The following discussion of medication categories, which includes drugs used in cardiology and general practice, will help pharmacists and other healthcare professionals understand which drugs are the optimal choices within specific categories for breast-feeding mothers to take while minimizing the impact on in-fants. Ambulatory care medications and analgesics and anesthetics were discussed in Part I of this 3-part series. 1 Objective: To provide a guide for practicing pharmacists, pharmacy technicians, and other healthcare professionals so that they are able to counsel and advise breast-feeding mothers and fellow healthcare professionals on the safety and use of common cardiology and general medications during breast-feeding.Data Sources: Primary texts used by the breast-feeding community (Medications and Mothers' Milk, Drugs in Pregnancy and Lactation, Drugs and Human Lactation) were searched, as well as Micromedex, MEDLINE, PubMed, EMBASE, and EMBASE2 (1984( -February 2004.
Study Selection/Data Extraction:Multiple sources were used wherever available to validate the data, and primary articles were used to verify all tertiary source information. Search terms included breast-feeding, lactation, nursing, and medications, as well as specific drug names.Data Synthesis: Concerns regarding medication use during breast-feeding have caused mothers to either discontinue nursing or not take necessary medications. Complete avoidance of medications or cessation of breast-feeding is often unnecessary. Although there are drugs that can be harmful to nursing infants, breast milk concentrations of most drugs are insufficient to cause any harm.
Conclusions:Having objective and reliable information on medications enables pharmacists, pharmacy technicians, healthcare providers, and mothers to make educated decisions regarding drug therapy and breast-feeding.
