Safe substance and/or breastfeeding is the best option.

Synthetic analog of dinoprost (prostaglandin F2-alpha).
Indicated in the treatment of ocular hypertension and glaucoma.
Topical administration in the form of eye drops, one drop a day.

At the date of the last update, the authors did not find published data on its excretion in breast milk.

Its pharmacokinetic data (moderately high molecular weight, high percentage of protein binding, very short half-life and high pKa) make it unlikely that significant amounts will pass into breast milk (Belkin 2020, Blumen 2020).

Its null oral bioavailability makes it difficult for it to pass to the infant plasma from ingested breast milk, except in premature infants and in the immediate neonatal period in which there may be greater intestinal permeability.

The absorption should be minimized by pressing the tear duct (inner corner of the eye) with the finger for 1 to 5 minutes and administering the dose immediately after a breastfeed (Belkin 2020, Méndez 2012).


  • Acetazolamide (Safe substance and/or breastfeeding is the best option.)
  • Timolol Maleate (Safe substance and/or breastfeeding is the best option.)

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.
