Very Low Risk

Safe. Compatible. Minimal risk for breastfeeding and infant.

Alcaftadine is a histamine H1-receptor antagonist for ophthalmic use to prevent itching associated with allergic conjunctivitis in adults and children from 2 years of age. Topical administration once daily as eye drops.

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

It reaches peak plasma concentrations of less than 120 pg/ml (Bohets 2011, Allergan 2011), so passage into milk must be negligible.

The small dose and low plasma absorption of most topical ophthalmic preparations make passage of significant amounts into breast milk unlikely.

For ophthalmic administration, absorption can be minimised by pressing the tear duct (inner canthus of the eye) with the finger for 1-2 minutes and administering the dose immediately after breastfeeding. (Belkin 2020, Blumen 2020)


We do not have alternatives for Alcaftadine 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.

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.
