Contact
PharmCalc is an independent project built and maintained from Texas, United States. There is no company behind it and no support desk — messages come to one inbox and are answered personally.
What to get in touch about
- A calculation looks wrong. This is the most useful message you can send. Please include the calculator name, the values you entered, the result you got, and the result you expected — the copy worked solution button gives all of that as plain text in one click.
- A reference is out of date or a guideline has been superseded. Please include the citation.
- A calculator is missing. Tell me what it is and where you would use it.
- Something is unusable with a screen reader, on a phone, or at high zoom. Accessibility problems are treated as defects, not feature requests.
- Privacy questions or a request about your data — see the privacy policy.
- Teaching use. If you want to use PharmCalc with a class or on a course, you are welcome to; do say hello.
What this inbox cannot do
Please do not send patient details or ask for advice on a specific patient. PharmCalc is an educational reference and this inbox is not a clinical service — no one here can advise on the care of an individual. Speak to a pharmacist, prescriber, or your local poisons information service.
In an emergency, contact your local emergency services.
Pharmacist review
Every formula is cited and the arithmetic is covered by an automated test suite. If you are a licensed pharmacist and would be willing to review a category, that offer would be genuinely valuable — please get in touch.
