Culture Bound Assumptions in Behavior Intention Models.] abstract - Many models of consumer behavior include fundamental assumptions which are rarely questioned.
Pre-exposure prophylaxis (PrEP) is a course of HIV drugs taken daily by HIV negative people most at risk of HIV to reduce their risk of HIV infection. Truvada is currently the only drug approved for use as PrEP. Truvada is a single pill that is a combination of two anti-HIV drugs, tenofovir and emtricitabine.
Some people are using PrEP by getting NHS prescriptions for PEP. (PEP is where the NHS prescribes one month of HIV meds after a high risk exposure). Some doctors recommend patients buy generic drugs until the government decides whether PrEP will be available in the health system.
