The next fomepizole dose and its time, as the label states them.
Open the calculator → Runs in your browser. Data leaves only if you deliberately send a problem report from the interactive tool.
Example
- Weight
- 70 kg
- Doses given so far, counting the loading dose
- 2
- Hemodialysis
- Hemodialysis has just ended
- Time of the last dose
- 2026-10-12T08:00
- Time hemodialysis started or ended
- 2026-10-12T10:00
Result: Hemodialysis ended 2 h after the last dose, 1 to 3 hours: the label says to give half of the next scheduled dose, 350 mg (half of 700 mg), at the end (2026-10-12 10:00).
The tool opens with these values already filled in. Replace them with your own.
