What does the abbreviation 'qd' stand for in medication instructions?

• A. Every hour
• B. Every day
• C. Every other day
• D. At bedtime

Answer: (B)

Understanding medication instructions involves decoding common Latin abbreviations. qd comes from quaque die, meaning “every day.” So a directive like take this tablet qd means to take one tablet once daily, ideally at the same time each day if a specific time isn’t given. This is different from every hour (qh), every other day (often written qod or q2d), or at bedtime (qhs). Some clinicians now prefer writing it out as “every 24 hours” to avoid misreading, but the intended meaning is daily.
