Culture Bound Assumptions in Behavior Intention Models.] abstract - Many models of consumer behavior include fundamental assumptions which are rarely questioned.
PrEP is a course of HIV drugs taken by HIV negative people before sex to reduce the chance of getting HIV. Results in trials have been very successful, with PrEP significantly lowering the risk of becoming HIV positive and without major side effects.
The truth is that PrEP comes with risks. Truvada can cause stomach upset in the first weeks of taking it. The drug, though low on side effects as HIV meds go, has been linked to mild kidney and bone problems in a small percentage of HIV-positive takers.
