How It Works

We think Gabitril® works by helping one of the brain chemicals (GABA) to work better. It is well absorbed when taken by mouth and is best taken with food to avoid sharp rises in blood levels. It is broken down primarily by the liver. The half life is 7 to 9 hours in adults.

Forms of the Medicine

Gabitril® tablets are available in four dosage strengths; 2, 4, 12 and 16 milligrams


Gabitril® is given by mouth. It is given twice or four times per day with food. Dosing amounts and frequency of dosing will be decided by the treating physician. Dosing will usually start with about 4 milligrams per day and will likely be increased over time.

Side Effects

The most common side effects include sedation, fatigue or muscle weakness, nervousness, headache, fatigue, irritability, difficulty with concentration, tremor, and dizziness.

Information for Pregnant Women and Nursing Mothers

Safety in pregnancy has not been established. It is known that women taking antiepileptic drugs have a higher incidence of birth defects than women who are not. Women who are taking this medication and who wish to become pregnant should discuss treatment options with their physicians before the pregnancy begins. Gabitril® is passed into breast milk.

Drug Interactions

Dilantin®, Tegretol®, Mysoline® and Phenobarbital® can decrease Gabitril® levels.

Care During Treatment with Gabitril®

You should take the medicine as prescribed by your physician. If you are late in taking a dose by 2-3 hours, you should take it. If you miss a dose altogether, you should wait until the next dose and take the prescribed amount, or consult your physician. Report any unusual rashes or other side effects. As a rule, antiepilepsy drugs should not be abruptly discontinued because of the possibility of increasing seizure frequency.
