The Drug Portal touches on all related information resources at NLM to provide for a comprehensive view.It is intended as a "middle ground" resource which includes information for the consumer, health professionals, and researchers.

  • Pillbox

    Developed to aid in the identification of unknown solid dosage pharmaceuticals, Pillbox combines high-resolution images of tablets and capsules with appearance information (imprint, shape, color, etc.). It enables users to identify solid dosage forms based on physical criteria: imprint (characters or number printed on a medication), shape, color, size, and scoring. Users are shown thumbnail images of possible matches. These images are continually updated as the user enters additional information. Pillbox is designed for use by emergency physicians, first responders, other health care providers, Poison Control Center staff, and concerned citizens.

  • RxNorm

    RxNorm provides normalized names for clinical drugs and links its names to many of the drug vocabularies commonly used in pharmacy management and drug interaction software, including those of First Databank, Micromedex, MediSpan, Gold Standard Alchemy, and Multum.

  • LactMed

    The database Drugs and Lactation, or LactMed, responds to the increased prevalence of breastfeeding worldwide. Drugs in breast milk pose a potential risk to the breast-fed infant, and LactMed provides healthcare practitioners and nursing mothers with data and information on drugs to which breastfeeding mothers may be exposed, and the effects of those agents on nursing infants and on lactation. LactMed contains about 1,000 records on drugs, herbals and dietary supplements that also include a summary regarding use of the specified substance during lactation, potential alternative medications, and references that are linked to their respective PubMed records. LactMed is endorsed by the American Academy of Pediatrics.
