Indications

Serontin is used to help control absence seizures.

⚠️ Always consult a registered physician before taking any medicine.

Pharmacology

Ethosuximide works by suppressing the paroxysmal three cycle per second spike and wave activity linked to the lapses of consciousness seen in absence (petit mal) seizures. It reduces the frequency of epileptic attacks, apparently by depressing the motor cortex and raising the threshold of the central nervous system to convulsive stimuli.

Pregnancy & Breastfeeding

Ethosuximide crosses the placenta, so the risks and benefits should be carefully weighed when treating or counseling women of childbearing potential who have epilepsy. The medicine also passes into breast milk and should only be used by nursing mothers if the benefits clearly outweigh the risks; breastfeeding is best avoided.

⚠️ Talk to your doctor before taking any medicine during pregnancy or while breastfeeding.
