There are multiple interactions reported between these two agents.

Interaction Details

Ethosuximide is classified as belonging to the following category: Cns Depressants

Theoretically, concomitant use of 1,4-butanediol with CNS depressants may potentiate respiratory and CNS depression.
1,4-Butanediol is metabolized to gamma-hydroxybutyrate (GHB). Concomitant use of CNS depressants with GHB may cause serious CNS and respiratory depression.

Interaction Rating

Major

Likelihood of Occurrence

Probable

Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports.

Interaction Details

Ethosuximide is classified as belonging to the following category: Anticonvulsants

Theoretically, concomitant use of 1,4-butanediol with certain anticonvulsants may potentiate respiratory and central nervous system (CNS) depression or increase the risk of seizures.
1,4-Butanediol is metabolized to gamma-hydroxybutyrate (GHB). Concomitant use of anticonvulsants that have sedative effects with GHB may cause serious CNS and respiratory depression. GHB might also reduce the effectiveness of anticonvulsants since it also can cause seizures.

Interaction Rating

Moderate

Likelihood of Occurrence

Possible

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists

Ethosuximide Overview

Ethosuximide is used to control absence seizures (petit mal) (a type of seizure in which there is a very short loss of awareness during which the person may stare straight ahead or blink his eyes and does not respond to others). Ethosuximide is in a class of medications called anticonvulsants. It works by reducing abnormal electrical activity in the brain.
