This list, containing about 750 medicament’s, is specifically developed for mothers and professionals. If you are in need of a ‘usually safe’ or ‘not safe’ medicine, check with your doctor and show him the list for professionals.
Paediatrician Erica Post compiled this list [third version], based on the latest book of Thomas Hale [2008] and the latest recommendations of the American Academy of Paediatrics [2001]. This third update and translation was facilitated by the Kenniscentrum Borstvoeding with the help of Stefan Kleintjes, dietician, in September 2008 and June 2009.

Explanation for users
The medicaments in this list are ordered alphabetically and we have used the therapeutic moiety of the medication as it’s name. For example Valium is named Diazepam. Valium is a brand name for Diazepam.
Furthermore, the list contains, apart form the name of the medication and its function, the advice of Thomas Hale [L1 – L5] and the advice of the AAP. The information in the fifth column is used for attentions, not listed in the other columns, but things to remember. For example, antibiotics can cause Candida-infection.
The advices of Dr. Thomas Hale, pharmacologist
Thomas Hale’s advices are listed in the third column. Hale updates his advices every two years [last update 2008]. His advices are based on all known pharmokinetic aspects important for breastfeeding mothers and their baby’s. Hale’s information is also based on the most recent published scientific articles. Based on this information he determines the lactation risk category.
Thomas Hale lactation risk categories:
- L1 Safest
- L2 Safe
- L3 Moderately safe
- L4 Possibly hazardous
- L5 Contraindicated
Drug which has been taken by a large number of breastfeeding mothers without any observed increase in adverse effects in the infant. Controlled studies in breastfeeding women fail to demonstrate a risk to the infant and the possibility of harm to the breastfeeding infant is remote; or the product is not orally bio-available in an infant.
Drug which has been studied in a limited number of breastfeeding women without an increase in adverse effects in the infant. And/or the evidence of a demonstrated risk which is likely to follow use of this medication in a breastfeeding woman is remote.
There are no controlled studies in breastfeeding women, however, the risk of untoward effects to a breastfed infant is possible; or, controlled studies show only minimal non-threatening adverse effects. Drugs should be given only if the potential benefit justifies the potential risk to the infant. New medications that have absolutely no published data are automatically categorized in this category, regardless of how safe they may be.
There is positive evidence of risk to a breastfed infant or to breast milk production, but the benefits from use in breastfeeding mothers may be acceptable despite the risk to the infant, e.g. if the drug is needed in a life-threatening situation or for a serious disease for which safer drugs cannot be used or are ineffective.
Studies in breastfeeding mothers have demonstrated that there is significant and documented risk to the infant based on human experience, or it is a medicament that has a high risk of causing damage to an infant. The risk of using the drug in breastfeeding women clearly overweighs any possible benefit from breastfeeding. The drug is contraindicated in women who are breastfeeding an infant.
The advices of the American Association of Paediatrics [AAP]
The American Association of Paediatrics [AAP] also gives advice about medication and breastfeeding. Their information has a different categorizing and they have less information than Thomas Hale. When Hale and the AAP do not agree, Hale is usually stricter. For example, when medication has a bad influence on the quantity of milk, Hale lists this as negative while the AAP doesn’t. The advices of the AAP are listed in the fourth column.
