[Users' Adherence and Off-Label Use of HIV-Pre-Exposure Prophylaxis].

INTRODUCTION

HIV-PrEP (HIV-Pre-Exposure Prophylaxis) has been available through German pharmacies in various package sizes since 2017. It can be used for daily dosing or as an intermittent product used as required.

AIM: The aim of this survey was to record socio-demographic basic characteristics, the respondents' medical history regarding STI (sexual transmitted infections), previous PEP (Post-exposure prophylaxis) use, the system of PrEP use, the prior diagnostics carried out as well as the advice regarding the use of PrEP and information on whether PrEP was passed on to others.

METHOD: A cross-sectional analysis was carried out in the form of a revised, self-developed multiple-choice questionnaire for 515 users within the network of HIV-competent pharmacies.

RESULTS

Three-quarters of the exclusively male respondents were in the age group of 20-39 years. More than 80% used the PrEP according to recommendations. Approximately two-thirds had received PEP in the past. The same number also had, at least, one STI in previous years. The necessary previous diagnostics were mostly carried out; 7% of the PrEP is passed on to other users.

CONCLUSION

The majority (approximately 2/3) of the PrEP users are high-risk users with regard to previous STI or previous PEP use, and use the PrEP according to recommendations. As a result of simpler prescribability and broader use, the importance of PrEP is expected to grow in future.
