How to take Ethosuximide?
Ethosuximide comes as a capsule and as a syrup (liquid) to be taken by mouth. It's generally taken one or more times a day. Take ethosuximide at around the same time each day. It works by regulating the abnormal electrical activity in the brain that occurs during seizures. The recommended dosage for patients 3 to 6 years of age is one capsule (250 mg) per day; for patients 6 years of age and older, two capsules (500 mg) per day. The dose should then be individualized according to the patient's response. The dose should be increased by small increments. One useful method is to increase the daily dose by 250 mg every four to seven days until a minimum control is achieved with minimum side effects. Dosages exceeding 1.5 g daily in divided doses should only be administered under the strictest supervision of the physician. The optimum dose for most pediatric patients is 20 mg/kg/day.

- Stomach cramp
The exact mechanism of action is not fully understood, but the most likely effect of ethosuximide is the partial antagonism of the T-type calcium channels of the thalamic neurons. This leads to a decrease in thalamocortical neurons bursting, which stabilizes nerve activity in the brain and prevents seizures.
Ethosuximide generates barbiturate-like toxicity, characterized by the nervous system and pulmonary edema, nausea and vomiting when the blood level is more than 120 mcg/mL.
It may take a couple of weeks for ethosuximide to work properly, so that your child may still have seizures during this time. That's because the amount of medicine needs to be increased slowly.
Most children with lack of epilepsy eventually overcame the condition without complications. A child can have a normal life at school and at home with proper treatment.
It is dispersed through total body water and metabolized in the liver. The half-life of ethosuximide is between 30 and 40 hours in children and between 50 and 60 hours in adults. Because ethosuximide is metabolized in the liver, people with liver disease should be treated with caution.
Ethosuximide lowers the threshold of calcium currents (T currents) in thalamic neurons. These currents, in turn, affect the oscillatory activity of the thalamocortical neurons, which are the generators of the 3-Hz spike-and-wave rhythms of patients with no epilepsy.
This medicine may increase the chance of major mal seizures in some patients. Ethosuximide may cause some people to be agitated, irritable, or have other abnormal behaviours.
