Darunavir (DRV)

Very Low Risk

Safe. Compatible. Minimal risk for breastfeeding and infant.

HIV protease inhibitor antiviral. Used, alone or boosted with Cobicistat or Ritonavir and associated with other antivirals, in the treatment of HIV/AIDS (Navarro 2016). It has been used experimentally in the treatment of coronavirus infection COVID-19 (SEFH 2020). Oral administration in one or two daily doses.

It is excreted in breast milk in clinically insignificant amounts (Aebi 2022) and no problems have been observed in infants whose mothers took it. (Prestile 2022)

The plasma levels of these infants were very low or below the limit of detection. (Aebi 2022)

Possible side effects are rare and, in general, of mild-moderate severity: diarrhoea, nausea, rash,... (Navarro 2016)

"Individuals with HIV who are on ART with a sustained undetectable viral load and who choose to breastfeed should be supported in this decision". (Panel 2022 p ix)

We do not have alternatives for Darunavir (DRV) 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.
