What GABITRIL is used for
This medicine is used with other medicines to control some types of seizures (fits)
in people with epilepsy. Epilepsy is a condition where you have repeated seizures.
There are many different types of seizures, ranging from mild to severe.
This medicine belongs to a group of medicines called antiepileptics or anticonvulsants.
It works by increasing the level of a chemical in the brain (gamma-aminobutyric acid,
or GABA). This controls the signals in nerve cells so that seizures do not happen.
