In the clinical report, Dr. Sachs indicates that this cautious approach may not be necessary because only a small number of drugs are contraindicated in breastfeeding and may cause adverse side effects to the infant.
The use of narcotics including codeine, hydrocodone, and oxycodone are discouraged. The report also found that alcohol, amphetamines, benzodiazpines, cocaine, heroin and LSD are drugs of abuse for which adverse effects on the breastfeeding infant have been reported.
This report also looked at some herbal supplements for nursing mothers. However, there is a lack of data on safety and efficacy for many supplements. Some herbal supplements should not be used such as kava kava due to its "association to severe liver damage". Another herbal supplement that should not be used is yohimbe because of "reports of associated fatalities in children." St. John's wort is another herbal supplement as "it may cause colic, drowsiness or lethargy in breastfed infants."
