Table I. Drug coadministration with electroconvulsive therapy.

Drug	Concomitant administration with ECT
Lithium13	Discontinue before ECT. Lithium decreases the intracellular production of
	acetylcholine, may prolong the action of succinylcholine, and may prolong
	seizure duration
Tricyclic antidepressant, monoamine oxidase inhibitors	Safe
selective serotonin reuptake inhibitors14,15
Bupropion16	Controversial. Bupropion may cause prolonged seizure
Benzodiazepines	Safe, but have an anticonvulsive activity, and might raise the seizure threshold
Antipsychotics17	Safe
Clozapine18	Controversial, might induce late seizures
