Plan dose intervals (1, 2, 3, 4 or 6 times a day), learn what "3 times a day" really means, and get general missed-dose guidance.
Enter how often you take the medicine and the time of the first dose. The planner lists every dose at even intervals for up to 30 days.
Example: 2026-10-09 08:00.
1–30 days.
"Times a day" means evenly spaced doses around the clock — not "at meals". Tap a frequency to see its meaning.
General guidance only. Your medicine's label and your doctor or pharmacist always come first.
How many hours from now until the next dose is due.
"Times a day" is a shorthand for an even interval: 1× a day = every 24 hours, 2× = every 12 hours, 3× = every 8 hours, 4× = every 6 hours, 6× = every 4 hours. For example, "3 times a day" starting at 08:00 gives 08:00, 16:00 and 00:00 (midnight) — not breakfast, lunch and dinner. Even spacing keeps medicine levels steadier in your body.
This calculator plans timing only. It never computes milligram doses and is not tied to any specific medicine.
"3 times a day" means one dose every 8 hours, evenly spaced around the clock — for example 08:00, 16:00 and midnight. It does not mean simply breakfast, lunch and dinner, which would bunch the doses too close together during the day and leave a long gap overnight.
"Twice a day" means one dose every 12 hours — for example 08:00 and 20:00. Even spacing keeps the amount of medicine in your body steady between doses.
"4 times a day" means one dose every 6 hours — for example 08:00, 14:00, 20:00 and 02:00. Because the interval is short, one dose usually falls overnight; check with your pharmacist whether the schedule may be shifted, but do not change it on your own.
General guidance: if more than half the interval remains before the next dose, take the missed dose as soon as you remember. If the next dose is less than half an interval away, skip the missed one and take the next dose at its scheduled time. Never take two doses at once to make up for a missed one. Always follow the specific medicine label and your doctor or pharmacist's instructions first.
Even spacing is generally recommended so medicine levels stay steady, and bunching doses together can change how well the medicine works or increase side effects. If an every-8-hour or every-6-hour schedule is hard to follow, ask your doctor or pharmacist — some labels allow adjusted timing, but that decision belongs to them, not to this calculator.
No. This is a generic timing calculator: it plans dose intervals (every 24, 12, 8, 6 or 4 hours) and never computes milligram amounts or drug-specific limits. Schedulers for a specific medicine — such as an Aleve (naproxen) scheduler with its own label limits like maximum tablets per 24 hours — are separate tools, because those limits come from that medicine's label.
No. This tool is educational only: it computes dose timing from the frequency you enter. It does not replace your doctor, pharmacist, or the medicine label. Always follow the specific instructions for your medicine.
