Medication Schedule
Medication scheduling ensures doses are evenly spaced throughout the day for consistent blood levels.
Hours between doses = 24 / Doses per Day
Dose N time = First Dose Time + (N - 1) × Hours Between Doses
Common dosing schedules:
- Once daily (QD): Every 24 hours
- Twice daily (BID): Every 12 hours
- Three times daily (TID): Every 8 hours
- Four times daily (QID): Every 6 hours
Important reminders:
- Some medications must be taken with food, others on an empty stomach
- “Three times daily” often means during waking hours, not a strict 8-hour interval — check with your pharmacist
- Set phone alarms for each dose time
- Always follow your doctor’s or pharmacist’s specific instructions over general guidelines
