Propantheline Bromide

Low Risk

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

Propantheline is a quaternary ammonium with antimuscarinic effects similar to those of atropine. It is used to treat urinary incontinence, hyperhidrosis, and bowel and bladder spasms. Oral administration 3 times a day.

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

Intestinal absorption is very low, reaching extremely low plasmatic levels or below the detection limit (Vose 1979), so it is highly unlikely that significant amounts will pass into breast milk.

This very low oral bioavailability, even lower if taken with food, minimizes the passage into plasma of the infant from ingested breast milk, except in the premature and in the immediate neonatal period in which there may be greater intestinal permeability.

Although antimuscarinics can decrease prolactin production (Müller 1983, Masala 1982), once lactation is established, milk production depends more on the repeated stimulation of suckling than on prolactin levels.

Alternatives

  • Otilonium Bromide (Possibly safe. Probably compatible. Mild risk possible. Follow up recommended. Read the Comment.)
  • Oxybutynin (Possibly safe. Probably compatible. Mild risk possible. Follow up recommended. Read the Comment.)

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.
