Avatrombopag

Likely Compatibility

Fairly safe. Mild or unlikely adverse effects. Compatible under certain circumstances. Follow-up recommended. Read Commentary.

Avatrombopag is a non-peptide agonist of the thrombopoietin receptor that causes an increase in platelet production. Indicated for the treatment of severe thrombocytopenia in patients with chronic liver disease who are scheduled for invasive procedures and for the treatment of chronic primary immune thrombocytopenia that does not respond to other treatments. Oral administration.

At the time of the last update, we found no published data on its excretion in breast milk.

Its pharmacokinetic data (very high volume of distribution and percentage of plasma protein binding, and moderately high molecular weight) make it very unlikely that it will pass into breast milk in clinically significant amounts.

Alternatives

We do not have alternatives for Avatrombopag.

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.
