For example Medicines Q&A’s, Refrigerated Storage, Compliance aid storage in addition to advice on the use during lactation.

To locate information and advice on the use of a medicine during lactation this link takes you to Safety in Lactation area of the SPS website.  Use the Medicine filter on the right hand side to search for a particular medicine.  Click on the medicine name in the grey box, this will then display all the available information for that medicine.  Scroll down the page to Lactation Safety Information.  Within this section there are links to further information, such as the therapeutic group summary, which provides an over view on the use in lactation of that particular therapeutic group of medicines, and relevant Medicines Q & A’s.

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:
