Educational Pearls:
Lorazepam (Ativan) is dosed at 0.1 mg/kg up to a maximum of 4 mg in status epilepticus
Some ED protocols only give 2 mg initially
The maximum recommended dose of levetiracetam (Keppra) is 60 mg/kg or 4.5 g
In one retrospective study, only 50% of patients received the correct dose of lorazepam
For levetiracetam, it was only 35% of patients
Underdosing leads to complications
Higher rates of intubations
More likely to progress to refractory status epilepticus

Educational Pearls:
Opioid overdoses that are reversed with naloxone (Narcan), a mu-opioid antagonist, can precipitate acute withdrawal in some patients
Treatment of opioid use disorder with buprenorphine can also precipitate withdrawal
Opioid withdrawal...
