Tiagabina (as hydrochloride monohydrate)

Gabitril is an antiepileptic medication. Tiagabina, the active ingredient of Gabitril, increases brain levels of gamma aminobutyric acid (GABA), thereby preventing or reducing the number of seizures (epileptic episodes).

Gabitril is used to help control epilepsy in adults and adolescents over 12 years old with partial seizures.

It is administered in combination with other medications when these alone are not sufficiently effective.

Do not take Gabitril:

• If you are allergic (hypersensitive) to tiagabina or to any of the other components of this medication included in section 6.
• If you have a severe liver disease.
• In combination with herbal preparations containing St. John's Wort (Hypericum perforatum).See “Use of other medications”.

Be especially careful with Gabitril:

• If you are under 12 years old.
• If you have generalized epilepsy, as you may experience a worsening of absences (short periods of clouded consciousness).
• If you interrupt treatment with Gabitril as it may cause a recurrence of seizures. Do not stop taking Gabitril without consulting your doctor.
• If you have anxiety or depression, or have had them in the past, these symptoms may worsen or reappear during treatment with Gabitril. Inform your doctor if you feel absent, anxious, or depressed.
• A small number of people treated with antiepileptic drugs like tiagabina have had thoughts of self-harm or suicide. If you ever experience these thoughts, contact your doctor immediately.
• If you notice an increase in the number of seizures or new types of seizures, inform your doctor. He will indicate if it is necessary to modify your treatment.
• If you observe the appearance of a skin rash, including pustules with fluid and blisters or if you observe the spontaneous appearance of petechiae on the skin or darkening of the same, contact your doctor immediately.
• If you notice any type of vision problem, contact your doctor as Gabitril may occasionally cause visual field defects.
• If your doctor has informed you that you have intolerance to some sugars, do not take Gabitril, as it contains lactose.
• If you have mild or moderate liver problems, your doctor should adjust the indicated dose of Gabitril.

If you experience (or have experienced) any of these symptoms, please inform your doctor.

Use of other medications:

If you are using, have used recently, or may need to use any of the following medications, please consult your doctor or pharmacist before starting to take Gabitril:

• Other antiepileptic medications such as phenytoin, carbamazepine, phenobarbital, and primidone, as they may reduce and shorten the effects of Gabitril.
• Rifampicin (medication for the treatment of tuberculosis), as it may reduce and shorten the effects of Gabitril.
• Herbal preparations containing St. John's Wort (Hypericum perforatum), as they should not be taken with Gabitril (see “Do not take Gabitril”).

In case you need to combine it with one or several of these medications, your doctor may need to adjust the dose of Gabitril.
