OBJECTIVE： To provide suggestions for improving pediatric medication information in drug instructions of microecological preparations in China. METHODS： Using text analysis method， the pediatric medication information in the instructions of 36 approval number of microecological （29 varieties from 23 enterprises） is statistically analyzed. RESULTS： Among the 36 microecological preparations， there were 2 medicines for children （5.56％）. There were 2 granules （5.56％）， 9 dispersants （25.00％）， 9 tablets （25.00％） and 16 capsules （44.44％）； there were 6 national essential medicines （16.67％）； there were 13 products in the list of national essential medical insurance （36.11％）； there were 22 OTC products （61.11％）. The proportion of children’s indications， children’s usage and dosage， child-related adverse reactions， taboos and matters needing attention in the drug instructions for children were 19.44％， 55.56％， 2.77％， 5.56％ and 8.33％， respectively. The proportion of specific information about children’s drug use marked in the item of  “children’s drug use” was 25.00％. CONCLUSIONS： There is a lack of information on pediatric medication in the instructions of microecologial preparations in China， and there are some problems such as unclear wording， scattered labeling position of the medication information for children， and the content is not practical. It is recommended that medical institutions should strengthen the rational use of medical guidance for medical personnel， implement the scientific management process of over-instruction medications； the relevant departments should introduce more incentive policies， encourage enterprises to improve the basis of children’s medications， and make standardized labeling of children’s medication information in drug specifications. In addition， a database of information on children’s medications can be established to provide a reference for rational use of pediatric drugs.
