What are Prescription Abbreviations?

Prescription abbreviations are shorthand notations used by healthcare professionals to communicate dosage instructions efficiently. Derived primarily from Latin, these codes appear on prescriptions, medical records, and medication labels. Understanding them is crucial for patient safety, medication compliance, and avoiding dosing errors. Common abbreviations cover frequency, route of administration, timing, and quantity.

Common Prescription Abbreviations

Essential medical abbreviations every patient should know:

• Frequency: qd, bid, tid, qid

  qd = once daily, bid = twice daily, tid = three times daily, qid = four times daily. Note: 'qd' is often replaced with 'daily' to avoid errors.

• Timing: ac, pc, hs, prn

  ac = before meals, pc = after meals, hs = at bedtime, prn = as needed. Critical for medication effectiveness and reducing side effects.

• Route: po, IV, IM, SC

  po = by mouth (oral), IV = intravenous, IM = intramuscular, SC/SQ = subcutaneous. Determines how medication enters body.

• Quantity: tab, cap, ml, mg

  tab = tablet, cap = capsule, ml = milliliter, mg = milligram. Specifies dosage amount and form.

• Duration: x3d, x7d, x14d

  Duration of treatment - x3d = for 3 days, x7d = for 7 days, x14d = for 14 days. Complete the full course even if feeling better.
