Εφαβιρένζη

Compatible

Safe substance and/or breastfeeding is the best option.

Antiretroviral. It is a non-nucleoside reverse transcriptase inhibitor (NNRTI) with activity against HIV-1 used with other antiretrovirals for combination therapy of HIV infection and AIDS. Oral administration once a day.

It is excreted in breast milk in clinically insignificant amounts. (Aebi 2022, Oumar 2018, Palombi 2016, Olagunju 2015, Schneider 2008)

No problems have been observed in infants whose mothers have taken it. (Kapito 2021, Oumar 2018, Olagunju 2015, Cohan 2015, Schneider 2008

Plasma levels in these infants were very low, 9% to 13% of maternal plasma levels. (Aebi 2022, Oumar 2018, Palombi 2016, Olagunju 2015, Gandhi 2013, Schneider 2008)

Several medical societies and expert authors consider the use of this medication to be safe during breastfeeding. (WHO 2016 y 2014, Pandhi 2014, Hirnschall 2013)

Alternatives

We do not have alternatives for Εφαβιρένζη since it is relatively safe.

Suggestions made at e-lactancia are done by APILAM team of health professionals, and are based on updated scientific publications. It is not intended to replace the relationship you have with your doctor but to compound it. The pharmaceutical industry contraindicates breastfeeding, mistakenly and without scientific reasons, in most of the drug data sheets.

Jose Maria Paricio, Founder & President of APILAM/e-Lactancia

Your contribution is essential for this service to continue to exist. We need the generosity of people like you who believe in the benefits of breastfeeding.

Thank you for helping to protect and promote breastfeeding.
