Isoetharine

Likely Compatibility

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

Selective beta-2 adrenergic bronchodilator of similar action to salbutamol, both with similar characteristics to Terbutaline. Inhaled administration.

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

Inhalation absorption is minimal and plasma levels are very low. In addition, its low intestinal absorption makes it difficult to pass into the plasma of the infant from ingested breast milk.

Expert authors consider safe the use of inhaled bronchodilators during breastfeeding due to the low maternal serum levels and low bioavailability. (Hale, Lactmed, Amir 2011, National Asthma 2004, Nelson 2001, Ellsworth 1994)

Alternatives

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.

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.
