What is tiagabine?
Tiagabine is an anti-epileptic medication, also called an anticonvulsant.
Tiagabine is used in combination with other medications to treat partial seizures in adults and children who are at least 12 years old.
Tiagabine may also be used for purposes not listed in this medication guide.
Call your doctor at once if you have new or worsening seizures.
Do not stop using tiagabine suddenly. Stopping suddenly may cause increased seizures.
Before taking this medicine
You should not use tiagabine if you are allergic to it.
Tell your doctor about all other seizure medications you currently use. The safest dose of tiagabine may depend what other medicines you take in combination with it.
New seizures have occurred in some people who are not epileptic who take medicine for partial seizures.
To make sure tiagabine is safe for you, tell your doctor if you have:
a confirmed diagnosis of epilepsy;
a history of a seizure that did not stop (also called status epilepticus);
a history of abnormal brain wave test (EEG); or
Some people have thoughts about suicide while taking seizure medication. Your doctor should check your progress at regular visits. Your family or other caregivers should also be alert to changes in your mood or symptoms.
Follow your doctor's instructions about taking seizure medication if you are pregnant. Do not start or stop taking this medicine without your doctor's advice, and tell your doctor right away if you become pregnant. Tiagabine may cause harm to an unborn baby, but having a seizure during pregnancy could harm both mother and baby. The benefit of preventing seizures may outweigh any risks to the baby.
If you are pregnant, your name may be listed on a pregnancy registry. This is to track the outcome of the pregnancy and to evaluate any effects of tiagabine on the baby.
Tiagabine can pass into breast milk and may harm a nursing baby. Tell your doctor if you are breast-feeding a baby.
Tiagabine should not be given to a child younger than 12 years old.
