Ethosuximide is a generic prescription drug that controls seizures in patients with petit mal or absence epilepsy, a nervous system disorder that causes brief seizures of less than 15 seconds. Absence seizures sometimes are barely noticeable.
Ethosuximide belongs to a class of drugs called anticonvulsants. Epileptic seizures are caused by the repetitive, overexcited, and abnormal firing of nerve cells in the brain, usually triggered by a situation or other stimulus. Ethosuximide prevents the repetitive firing of nerves by reducing the brain's excitability.
Ethosuximide is taken as a tablet or oral solution once or twice daily. Ethosuximide is usually prescribed to children.
What are the side effects of Ethosuximide?
The most common side effects of Ethosuximide include, but are not limited to, headache, dizziness, upset stomach, nausea, stomach pain, diarrhea, weight loss, loss of balance, loss of coordination, and feeling tired.
Allergic reactions are extremely rare but include hives, rashes, itching, and trouble breathing. Severe allergic reactions are possible, including Stevens-Johnson syndrome, a drug reaction that causes dark rashes, blistering, and peeling throughout the body as well as fever, sore throat, and flu-like symptoms.
