Ketamine for Agitation
Adult weight-based dosing has a median of 3 mg/kg across 62 published protocols, with the middle half between 2 and 4.
1,335 rows are under review across the census and excluded from every number on this page. How that works.
Adult, weight-basedmg/kg
| min | p25 | median | p75 | max |
|---|---|---|---|---|
| 1 | 2 | 3 | 4 | 5 |
Values in mg/kg. One value per source (that source's median), so a document listing a drug five times still gets one vote.
