ut dict stands for Ut dictum (as directed), a prescription abbreviation.

Latin instruction meaning the patient should take or use the medicine as previously explained. Pharmacists dislike it because the label then gives no dosing information, and insurers cannot calculate a days' supply.

Example: Prednisone 10 mg tabs #21, ut dict per taper sheet.

Usage notes

Also written ut dict. or u.d. ISMP lists the related form "UD" as error-prone because it can be read as "unit dose". Most pharmacies will call the prescriber to obtain explicit directions rather than print "use as directed", especially for tapering regimens like prednisone, where a dosing error is easy.
