Teratogens, pregnancy, pharmacists, drug information


We report on the first Helpline for pharmacists dealing with the safety of medications in pregnancy and during breastfeeding. Pharmacists from all parts of Canada participated in this pilot, receiving guidance in approximately 90% of cases. There were 472 inquiries relating to 598 products with regards to safety in pregnancy and 197 calls relating to 249 products regarding exposure in breastfeeding. All callers who were surveyed found the service helpful in counseling both patients and physicians.
