How to Use This Calculator
- Enter Actual Body Weight, Height, and Age.
- Set Serum Creatinine and Female Patient.
- Review Recommended Dose (mg), Dosing Interval (hours), and Estimated Trough (mcg/mL).
- Use Creatinine Clearance (CrCl) (mL/min) and Dosing Weight Used (kg) to inform your decision.
How the result changes with Actual Body Weight
| Actual Body Weight | Recommended Dose | Dosing Interval | Estimated Trough |
|---|---|---|---|
| 48 | 750 mg | 12 hours | 10.9 mcg/mL |
| 118 | 1,250 mg | 8 hours | 6.7 mcg/mL |
| 202 | 1,750 mg | 8 hours | 3.1 mcg/mL |
| 272 | 2,250 mg | 8 hours | 1.7 mcg/mL |
What each input means
- Actual Body Weight
- Patient's actual body weight in kilograms.
- Height
- Patient's height in centimeters (used for ideal body weight).
- Age
- Patient's age in years.
- Serum Creatinine
- Most recent serum creatinine level in mg/dL.
- Female Patient
- 0 = No (Male), 1 = Yes (Female). Adjusts CrCl calculation.
