Fast BSA, dosing, and vial planning for clinicians. Enter labs and reductions to reflect protocols. Export results to CSV or PDF for documentation today.
Important: This calculator is for education and documentation support. Always follow your institution’s protocol and a licensed clinician’s judgment.
Illustrative examples only. Do not use these values for clinical decisions.
| Example | Height (cm) | Weight (kg) | BSA (Mosteller) | Dose (mg/m²) | Reduction (%) | Rounded dose (mg) |
|---|---|---|---|---|---|---|
| A | 165 | 60 | 1.658 | 1000 | 0 | 1,660 |
| B | 178 | 82 | 2.014 | 900 | 25 | 1,350 |
| C | 155 | 48 | 1.438 | 1250 | 10 | 1,625 |
Choose the method that matches your local standard.
Enter protocol-derived values; the tool does not choose a regimen.
Gemcitabine orders are commonly expressed as mg per square meter (mg/m²). This calculator accepts height (cm) and weight (kg) to estimate body surface area (m²), then multiplies by the ordered mg/m² to produce a planned milligram dose. Optional fields support a percentage reduction, a maximum cap in mg, and rounding to a defined increment for preparation practice. You may also enter a validated manual BSA if measured elsewhere. Document the weight basis used because policies differ.
Two BSA equations are provided: Mosteller and DuBois. Mosteller is simple and widely used for routine dosing; DuBois can yield slightly different values, especially at weight or height extremes. Record the selected method because changing equations can change the final dose. The tool displays BSA to three decimals to keep downstream calculations consistent. In borderline cases, small BSA changes can shift the milligram result.
Outputs are separated into planned dose, reduced dose, capped dose, and rounded dose. This structure helps you audit each adjustment step against an order set. The calculator does not choose a regimen or schedule; it only performs arithmetic using the values you enter. Always cross-check units, patient identifiers, and the intended day of therapy. If you track delivered dose intensity, export the CSV and compare planned versus administered doses across visits.
When vial strengths are entered, the tool estimates the number of vials required and the approximate waste in milligrams after rounding. This supports documentation for compounding, inventory planning, and cost awareness. Waste estimates assume whole-vial use and do not account for shared vials, stability limits, or closed-system transfer device dead space. Include vial strength and concentration on worksheets to support pharmacy verification and reduce common transcription errors during sterile compounding.
Before preparation, confirm the protocol dose, cycle timing, and required laboratory thresholds (such as neutrophils and platelets) using your institution’s guidance. Review organ function and concurrent medications that may influence treatment decisions. Re-check calculations after significant weight change, dose holds, or schedule deviations. A second-person check of calculations and order parameters is a standard safety step in chemotherapy workflows.
It converts an ordered mg/m² dose into milligrams using body surface area, then applies optional reduction, cap, and rounding rules. It can also estimate vial counts and waste when vial strengths are provided.
Use the method required by your institution or protocol. Mosteller is commonly used because it is simple. DuBois may be used in some settings. Changing methods can change the final milligram dose.
No. You must enter the regimen-specific mg/m² from an approved protocol and confirm the correct day, cycle, and infusion plan separately.
Enter the percentage reduction specified by the prescriber or protocol for the current visit. The tool multiplies the planned dose by (1 − reduction/100). Document the clinical rationale in your record.
Use them as a planning estimate only. Real waste depends on compounding workflow, vial sharing policies, stability limits, and device dead space. Follow your pharmacy’s documentation standards for charge capture.
No. Calculations run in the browser and the page does not save data to a database. Still avoid entering identifiers unless your privacy policy permits.
