Formula Used in the Calculator
The logic behind the calculator is simple and based on basic arithmetic.
1. Medication Used
Used Medication = Daily Dosage × Number of Days
This tells how many pills are consumed during the selected period.
2. Remaining Pills
Remaining Pills = Total Quantity Prescribed − Used Medication
This shows how many pills are still available.
3. Refill Decision
If remaining pills are:
- Less than or equal to 0 → Refill Needed: Yes
- More than 0 → Refill Needed: No
Example Calculation
Let’s understand with a real-life example:
- Total Quantity Prescribed = 90 pills
- Daily Dosage = 2 pills per day
- Days Supplied = 30 days
Step 1: Calculate Used Pills
2 × 30 = 60 pills used
Step 2: Calculate Remaining Pills
90 − 60 = 30 pills remaining
Step 3: Refill Status
Since pills are remaining, refill is NOT needed.
Results Explained
When you use the calculator, you will see three main results:
1. Total Days Supply
Shows the number of days covered by your medication usage.
2. Remaining Pills
Displays how many pills are still left after usage.
3. Refill Needed
Indicates whether you should request a refill soon.
Medication Tracking Table Example
Below is a simple example of how medication usage is tracked over time:
| Day Range | Daily Dosage | Total Used Pills | Remaining Pills | Refill Status |
