Brief Summary:

Taking antiretrovirals once-a-day is considered the simpler way to improve adherence. However, it is not know if this assertion apply to patients taking their medication twice-a-day who change to once-a-day.

We hypothesized that once-daily dosing improves adherence.


Condition or disease Intervention/treatment Phase
HIV Infections Behavioral: Nevirapine from twice-a-day to once-a-day Phase 4
