Of course, an existing HIV infection must be ruled out before PrEP is used; a detailed risk assessment and counseling is required, and HIV progress checks are performed every three months. <br><br>In Switzerland, PrEP has so far been used almost exclusively by men who have sex with men. A distinction is made between two types of intake*: <\/p>\n\n\n\n<ul class=\"wp-block-list\" id=\"block-25abcb32-2cd2-4795-9977-86a762ea5eba\">\n<li>&#8220;Continuous PrEP&#8221; begins seven days before the first time you have sex without a condom and is taken daily during the period of unprotected sex and for another 7 days after the last unprotected sex, and only then is it stopped.<\/li>\n\n\n\n<li>In \u201cOn-Demand PrEP,\u201d two PrEP tablets are taken 2 to 24 hours before the first unprotected sex, then one tablet daily at the same time (+\/\u2013 2 hours), and one tablet each day for 2 days after the last unprotected sex.<\/li>\n<\/ul>\n\n\n\n<p><\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"block-27ab9145-38c0-4622-82a2-07df9f1d5805\">New data on the use and safety of the &#8220;On-Demand-PrEP&#8221;<\/h2>\n\n\n\n<p id=\"block-5c8ed008-5a04-43f6-b27d-0b9858f59f35\">For the &#8220;On-Demand-PrEP&#8221; it says on www.myprep.ch: &#8220;Although the data situation so far looks good, there are not yet as many studies for this intake scheme as for the permanent PrEP.&#8221;<br><br>It is good to speak such a word of caution. On the other hand, new data is constantly being added to the On-Demand PrEP. For example, updated data from the Prevenir study (France) and the Belgium national surveillance results (2017\u201318) were presented last week at the European AIDS Conference in Basel**. Observation of nearly 3000 PrEP users in France and about 2400 individuals in Belgium showed adherence as on-demand PrEP in nearly 50% in both countries. When performed correctly, no failure with newly acquired HIV infection was found with either continuous PrEP or On-Demand PrEP.    <br><br>The final evaluation of both studies is still pending. Even if this information is just another building block of knowledge: They help to further consolidate the assessment of the &#8220;99% effectiveness*&#8221; of the On-Demand-PrEP as well. <\/p>\n\n\n\n<p id=\"block-7504c20a-4fb1-40cb-b33b-2338fa043ef7\"><em>*quote adapted from <a href=\"http:\/\/myprep.ch\/\">www.myprep.ch**<\/a><\/em><\/p>\n\n\n\n<p id=\"block-8faa5432-60d3-4f93-9bae-1af4a50700d8\"><em>Lectures 11\/8\/19, PS11:<\/em><\/p>\n\n\n\n<p id=\"block-2715cd1f-5adc-438a-87c7-3eca5e29928a\"><em>Dominique Costagliola, &#8220;PrEP persistence and associated factors: ananalysis from the ANRS Prevenir study.&#8221;<br>Jessica Deblonde, &#8220;Monitoring PrEP implementation in Belgium: nationalsurveillance results, 2017-2018.&#8221;<\/em><\/p>\n\n\n\n<p>\ufeff<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Brief introduction to PrEP PrEP (pre-exposure prophylaxis) is taking two HIV medications (combined in one tablet) to protect against HIV infection.
