Anticonvulsants are the drugs used to prevent seizures or convulsions. These medicines are used to reduce the occurrence of various types of Epileptic Seizures/Epilepsy. The anticonvulsants are also known as antiepileptic drugs. Although, all epileptic seizures are not convulsions, and all convulsions are not caused by epileptic seizures.
Sometimes the word fit is often used to describe the seizures and convulsions.
