Terms of Service

Last updated: April 29, 2026

By using Prescription Refill Calculator you agree to the terms below. If you do not agree, please do not use the calculator or rely on the content published here. These terms apply to every page on this domain, including the calculator, blog, and any related landing pages.

Medical Disclaimer

The refill date, days remaining, and early-fill window shown by this calculator are mathematical estimates based on the inputs you provide. They are not medical advice, prescription advice, or a substitute for the judgment of your prescriber, pharmacist, or insurance plan. Always confirm your refill timing with the pharmacy that filled your prescription, especially for controlled substances, biologics, or any medication where a missed dose could be dangerous.

Accuracy

The formulas used here follow the National Association of Boards of Pharmacy (NABP) Model Pharmacy Act standards and CMS Medicare Part D dispensing rules as published. We update content when those standards change. Even so, individual insurance plans may apply stricter early-fill windows, quantity limits, or step-therapy rules that this calculator cannot know about. Treat every result as a starting point, not a guarantee.

Acceptable Use

You may use the calculator and read the blog freely for personal, non-commercial purposes. You may not scrape the site at high frequency, embed our calculator inside another commercial product, repackage our content for resale, or attempt to circumvent rate limits or analytics. Excerpts of blog posts may be quoted with attribution and a link back to the original article.

Limitation of Liability

Prescription Refill Calculator, its operators, and its contributors are not liable for any direct, indirect, incidental, or consequential damages arising from use of the calculator, the blog, or any information presented on this site. This includes (without limitation) missed refills, denied claims, adverse health outcomes, or financial losses. You are responsible for verifying any medication-related decision with a licensed pharmacist or prescriber.

Intellectual Property

The site design, written content, illustrations, and original code on Prescription Refill Calculator are owned by their respective creators and protected by copyright. Linking to articles is welcome. Wholesale republication, resale, or training of generative-AI models on this content without permission is not.

Third-Party Links

Some articles link to outside sources such as the FDA, NABP, CMS, or pharmacy chain pages. We do not control those sites and are not responsible for their content, policies, or availability. Verify any external claim against the original source before acting on it.

Changes to These Terms

We may revise these terms when product features change or when regulations are updated. Material changes will be reflected in the "Last updated" date above. Continued use of the site after a change means you accept the revised terms.

Governing Law

These terms are governed by the laws of the United States. Any dispute that cannot be resolved informally will be settled by binding arbitration in the operator's state of residence.
