Gabitril is only approved for use with other anti-epilepsy medicines to treat partial seizures in adults and children 12 years and older

If you are taking Gabitril, you should not stop the drug on your own; you should speak to your healthcare professional about this as soon as you can.

This information reflects FDA’s preliminary analysis of data concerning this drug. FDA is considering, but has not reached a final conclusion about, this information. FDA intends to update this sheet when additional information or analyses become available.

Who Should Not Take Gabitril?

Healthcare professionals are allowed to, and sometimes do, prescribe drugs for uses that are not in the labeling.
