Count tablets across prescribed stages
Enter consecutive stages with a fixed daily frequency. Copy the tablet count, frequency and duration from complete, clarified directions. This tool counts tablets; it does not decide how a medicine should be tapered.
Quantity from the entered stages
tablets
The consecutive stages contain days in total. This is the sum of the entered durations, not a payer-verified days supply.
No quantity rounding is applied. Review every stage against the directions and confirm the quantity to dispense through your pharmacy’s normal review.

Values stay in this page and are cleared when you reload. Enter numeric values only, without patient or prescription identifiers. Edits clear the previous result so it cannot be copied as a current calculation.
A worked tablet-count example
These fictional stages demonstrate counting only. They are not instructions for a named medicine or patient.
12 + 9 + 6 + 3 = 30 tablets across 12 consecutive entered days. Applying the starting daily count to all 12 days would give 48 tablets and would ignore the later stages.
The CMS oral-products job aid, December 2015, page 1 describes calculating quantity from daily use and treatment duration. The IHS Outpatient Pharmacy manual, September 2004, Appendix B, pages 141–142 demonstrates counting complete sequential stages separately. Those historical documents support the arithmetic context; they do not establish current payer rules or a clinically appropriate taper.
Which schedules fit this calculator?
Use one row for each consecutive stage that has the same tablet count per dose and a fixed number of doses every day. All stages must use the same tablet product and strength. Enter one to twelve complete stages. Tablet counts allow up to three decimal places; each input allows up to six digits before the decimal. These are tool limits, not clinical limits.
Do not force alternate-day dosing, drug-free gaps, overlapping instructions, varying doses within one day, as-needed directions or a missing duration into this model. Use the complete schedule and your pharmacy’s reviewed calculation method. The days supply guide discusses elapsed time for packs, kits and intermittent schedules.
If directions use milligrams, confirm the corresponding tablet count and exact product before entering it. This calculator does not convert a milligram dose to tablets or determine a taper from a starting dose.
Fractional tablet counts need a product check
A mathematical fraction does not establish that a tablet can be split. FDA’s tablet-scoring guidance, March 2013, pages 2–3 discusses product-specific evaluation, labeling and splitting risks. Confirm the exact product’s labeling and the clarified directions with the pharmacist before using fractional tablet inputs. The result does not round a fractional total to a whole tablet or package.
Quantity and days supply answer different questions
This ledger counts tablets for the stages you enter. The days supply calculator estimates time from verified quantity and daily-use inputs. The sum of stage durations here does not resolve payer limits, rounding, partial fills or claim acceptance. Current payer instructions and the complete prescription govern those decisions.
