RefillDay

Editorial Policy & Sources

Medication information affects people's health, so we hold our content to a simple standard: it should be accurate, clearly explained, honest about what we don't know, and never written to push you toward a product. This page explains how we work.

What we publish

RefillDay publishes calculators and plain-language guides about prescription days supply, refill dates, refill timing rules in the United States, and practical medication planning. We do not publish dosing advice, treatment recommendations or reviews of specific drugs.

How content is created

  • Researched from primary sources first. Federal regulations, government agencies and pharmacy industry standards come before secondary articles. Key sources are listed below.
  • Written for patients and caregivers. We explain terms such as "days supply" and "refill too soon" in everyday language and use worked examples you can check.
  • Careful about uncertainty. Where rules differ by insurance plan, pharmacy benefit manager, state or medication, we say so instead of presenting one rule as universal.
  • Math you can verify. Every formula, rounding rule and date convention is published on How we calculate, and the calculators are tested against those examples.

Review and updates

Content is reviewed periodically and whenever we learn of a relevant change. Each calculator page shows the date it was last reviewed (currently October 6, 2026). We don't claim medical or pharmacy credentials we don't have; RefillDay is an informational tool, and your pharmacist or prescriber remains the authority on your care.

Corrections

If you spot an error, please tell us through the contact page and choose "A correction to the content." We review every correction request, fix confirmed errors promptly, and update the review date on the affected page.

Advertising and independence

  • Advertisers have no input into our calculators or articles.
  • We don't publish sponsored content or paid placements in our guides.
  • Ads are clearly labeled "Advertisement" and kept apart from the calculator.
  • We don't recommend or rank specific pharmacies, insurance plans or medications.

Privacy by design

The calculators run in your browser, and the medication details you enter are not sent to our server. This is a deliberate editorial choice: a tool about your medications shouldn't need to collect them. See the privacy policy.
