Antiretroviral Medication Use

Antiretroviral medications are used to prevent transmission of HIV in cases of blood borne pathogen exposures. Antivirals kill a vius or suppress its ability to replicate.

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

If you sustain a needlestick you may be prescribed 2 medications: Truvada and Isentress.

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.

Isentress (400mg)

HIV-1 integrase strand transfer inhibitor that is taken twice daily. It contains raltegravir.
