What is PrEP?

PrEP is a pill that pre­vents you from catch­ing HIV. PrEP is both safe to use and effec­tive. This has been sci­en­tif­i­cal­ly proven. PrEP has been avail­able to the pub­lic in the Unit­ed States since 2012, and became avail­able in the Nether­lands in 2016. PrEP is not cov­ered by Dutch health insur­ance, but you can get a month’s worth of PrEP for as lit­tle as 20 euros. PrEP can only be bought if you have a doctor’s pre­scrip­tion. Read our Step-by-step Guide to find out how to get PrEP in the Nether­lands.

What about PrEP and the coronavirus?

There is no evi­dence that PrEP pro­tects you in any way against the coro­n­avirus (COVID-19). A good overview of infor­ma­tion on sex and the coro­n­avirus can be found at Man tot Man.

Con­cern­ing COVID vac­ci­na­tion, no inter­ac­tions are expect­ed with PrEP. The Dutch HIV Asso­ci­a­tion (Hiv Verenig­ing) has com­piled an FAQ cov­er­ing, among oth­er things, the ques­tion of inter­ac­tions between COVID vac­ci­na­tion and HIV med­ica­tion (in Dutch). This infor­ma­tion is rel­e­vant for PrEP users as well as the med­ica­tion used as PrEP is used for treat­ment of HIV as well.

How can I get PrEP as cheap as possible?

GGD STI clin­ics offer PrEP for €7,50 per 30 pills as part of the nation­al PrEP pro­gramme. All asso­ci­at­ed care is free of charge at the GGD. How­ev­er, the nation­al PrEP pro­gramme has a lim­it­ed capac­i­ty. Many GGD clin­ics have wait­ing lists, and it could be that the GGD in your region has run out of spots alto­geth­er. Your local GGD can give you all infor­ma­tion on the pos­si­bilites. If you can’t or don’t want to wait, ask your GP to pre­scribe PrEP. Prices dif­fer between phar­ma­cies (see our price list), start­ing at about €20 a month.

What if I forgot a pill?

When using dai­ly:
Don’t pan­ic! If you use PrEP dai­ly, you can take your pill up to 12 hours after you should have tak­en it. If more than 12 hours have passed, it is bet­ter to skip the pill. Even if you for­get your pill once or twice a week, PrEP remains a very reli­able pro­tec­tion against HIV.

When using around risk:
If you only use PrEP around sex, it is more impor­tant to take your pills on time. The same rule as above applies: take your pill up to 12 hours after you should have tak­en it. You then take the next pill accord­ing to the orig­i­nal sched­ule (that is, 24 and 48 hours after tak­ing the first two pills).

If you for­got the pills before sex or you for­got mul­ti­ple pills, you are NOT SUFFICIENTLY PROTECTED against HIV.

In this case, you should con­tact your GGD or hos­pi­tal, and dis­cuss if you need a PEP treat­ment. Click here for more infor­ma­tion about PEP.

Do I always need to take PrEP at the exact same time?

YES, you should take PrEP at approx­i­mate­ly the same time every day.
But the exact time is not so impor­tant. You can also take your PrEP a few hours ear­li­er or lat­er than planned, and it will still be very effec­tive. There are many apps avail­able to remind you to take your PrEP (via push noti­fi­ca­tions), you can make good use of these!

Can I use PrEP I got from someone else or a dealer at a (sex) party?

Bad idea, don’t do it!
We advise to only use PrEP with a pre­scrip­tion, through a doc­tor and phar­ma­cy. The most impor­tant rea­son is that you need to be sure that you do not have HIV. If you have HIV and use PrEP, then your HIV virus can become resis­tant against the med­ica­tion in PrEP. This makes your HIV hard­er to treat. Also, you need to use PrEP for at least two days after sex; this is the only way you are pro­tect­ed against HIV infec­tion. Those pills are usu­al­ly not avail­able at a (sex) par­ty. Be smart and arrange your PrEP ahead of time, through a doc­tor.

If my sexual partner takes PrEP, am I also protected against HIV?

If your part­ner has test­ed HIV-neg­a­tive and uses PrEP cor­rect­ly, the odds are very low that he can infect you with HIV. We still do not rec­om­mend using this as a method of pro­tec­tion against HIV, because it requires you to trust your sex­u­al part­ner com­plete­ly. A bet­ter strat­e­gy is to pro­tect your­self by also get­ting on PrEP your­self!

What is the difference between PrEP and PEP?

PrEP are pills you take BEFORE being at risk for HIV. PEP is a treat­ment for AFTER being at risk for HIV. For exam­ple, if you had sex with­out con­doms or PrEP with a part­ner whose HIV sta­tus you do not know, you are at risk for HIV. If so, you can get a PEP treat­ment for the first 72 hours after the sex through your GGD clin­ic or hos­pi­tal, to pre­vent you from get­ting HIV. Click here for more infor­ma­tion about PEP.

What does PrEP do to your bones?

In some peo­ple who use PrEP for a long time, bone strength can decrease. In the­o­ry, this can put you at a slight­ly high­er risk for bone frac­tures, but this hasn’t been defin­i­tive­ly proven. Since this is a side effect that only caus­es a prob­lem after using PrEP for years, it is not test­ed for ini­tial­ly. Also, the effect is lim­it­ed: by com­par­i­son, smok­ing cig­a­rettes would prob­a­bly have a larg­er effect. If you already have osteo­poro­sis, dis­cuss with your doc­tor if PrEP is appro­pri­ate for you.

My anus started bleeding during sex, does PrEP still work sufficiently?

PrEP works on the cells deep inside your body. Even if you get skin lesions dur­ing sex or expe­ri­ence anal blood loss, PrEP still works equal­ly well.

Is an HIV test less reliable if you are on PrEP?

HIV tests that are per­formed in a lab­o­ra­to­ry are equal­ly reli­able for peo­ple who use PrEP com­pared to peo­ple who do not use PrEP. With rapid HIV-tests it can take longer to detect a poten­tial ongo­ing HIV infec­tion. We rec­om­mend you to get a reg­u­lar HIV test, and not just a rapid HIV-test.

Swallowing cum, how big it the chance of getting HIV?

The chances of get­ting HIV from swal­low­ing cum are very low. When HIV gets to your stom­ach it is killed instant­ly by the acids in your stom­ach. If you only have oral sex it is not nec­es­sary to use PrEP.

Does it make a difference if you have anal or vaginal sex?

PrEP takes a longer time to pen­e­trate the vagi­nal wall. If you’re hav­ing recep­tive vagi­nal sex, you are there­fore advised to take 1 pill per day for 7 days before sex, and then con­tin­ue tak­ing 1 pill every day.
If you want to stop using PrEP, make sure to take the last pill 7 days after the last time you had sex.

Is PrEP less effective if you have an STI?

In sev­er­al research tri­als that test­ed PrEP, peo­ple who used PrEP reg­u­lar­ly had STD’s. PrEP also worked remark­ably well for these peo­ple.

Is PrEP 100% reliable?

Out of tens of thou­sands of peo­ple who use PrEP world­wide, less than 10 peo­ple are known to have con­tract­ed HIV while using PrEP cor­rect­ly. There is a very small chance that PrEP does not pro­tect you well. This is also why you need to get test­ed for HIV reg­u­lar­ly when you are on PrEP. If you con­tract HIV, this can be treat­ed quick­ly and well. HIV infec­tions did occur in the PrEP research tri­als with peo­ple who did not use their PrEP cor­rect­ly, or for­got to use it. PrEP only works if you actu­al­ly take the pills in the cor­rect way!

Do drugs, alcohol or Viagra change the effectiveness of PrEP?

Using alco­hol, drugs or Via­gra does not change the effec­tive­ness of PrEP. It is pos­si­ble that XTC has an increased effect at the dos­es you were used to before using PrEP. If you com­bine PrEP and XTC, use a small­er dose of XTC the first time, to see how it goes.

Oth­er med­ica­tions (from the phar­ma­cy or drug­store) some­times can­not be used togeth­er with PrEP. Always dis­cuss with your doc­tor if you use oth­er med­ica­tions, to see if it goes togeth­er with PrEP.

Why test for HIV when using PrEP?


It is enor­mous­ly impor­tant that you do not have HIV when you start PrEP. The med­ica­tions in PrEP are used in com­bi­na­tion with oth­er med­ica­tions to treat HIV. If you use PrEP but already have HIV, then your HIV is only treat­ed part­ly, and you are at risk that your HIV becomes resis­tant against the med­ica­tion in PrEP. This makes your HIV treat­ment more dif­fi­cult and may lead to you trans­mit­ting HIV to some­one else, even some­one who uses PrEP. Get test­ed for HIV every 3 months. Read more about HIV here.

Why test the kidney function when using PrEP?

In rare cas­es, PrEP can lead to a decrease in kid­ney func­tion. You won’t notice that your kid­ney func­tion is dete­ri­o­rat­ing until it is too late. This is why you need to get your kid­ney func­tion checked, both before and dur­ing use of PrEP. If your kid­ney func­tion gets worse because of PrEP, stop using PrEP, and your kid­ney func­tion will recov­er. Get your kid­ney func­tion test­ed every 3 months.

Why test for chlamydia, gonorrhea, syphilis when using PrEP?

PrEP only pro­tects against HIV, so you can still con­tract oth­er STDs, some­times with­out notic­ing it. By treat­ing these STDs prompt­ly, you ensure that they are not trans­mit­ted to oth­er sex­u­al part­ners. If every­one gets test­ed for STDs every 3 months, then few­er STDs will go around, and the risk of get­ting an STD will decrease for every­one. Read more about STD’s here.

Why test for Hepatitis C when using PrEP?

Hepati­tis C occurs more often with peo­ple who use PrEP. There is no vac­ci­na­tion against Hepati­tis C, but there is a treat­ment. If a test shows that you have Hepati­tis C, make sure you get treat­ed quick­ly. This is good for your own health, and pre­vents you from trans­mit­ting the virus to your part­ners. Read every­thing about Hepati­tis C here, includ­ing how to make the risk of infec­tion as low as pos­si­ble.

Why test for Hepatitis B before starting PrEP?

Most men are vac­ci­nat­ed against Hepati­tis B, or have acquired immu­ni­ty because they had the virus and their own immune sys­tem has killed it. In rare cas­es, the virus stays in the body: this is called chron­ic Hepati­tis B. In this case, you can only use PrEP dai­ly. PrEP is also a treat­ment for Hepati­tis B, and you should ask your doc­tor before you stop tak­ing PrEP. Before start­ing PrEP, you need to get test­ed for Hepati­tis B once. If you have not been vac­ci­nat­ed yet, make sure to get this done as soon as pos­si­ble. This is free at a GGD STD clin­ic. Read more about Hepati­tis B here.
