Before using tiagabine:

Some medical conditions may interact with tiagabine. Tell your doctor or pharmacist if you have any medical conditions, especially if any of the following apply to you:

  • if you are pregnant, planning to become pregnant, or are breast-feeding
  • if you are taking any prescription or nonprescription medicine, herbal preparation, or dietary supplement
  • if you have allergies to medicines, foods, or other substances
  • if you have a history of liver problems or status epilepticus (continuous seizure activity or a series of seizures without a full return to consciousness)
  • if you have a history of mental or mood problems (eg, depression), or suicidal thoughts or actions

Some MEDICINES MAY INTERACT with tiagabine. Tell your health care provider if you are taking any other medicines, especially any of the following:

  • Medicines that may increase your risk of seizures (eg, antidepressants, antipsychotics, stimulants, narcotic pain medicines) because the risk of seizures may be increased. Ask your doctor if you are unsure if any of your medicines may increase your risk of seizures
  • Carbamazepine, phenobarbital, phenytoin, or primidone because they may decrease tiagabine's effectiveness

This may not be a complete list of all interactions that may occur. Ask your health care provider if tiagabine may interact with other medicines that you take. Check with your health care provider before you start, stop, or change the dose of any medicine.

How to use tiagabine:

Use tiagabine as directed by your doctor. Check the label on the medicine for exact dosing instructions.

  • Tiagabine comes with an extra patient information sheet called a Medication Guide. Read it carefully. Read it again each time you get tiagabine refilled.
  • Take tiagabine by mouth with food.
  • Do not suddenly stop taking tiagabine. Suddenly stopping tiagabine may cause seizures to occur more often. If you need to stop tiagabine or add a new medicine, your doctor will gradually lower your dose.
  • If you miss a dose of tiagabine, take it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not take 2 doses at once. If you miss more than 1 dose of tiagabine, contact your doctor.

Ask your health care provider any questions you may have about how to use tiagabine.

Important safety information:

  • Do not drink alcohol or use medicines that may cause drowsiness (eg, sleep aids, muscle relaxers) while you are using tiagabine; it may add to their effects. Ask your pharmacist if you have questions about which medicines may cause drowsiness.
  • If you develop new or worsening seizures, contact your doctor right away.
  • Patients who take tiagabine may be at increased risk for suicidal thoughts or actions. The risk may be greater in patients who have had suicidal thoughts or actions in the past.
