Interesting information about taking PrEP
What is PrEP (Pre-exposure prophylaxis)?
HIV PrEP (Pre-exposure prophylaxis), also known as PrEP medication, is the administration of HIV antiretroviral drugs to individuals who are not HIV-infected before engaging in high-risk behaviors to reduce the chances of infection from infected individuals. In Thailand, the medication consists of two drugs in a single pill: Tenofovir (TDF) 300 milligrams and Emtricitabine (FTC) 200 milligrams.
There are approximately 650,000 PrEP users worldwide, and it is highly popular in many countries due to its effectiveness in preventing HIV infection. However, in Thailand, there are relatively few users, estimated at only around 12,000 people, due to limited access to the medication and insufficient dissemination of information. Additionally, the cultural attitudes of Thais may deter at-risk individuals from seeking consultations.
How effective is PrEP in preventing HIV infection?
Pre-exposure prophylaxis (PrEP) is highly effective in preventing HIV infection from sexual intercourse, with an efficacy of up to 99% when taken correctly. It also demonstrates efficacy in preventing infection among people who inject drugs, estimated at around 74%.
