90 Day Prescription Refill Calculator

90-Day Prescription Refill Calculator: Never Run Out of Medication Again

Managing prescription medications can be challenging, especially when dealing with chronic conditions that require long-term treatment. Missing a refill can lead to gaps in medication, which may worsen health outcomes. To simplify this process, we’ve developed a 90-Day Prescription Refill Calculator that helps you determine exactly when to request your next refill.

In this article, we’ll explain:

• Key terms used in the calculator

• Why these calculations matter

• How to interpret the results

• How the calculator works

Key Terms & Their Importance

1. Current Supply

This refers to the amount of medication you currently have on hand. It can be measured in:

• Pills/Tablets (e.g., 30 pills left)

• Milliliters (ml) (for liquid medications)

• Milligrams (mg) or Grams (g) (for medications measured by weight)

• Units/Doses (for insulin, inhalers, etc.)

Why it matters: Knowing your current supply helps determine how long your medication will last before you need a refill.

2. Daily Usage

This is the amount of medication you take per day. For example:

• 1 pill per day

• 5 ml of liquid medication twice daily

• 2 doses of an inhaler daily

Why it matters: If you take more or less than prescribed, your refill timeline changes. Accurate daily usage ensures precise calculations.

3. Start Date

The date you began using your current supply.

Why it matters: The calculator uses this date to project when you’ll run out and when to refill.

4. Refill Duration (Default: 90 Days)

This is how long your next prescription should last (typically 30, 60, or 90 days).

Why it matters: Insurance plans often cover 90-day supplies for maintenance medications, reducing pharmacy trips.

5. Gender (Optional)

While not critical for all medications, some dosages vary by gender (e.g., certain heart medications).

Why it matters: Some medications have gender-specific dosing guidelines, though this is rare.

Understanding the Calculator’s Results

After entering your details, the calculator provides:

1. Current Supply Will Last (Days Left)

• Shows how many days your medication will last based on your daily usage.

• Example: "30 pills at 1 pill/day = 30 days left."

2. Projected Run-Out Date

• The exact date you’ll run out if you don’t refill.

• Example: "If you started on Jan 1, you’ll run out by Jan 30."

3. Recommended Refill Date

• Suggests when to request a refill (typically 7 days before running out).

• Adjusts for weekends/holidays if selected.

• Example: "Refill by Jan 23 to avoid gaps."

4. 90-Day Supply Quantity Needed

• Calculates how much medication you’ll need for the next 90 days.

• Example: "1 pill/day × 90 days = 90 pills needed."

5. Interpretation & Warnings

• If your supply is low (<14 days), you’ll get an urgent warning.

• If supply is moderate (14-30 days), you’ll get a reminder to refill soon.

How the Calculator Works

1. Enter Your Medication Details

   • Name, current supply, daily usage, and start date.

2. Select Units (pills, ml, mg, etc.) for consistency.
