Dimetindene Maleate (systemic use)

High Risk

Poorly safe. Evaluate carefully. Use safer alternative or interrupt breastfeeding 3 to 7 T ½ (elimination half-lives). Read the Comment.

First generation antihistamine drug which is derived from ethylene diamine with important sedative and antimuscarinic effects.

At latest update no published data on excretion into breast milk was found.
Inhibition of breastfeeding in the first weeks after birth due to an antiprolactin effect may appear.
For both the mother and the infant it would be safer taking antihistamines with proven safety and without sedative effect, especially in case of premature babies and infants under 1 month of age.

Otherwise when used during lactation, take the lowest effective dose but avoiding a prolonged use. Follow-up the baby for drowsiness and feeding issues.
It is not recommended to share a bed with your baby if you are taking this medicine.

The topical use as a gel or cream is compatible with breastfeeding. Do not apply on the chest. See Dimethindene Maleate (topical).

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.
