About RxToDose

Clinical decision-support tools built by a pharmacist, for clinicians.

Who We Are

RxToDose was built by a clinical pharmacist practicing in a large inpatient hospital setting, with a focus on pharmacokinetics and individualized medication dosing. The platform was developed out of a practical need: existing tools were either too slow, too opaque in their methodology, or poorly suited to real bedside workflows. What began as an internal resource has grown into a free, publicly available suite of clinical calculators used by pharmacists, physicians, and advanced practice providers.

Our Mission

To provide clinicians with fast, methodologically transparent, and privacy-respecting decision-support tools — at no cost. Every calculator on RxToDose is built around published clinical guidelines and evidence-based dosing frameworks, with clear references so practitioners can verify the underlying methodology themselves.

Design Philosophy

RxToDose is built with a workflow-first mentality. Tools are designed to minimize the number of inputs required, surface the most actionable outputs immediately, and work reliably on both desktop and mobile devices in a clinical environment. No accounts, no data collection, no paywalls. Calculations are performed locally in the browser; patient data is never transmitted to any server.

What We Cover

The platform currently includes tools for vancomycin AUC-based pharmacokinetic dosing, opioid equianalgesic conversion, parenteral nutrition macronutrient calculations, statin dose equivalency, clinical weight and body surface area estimation, MELD and MELD-Na scoring, CHA₂DS₂-VASc stroke risk stratification, and fibrinolytic (tPA/TNK) clinical reference guidelines. Additional tools are added as clinical need warrants.

Transparency & Limitations

RxToDose is intended as a clinical decision-support aid, not a replacement for professional judgment. All outputs should be interpreted in the context of the individual patient by a qualified healthcare provider.
