High Risk

Poorly safe. Evaluate carefully. Use safer alternative or interrupt breastfeeding 3 to 7 T ½ (elimination half-lives). Read the Comment.

It is an HIV protease inhibitor with antiviral activity against HIV. It is used in the treatment of HIV infection and AIDS. Administration together with other oral antiretrovirals in three daily doses.

It is excreted in breast milk in unknown concentration, but between one and five times higher than plasma. (Colebunders 2005)

The most frequent side effects are gastrointestinal disorders (abdominal pain, diarrhea, nausea and vomiting), headache, dizziness and nephrolithiasis and renal failure.

During lactation other HIV/AIDS treatments are preferable. (Panel 2022, WHO 2016)

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.
