Q: Abrupt withdrawal of which of the following intravenous (IV) infusion drug may cause rebound seizures and should be "weaned off" with coverage of other anti-epileptic drugs during management of status epileptics?
A) Lorazepam
B) Propofol
C) Phenobabital
D) Phenytoin
E) Levetiracetam
Answer: B
Propofol should be weaned off as abrupt withdrawal of propofol may cause rebound seizures due to its very short half life. Coverage should be established with other longer-acting anti-epileptic drug. Lorazepam and Phenobarbital have relative longer half lives and provide good umbrella when short acting propofol is taken off.
Phenytoin and Levetiracetam are not given as IV infusion.
