Purpose of App Review

  • Does the NIH mobile resource on lactation information really help breastfeeding mothers understand their drug intake effects on infants?


LactMed is an app developed and maintained by the National Institutes of Health (NIH) and offers dependable information for lactating mothers.

The app contains evidence-based references on how certain drugs taken by a woman present themselves in breast milk, and how these drugs may affect or impact an infant’s well-being.

The mobile app is also available online via TOXNET.

It also contains suggestions to alternative drugs and drug classes for mothers to make more informed decisions about their medication intake while breastfeeding. Along with recommended drugs and supplements, LactMed provides information about safe maternal and infant drug levels as well.

User Interface

To help users navigate the resource, LactMed offers two simple access points from the app homescreen:

  1. Drug Name Search
  2. Drug Class Search

Searching by drug name contains an alphabetical list to choose from to either scroll or manually enter a medication name. Both options work well and the interface is intuitive for users of any comfort level. This option should be used when users know the exact name of a drug/supplement they are taking or considering taking.

The drug class search option is equipped with the same functionality as the drug name search, but it displays the information a bit more generally. Searching for a drug class should be utilized if users are unsure of a specific name of a medication/supplement, but are aware of the type of drug it falls under (e.g. narcotics, analgesics, anesthetics, anti-infective agents, etc.).

From any screen within LactMed, users can get to a General Info section. This section details where the data in the app is coming from as well as information on the NIH and TOXNET. Also, the app contains interoperable navigating between search functions by easily allowing users the option to switch from drug name search to drug class search, and vice versa. The design of information and sections in a LactMed drug record is superbly done and understandable. Users shouldn’t have a problem finding effects information and linking out to PubMed articles to read more.
