General Use

Calculate
Runs the selected module.
Copy
Copies the displayed result text, including the main result and supporting details.
Reset
Clears the card back to default values.
Result boxes now show the answer first.
The top line is the main result. Supporting math, assumptions, and warnings appear underneath so the answer is easier to scan during workflow interruptions.

Calculator histories keep the 5 most recent entries. Once history is full, the newest result replaces the oldest. The main Calculator uses AC instead of Reset because it behaves like a standard calculator.

Standard Day Supply

What it is for

Day-supply support for tablets/capsules, liquids, simple titration schedules, and multi-step titration schedules.

Fields / controls

Calculation type Tablets/Capsules Liquid mL Simple Titration Multi-Step Titration Qty Dispensed Used Per Day mL Dispensed mL Per Dose Doses/Day Starting Dose Change by Target Dose Adjust Every Direction Step Dose Step Duration Unit(s) Per Day Optional Quantity Coverage Estimate Rounding

How to use

  1. Choose Tablets/Capsules, Liquid mL, Simple Titration, or Multi-Step Titration.
  2. For Tablets/Capsules: enter Qty Dispensed and Used Per Day.
  3. For Liquid mL: enter mL Dispensed, mL Per Dose, and Doses/Day.
  4. For Simple Titration: enter Starting Dose, Change by, Target Dose, Adjust Every, interval unit, direction, and optional Qty Dispensed.

  7. Choose rounding, then tap Calculate.
Multi-Step Titration is for staged schedules.
Use it when the directions move through multiple dose levels or time blocks instead of one simple increase/decrease. The calculator totals the scheduled use across the entered steps, estimates coverage when quantity is provided, and assumes any remaining quantity continues at the final entered dose.

Example: Step 1 uses 1 tablet daily for 7 days, Step 2 uses 2 tablets daily for 7 days, and Step 3 uses 3 tablets daily afterward. Verify the actual prescription directions and pharmacist guidance before applying the result.
