Glycerol Phenylbutyrate; Sodium Phenylbutyrate

Low Risk

Possibly safe. Probably compatible. Mild risk possible. Follow up recommended. Read the Comment.

It is a drug that decreases elevated plasma levels of glutamine and ammonium in patients with urea cycle disorders. Oral administration before meals.

Since the last update we have not found published data on its excretion in breastmilk.

Its rapid metabolism to phenylacetate and short elimination half-life make it highly unlikely that clinically significant amounts will pass into breast milk.

It is a medication for use since the neonatal period.

With the correct dosage, side effects are not frequent or serious. The possibility of breastfeeding will depend more on the underlying disease and the clinical status of the mother.

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.
