Sino-implant (II)® continuation and effect of concomitant tenofovir disoproxil fumarate-emtricitabine use on plasma levonorgestrel concentrations among women in Bondo, Kenya

In particular, reproductive-aged women at high risk of HIV are in need of highly effective methods both to protect themselves against HIV and to prevent pregnancy. This paper provides early data on the effect of Truvada on levonogestrel levels among women using Truvada for HIV prevention and Sino-implant (II) for contraception.
