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.
Ask your doctor if you have any questions about why this medicine has been prescribed for you.
Your doctor may have prescribed it for another reason.
This medicine is not addictive.
It is available only with a doctor’s prescription.
There is not enough information to recommend the use of this medicine for children under the age of 12 years.
