The effects of supply shortages of HIV medications.

Dear PrEP Users,

Since October 2023 until March 2024, the medication Emtricitabine/Tenofovirdisoproxil (FTC/TDF), which you use as HIV prophylaxis (PrEP), has not been available in sufficient quantities. The supply shortage has now been partially resolved. However, the effects this shortage has had on PrEP users have not yet been systematically recorded. I would like to examine the impact of the supply shortage on access to HIV PrEP as part of my medical doctoral thesis.

We would like to hear your opinions and assessments to understand your situation during that time of medication shortage. Therefore, I kindly ask you to complete the questionnaire. The data will be analyzed anonymously. Thank you for taking the time.
