Calculation specification
Reviewed on:
This calculator is not a diagnosis, treatment plan, or prescription. Please consult a qualified clinician about your medical decisions.
Formula basis
Total tablets = doses per day x tablets per dose x number of days. Full sheets = floor(total tablets / tablets per sheet). Remaining tablets = total tablets mod tablets per sheet.
Calculation method
Calculates the total number of tablets needed from the daily dosing frequency, dose per administration, and number of days, then divides that total by the selected sheet size to find the number of full sheets and the remaining tablets.
Exclusions and checks required
This is a simple arithmetic calculation (multiplication, division, and remainder) and does not judge whether a given dispensing or sheet-splitting method is appropriate.
When dispensing the remaining (leftover) tablets, cutting a PTP blister sheet into single-tablet units increases the risk of accidental swallowing of the packaging, as warned by the Ministry of Health, Labour and Welfare of Japan. For elderly patients in particular, caregiver supervision or unit-dose packaging is recommended.
Some medications have dosing limits that this simple sheet-count calculation cannot account for when determining whether dispensing is appropriate.

If the 2 leftover tablets are cut from the PTP sheet for dispensing, thoroughly instruct the patient on preventing accidental swallowing of the packaging.
