Antiretroviral Medication Use

Early studies showed an 84% decrease in transmission of HIV when taken as directed for 28 days.

You may be started on the medications until a rapid HIV tests shows the source patient is negative. If the source is unavailable, unwilling, or HIV + you may be told to take the medication for 28 days.
