Ethosuximide is used in the treatment of epilepsy and seizures.
How Ethosuximide works Ethosuximide belongs to a class of medications known as anticonvulsants. It functions by binding to T-type voltage-sensitive calcium channels, regulating the influx of calcium ions in the nerves and brain. This action decreases hyperactivity in the brain and nerves, thereby helping to treat seizures.
Common side effects of Ethosuximide include nausea, vomiting, fatigue, indigestion, stomach pain, dizziness, lightheadedness, diarrhea, weight loss, headache, loss of appetite, and hiccups.
