RxNT offers THOMAS users an integrated web and PDA product that gives health care providers of all sizes a flexible solution. RxNT does more than just let you send your prescriptions electronically, it will also assist both you and your patients in the selection of generic drugs (when possible), monitoring for drug interactions, and allowing you to see what other providers have prescribed for your patients.
