UK Drugs in Lactation Advisory Service

UKDILAS breastmilk

What's New?


Guidance on this new antidepressant added to the database.

General breastfeeding guidance

The risks of exposing an infant to a drug via breast milk can be minimised by both health professionals and mothers if some general principles are followed. This guidance should be followed whenever a medicine is being considered for a mother who is breastfeeding her infant, whether the medicine is prescribed or purchased over-the-counter.

It must also be stressed that the general guidance, and the information provided for individual drugs in the accompanying database, only applies to full-term, healthy infants. Additonal care must be taken, and advice sought, if the infant is pre-term or has compromised health at birth.


Enquiries from healthcare professionals can be made by contacting one of the UKDILAS centres below:

Alternatively, submit an enquiry via the online enquiry form and your query will be answered as soon as possible.
