works for you.

More Breaking from U.S. Conference on AIDS: Gilead is raising income levels for their Assistance Program to 500% of FPL (or approx $58,350). So you may be able to get PrEP paid for if you are making below that amount and can’t afford the drug. Also being told that the Co-Pay Assistance program is expanding from $200 to $300 per month. This is an important breakthrough, for #PrEP consumers!
