Levetiracetam for Seizure
Pediatric weight-based dosing has a median of 30 mg/kg across 14 published protocols, with the middle half between 20 and 60.
Doses far off from what other protocols give are likely misreads, so they are left out until checked. How that works.
Pediatric, weight-basedmg/kg
| min | p25 | median | p75 | max |
|---|---|---|---|---|
| 15 | 20 | 30 | 60 | 60 |
Values in mg/kg. One value per source (that source's median), so a document listing a medication five times still gets one vote.
