Compute BSA-based dosing fast for careful planning. Choose route, days, and rounding. This tool supports review, not prescribing decisions.
| Height (cm) | Weight (kg) | Dose (mg/m2) | Route | Days | Adj (%) |
|---|---|---|---|---|---|
| 170 | 70 | 100 | IV | 3 | 100 |
| 160 | 55 | 80 | IV | 5 | 100 |
| 180 | 90 | 100 | Oral | 5 | 100 |

Etoposide protocols frequently express intensity as mg/m2 per day. This calculator converts height and weight to body surface area using the Mosteller equation, then multiplies BSA by the entered intensity. In adults, typical BSA values cluster near 1.6 to 2.2 m2, so a 100 mg/m2 intensity can map to roughly 160 to 220 mg daily before adjustments.
Clinical dosing decisions may require proportional changes for toxicity, organ function, or protocol amendments. The adjustment field applies a percentage multiplier after the base BSA calculation, keeping math transparent. For example, a 75% adjustment scales a 200 mg estimate to 150 mg. Notes are stored in exports to support review during pharmacy screening or chart checks.
Intravenous schedules are commonly used in multi-agent regimens, while oral dosing may be chosen for outpatient convenience. Because oral exposure can be variable, some regimens use an approximate conversion. The optional oral setting applies a 2x multiplier to the intensity entry before BSA. This is a simplification and must be reconciled with the specific protocol, formulation, and institutional policy.
Rounding supports operational practice, such as aligning with vial sizes, compounding limits, or dosing bands. The rounding step applies to the calculated daily amount and the course total. Small steps like 1 mg preserve precision, while 5 to 10 mg steps improve dispensing simplicity. Rounding should follow local standards and minimize clinically meaningful deviation.
Many etoposide schedules run for 3 or 5 consecutive days per cycle, with cycle lengths often 21 to 28 days. The tool reports both an estimated daily dose and a course total, enabling quick reconciliation with order sets and cumulative exposure targets. The visualization shows daily repetition across the selected days and compares daily versus total values. Tracking course totals also helps compare cycles, especially when dose holds or delays occur clinically.
This calculator is designed for education, double-checking, and documentation support. It does not evaluate contraindications, drug interactions, laboratory thresholds, infusion rates, or protocol-specific caps. Use it alongside validated references and institutional guidance, and confirm every output with qualified oncology clinicians and pharmacy verification before prescribing or dispensing.
It uses the Mosteller method: BSA equals the square root of height in cm times weight in kg, divided by 3600.
No. You must enter the regimen-specific intensity. The output only reflects your inputs, plus the chosen adjustment and rounding settings.
Some practices apply an approximate conversion due to variable oral exposure. This option multiplies your intensity entry by two before BSA. Confirm with your protocol and pharmacy policy.
It applies a proportional modifier after the base BSA calculation, such as 75% or 125%. Use it only when a clinician specifies a modification.
Select a step aligned with local preparation and dispensing practice. Smaller steps preserve precision, while larger steps can simplify compounding and documentation.
They export the latest saved calculation row, including inputs, BSA, daily estimate, course total, timestamp, and your notes for documentation.
