1. What is Days Supply Calculation?

Days supply calculation determines how long a medication will last based on the total quantity and the prescribed daily dosage. For topical creams, this helps ensure patients have adequate medication supply and proper refill timing.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( \text{Quantity} \) — Total amount of cream (grams or milliliters)
• \( \text{Daily Dose} \) — Amount used per day (grams or milliliters per day)

Explanation: This straightforward calculation divides the total quantity by the daily consumption rate to determine how many days the medication will last.

3. Importance of Days Supply Calculation

Details: Accurate days supply calculation is essential for medication adherence, preventing treatment interruptions, insurance billing, and proper pharmacy inventory management.

4. Using the Calculator

Tips: Enter the total quantity in grams or milliliters, and the daily dose in grams or milliliters per day. Ensure both values are positive numbers with daily dose greater than zero.
