FAQ
Why do doctors and pharmacists write in shorthand (Sig)?
Medical practitioners use standard Latin-derived abbreviations (known as the "Sig" or signa) to quickly and concisely convey precise dosage instructions, routes of administration, and timing on prescription pads and electronic health records.
What do BID, TID, QID, and PRN mean?
BID means "bis in die" (twice a day), TID means "ter in die" (three times a day), QID means "quater in die" (four times a day), and PRN means "pro re nata" (take as needed/as necessary).
What is the difference between PO and SL routes?
PO ("per os") means taken by mouth (swallowed with water), whereas SL ("sub lingua") means placed under the tongue to dissolve directly into the bloodstream.
What should I do if I am uncertain about a prescription label instruction?
Always verify medication instructions directly with your dispensing pharmacist or prescribing physician before taking any medication.
