SIG Code Decoder
Prescription directions use short codes such as bid, po, and qhs. Type or paste a SIG and the tool expands each code into plain English.
It can also show the expanded line in French, Punjabi, Chinese, or Korean. The phrase list covers common label instructions only.
The tool expands text. It does not check whether a dose is correct.
The expanded direction appears here.
Data: the SIG abbreviation dictionary in src/lib/sig-codes.ts and the label phrase table in src/lib/label-translation.ts. Both ship in the PharmFlow prescription workflow.
Common questions
Does this tool check that a direction is safe?
No. It expands abbreviations into plain text. A pharmacist must still review the prescription.
Which abbreviations does it know?
Common SIG codes for dose forms, routes, frequency, meals, and instructions. It also expands patterns like q4h and x7d.
Does anything I type leave the browser?
No. The expansion runs on your device. The page makes no network call.
