Persistence of nevirapine in breast milk after discontinuation of treatment.

ABSTRACT

The objective of this study was to serially quantitate the concentration of nevirapine in breast milk after discontinuation of treatment. Samples were collected from both breasts of a human immunodeficiency virus-infected patient for 3 weeks. Nevirapine was quantifiable for up to 17 days after discontinuation of therapy; total nevirapine concentrations remained above the 90% inhibitory concentration for 6 days, and no differences were observed between breasts.
