Calls to a Major Teratogen Information Service Regarding Exposures During Breastfeeding

摘要

Background: MotherSafe is a free telephone-based counseling service for Australian consumers and health care providers concerned about drug exposures during pregnancy and breastfeeding. Calls relating to breastfeeding are relatively common and a source of significant distress to the breastfeeding mother, particularly if there is a lack of clarity regarding possible adverse effects of drug exposure on the infant. This study seeks to identify the medication exposures of concern for breastfeeding mothers and the information available to address these concerns. Aims: To review calls to MotherSafe about breastfeeding drug exposures during the 19-year period from 2000 to 2018 and to highlight drugs of concern and counseling issues. Materials and Methods: A retrospective descriptive assessment of a prospectively collected Access database was undertaken. Phone counseling records identified the medication (and other) exposures of concern regarding breastfeeding. The information about medication exposures via breastfeeding provided in consumer and product information (PI) was also reviewed. Results: Of a total of 315,158 calls received at MotherSafe between 2000 and 2018, 116,876 (37.1%) were regarding drug exposure via breastfeeding; 30% of these calls related to nonsteroidal anti-inflammatory drugs, antihistamines, antidepressants, simple analgesics, and antibiotics, and 5% were regarding an exposure specifically contraindicated when breastfeeding. Conclusions: Queries about medication exposures via breastfeeding represent a significant proportion of all the counseling calls to MotherSafe. This study demonstrates the inconsistent and often misleading information about breastfeeding exposures found in consumer and PI sheets and online and highlights the important role of Teratogen Information Services like MotherSafe in providing evidence-based information to both consumers and health care providers.
