These sample rows demonstrate how the input fields can be used for planning. Verify real prescriptions separately.
| Scenario | Target Dose (mg) | Strength (mg) | Tablets Available | Interval (hours) | Days | Split | Rounding |
|---|---|---|---|---|---|---|---|
| Example A | 500 | 250 | 30 | 8 | 7 | 0.5 | Nearest |
| Example B | 650 | 325 | 24 | 12 | 10 | 0.5 | Nearest |
| Example C | 375 | 125 | 60 | 6 | 5 | 0.25 | Ceil |
Exact tablets per dose = Prescribed dose ÷ Tablet strength
Rounded tablets per dose = Exact tablets rounded to the selected split increment
Actual dose per dose = Rounded tablets per dose × Tablet strength
Doses per day = 24 ÷ Dosing interval in hours
Planned daily dose = Actual dose per dose × Doses per day
Course tablets needed = Rounded tablets per dose × Doses per day × Treatment days
Days of supply = Tablets available ÷ Tablets used per day
Projected intake after next dose = Already taken today + Actual dose per dose
Dose variance % = ((Actual dose per dose − Prescribed dose) ÷ Prescribed dose) × 100
It estimates tablets per dose, actual milligrams delivered, doses per day, planned daily total, days of supply, course need, and warning checks.
Many scored tablets can be split. The split increment setting lets you round to whole, half, or quarter tablets. Always confirm that splitting is safe for the medication.
Tablets come in fixed strengths. When the target dose does not divide evenly, the calculator rounds to your allowed split size, which changes the delivered dose slightly.
It compares the planned daily intake, and the projected intake after the next dose, against the maximum daily limit you entered. It is only as accurate as your inputs.
No. It is an educational planning tool. Prescriptions, patient factors, interactions, kidney or liver status, and product-specific instructions must still be reviewed professionally.
Rounding changes tablets used per dose. Even a small difference becomes larger across several daily doses, so the available bottle may last more or fewer days.
The calculator uses an average doses-per-day value of 24 divided by the interval. That works for planning, but real schedules may need clinician-approved timing adjustments.
Use extra caution. Pediatric dosing, pregnancy, organ impairment, modified-release tablets, and medicines with narrow safety margins should be checked directly by a clinician or pharmacist.
