1. What is DDS (Days Supply)?

DDS (Days Supply) calculates the number of days a medication will last based on the total quantity and daily dosage. It helps patients and healthcare providers manage medication schedules and refill timing.

2. How Does the Calculator Work?

The calculator uses the DDS formula:

Where:

• \( Quantity \) — Total amount of medication (units)
• \( Daily\ Dose \) — Amount taken per day (units/day)

Explanation: The formula divides the total quantity by the daily consumption rate to determine how many days the supply will last.

3. Importance of Days Supply Calculation

Details: Accurate days supply calculation is essential for medication adherence, preventing treatment gaps, managing pharmacy refills, and optimizing healthcare costs.

4. Using the Calculator

Tips: Enter the total quantity in units and the daily dose in units per day. Both values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What units should I use for quantity and daily dose?
A: Use consistent units (e.g., tablets, capsules, mL, mg) for both quantity and daily dose. The calculator works with any unit as long as they match.

Q2: How do I calculate for medications taken multiple times per day?
A: Multiply the single dose by the number of times taken daily. For example, if taking 2 tablets twice daily, daily dose = 2 × 2 = 4 tablets/day.

Q3: What if my medication has different morning and evening doses?
A: Add the morning and evening doses together to get the total daily dose before using the calculator.

Q4: Can I use this for liquid medications?
A: Yes, as long as you use consistent volume units (mL, teaspoons, etc.) for both quantity and daily dose.

Q5: How accurate is this calculation for real-world use?
A: This provides a theoretical calculation. Actual days supply may vary due to missed doses, dosage adjustments, or other clinical factors.
