Common Abbreviations
 qd or od = every day
 po = by mouth (orally)
 qod = every other day
 IV = intravenous
 bid = twice daily
 IV push or bolus = at one time
 tid = thrice daily
 IV infusion = infuse over time
 qid = four times/day
 IM = intramuscular
 ac = before meals
 stat = immediately
 pc = after meals
 sq or sc = subcutaneous
 hs or qhs = at bedtime
 sig = signa or signetur =
 disp = dispense
 prn = as needed
directions for use
 Qod and qid can get mixed up; qod and qd can get
mixed up.
 One solution is to write out “once a day” or “once every
other day” or “four times daily.”
 This brings up the confusion between q6h and qid.
 Does this medication require a strict 6-hour dosing
interval?
 Or, can it be given four times daily, for example, in a
6:30 AM to 11:00 PM day?
Telephone Orders
 Telephone orders may be placed for drugs in Schedules III, IV, and V.
 A written prescription is required for ordering drugs in Schedule II.
 In an emergency, a prescription for Schedule II drugs may be telephoned to
a pharmacy. If the pharmacy is willing to accept the telephone order, only
enough drug to cover the emergency may be prescribed. The physician is
then required to supply a written prescription to the pharmacy within 72
hours. The pharmacist is required to call the "Feds" if he doesn't receive the
prescription within 72 hours.
 "Emergency" means that the immediate administration of the drug is
necessary to proper treatment, that no alternative treatment is available,
and that it is not possible for the physician to provide a written prescription
order for the drug at that time.
Risk Management Strategies for Prescribers
 BE PROFESSIONAL AND COURTEOUS
 KEEP GOOD RECORDS
 PROVIDE ADEQUATE AND INFORMED CONSENT
 TELL AND ALLOW PATIENTS TO CALL WHEN NECESSARY
 PROVIDE THE PATIENT WITH A REALISTIC ASSESSMENT OF
OUTCOME, BENEFIT, AND ADVERSE REACTIONS
 DO NOT SUPPORT FALSE EXPECTATIONS
