Reference cards, not a calculator
Small static cards - not live calculators tied to your chart. Use them to prepare questions for a clinician or pharmacist.

Ivermectin weight card
Label parasites only, milligrams per kilogram framing - ivermectin brief and weight dosing note.

These cards summarize published briefs. They are not medical advice. Open the lens disclaimer.
