Was the patient treated with this drug before the first dose entered above?
If earlier doses are missing, enter them (then answer No), or use Steady state mode if the patient has been on the same regimen for months.
Planned regimen after the last entered dose (optional)
Leave both empty to continue with the interval and dose found in the entered history.

How to read these results
- Band (5–95%): 90% plausible range for the true concentration. It does not include assay error, so a future measured value may fall outside it.
- P(trough > target): chance the true trough stays above your target, at your chosen dates.
- Median trough [5–95%]: the same distribution in µg/mL.
