What does BID indicate in a prescription?

• A. Twice daily
• B. Three times daily
• C. Once daily
• D. Every hour

Answer: (A)

Dosing frequency indicated by BID means the medication should be given twice a day, roughly every 12 hours. It comes from the Latin bis in die, guiding you to space doses across the day so drug levels stay more consistent and reach therapeutic effect without large peaks. In practice, this is often morning and evening (for example, around 8 AM and 8 PM) to fit typical daily routines. This is different from taking the medication three times daily (three doses spread across daylight hours), once daily (a single dose in 24 hours), or every hour (which would be far too frequent for most drugs). The goal with twice-daily dosing is to balance effectiveness with safety while keeping the schedule simple for owners.
