Why Maren Ellis is a pen name
RefillMath is written under a pen name to keep the editor’s private life separate from the site. The pen name does not hide who is responsible for the site: the owner is identified in our Legal Notice. Everything published here is signed as Maren Ellis.
What Maren Ellis does at RefillMath
- Reads the manufacturers’ price pages and the full terms of each savings card and direct-purchase program.
- Reads Medicare.gov and CMS documents, and FDA information that affects coverage and cost.

What Maren is not
Maren Ellis is not a doctor, pharmacist, nurse, insurance agent or financial advisor. RefillMath does not give advice about treatment, doses or which medicine to take, and it does not tell you which way to pay is right for you. It shows the published numbers so you can compare them and ask better questions of your doctor, pharmacist or insurer.
What the site is based on

Why doesn’t Maren write about doses or results?

How can I check Maren’s work?

Can I ask Maren about my own cost?
You can ask how a figure on the site was worked out, and Maren will point you to the source and the formula. Your own cost depends on your plan and your pharmacy, so for that your insurer, your pharmacist or Medicare can give you a firm answer. Our calculators can help you estimate it before you ask.
Is Maren paid by a drug maker or pharmacy?
No. RefillMath does not take money from drug makers, pharmacies, insurers or telehealth companies, and it does not use affiliate links.
