Antiretrovirals have significant risks and adverse effects. Uninfected people don't take antiretrovirals unless they have been exposed to the virus. They protect against exposure instead. The chance of both condoms and antiretroviral therapy failing to prevent transmission simultaneously is always going to be lower than the chance of either failing independently. In practice, many couples decide that the risk of transmission associated with antiretroviral therapy is low enough for them.
