Dosing & adjustment · Antibiotic dosing calculator
Antibiotic dosing calculator that surfaces the right adjustment
Antibiotic dosing carries two pressures at once: get the dose right for the patient, and get it right for stewardship. Both are easy to get wrong when renal function, weight, or indication shifts the figure away from the dose you remember.
Prescriber.io is an antibiotic dosing calculator that brings those factors together. It surfaces weight-based and indication-based antibiotic dosing, flags renal adjustments where kidney function suggests them, and points to the cited source behind each figure. The licensed clinician reviews the suggested dose, verifies it against official sources, and signs. It is dosing decision support for prescribers, not autonomous prescribing.

Why it works
What your group gets with antibiotic dosing calculator
Dosing in context
The calculator factors weight and indication into the suggested antibiotic dose, so the figure reflects the patient rather than a default.
Renal adjustments flagged
Where kidney function suggests a change, the assistant flags the renal adjustment clearly, which is a common and easily missed step for antibiotics.
Cited and reviewable
Each suggested dose points to its source so the prescriber can verify against official labeling before signing.
What it handles
Checked, flagged and suggested for your review
The decision-support card checks the prescription for interactions, flags contraindications and allergy blockers, surfaces renal and hepatic dose adjustments, and suggests guideline-based alternatives. You confirm, verify against official sources, and sign off.
- Surfaces weight and indication-based antibiotic dosing
- Flags renal dose adjustments
- Highlights interaction-driven changes
- Points to the cited source per figure
- Clinician verifies the dose and signs
Interaction flagged for review
A potential drug interaction is surfaced on the sample prescription for the clinician to review. The card flags it for your judgment and does not prescribe.
Renal dose adjustment suggested for review. Confirm against official sources before prescribing. Decision-support for review and sign-off.
Why Prescriber.io
One integrated check at the point of care
Not separate lookups stitched together. Check interactions, flag contraindications and suggest alternatives in one calm card, with the clinician signing off on every prescription.
Checks interactions and contraindications
A second set of eyes flags drug interactions, contraindications and allergy blockers for review on every prescription, so a missed interaction is less likely to slip past at the end of a long clinic.
Surfaces dosing guidance
Renal and hepatic dose adjustments surface alongside the checks, so a dose that should be adjusted for organ function is raised for you to confirm before you prescribe.
Suggests guideline-based alternatives
When a flag warrants it, the card suggests guideline-based alternatives with a one-line rationale and cited sources. The suggestion saves the lookup, never the judgment.
