Understanding "q week" in Medical Orders

q week (or q.wk) is a medical abbreviation from Latin quaque hebdomada, meaning "every week."

Usage

  • Medication orders: "Take 1 tablet q week."
  • Treatment schedules: "Infusion q week x 6 weeks."
  • Follow-up: "Return visit q week."

Related Abbreviations

  • q.d. / qd = daily (quaque die)
  • b.i.d. / bid = twice daily (bis in die)
  • t.i.d. / tid = three times daily
  • q.o.d. = every other day
  • q.h. = every hour

Always clarify ambiguous orders; "qw" can be confused with "q.w." (every week) vs. "q.wk." Standardize per institutional policy.
