Tiagabine is used with other medications to treat certain epileptic seizure disorders (e.g., partial seizures) which have not been controlled by other medications. Seizures occur because of problems with communication between nerves. Tiagabine is believed to affect certain natural substances (neurotransmitters) in the brain that slow down this communication. Regular use of tiagabine together with your other anti-epileptic medication should reduce the number of seizures you have. When tiagabine has been used for conditions other than epilepsy, serious reactions (including seizures in people who have never had them) have occurred. Therefore, the manufacturer recommends this drug only for the treatment of epilepsy.
If you miss a dose, take it as soon as you remember. If it is near the time of the next dose, skip the missed dose and resume your usual dosing schedule. Do not double the dose to catch up. If you miss taking this medication for several days, contact your doctor for instructions.
How To Use
Read the Medication Guide provided by your pharmacist before you start taking this medication and each time you get a refill. If you have any questions, ask your doctor or pharmacist. Take this medication by mouth with food, usually 2 to 4 times daily or as directed by your doctor. When you start this medication, your dosage will be increased slowly by your doctor to reduce side effects. Therefore, only one dose a day is usually taken during the first week. Follow your doctor's instructions exactly. Tiagabine is not usually used by itself. Do not stop your other anti-seizure medication unless your doctor tells you to do so. Dosage is based on your medical condition, response to therapy, and use of certain other seizure medications (see Drug Interactions section). Use this medication regularly in order to get the most benefit from it. To help you remember, take it at the same times each day. Do not stop taking this medication without consulting your doctor. Some conditions may become worse when the drug is abruptly stopped. Your dose may need to be gradually decreased. If you stop taking this medication for several days, you may need to increase your dose slowly back to your previous dosage. Talk with your doctor about how to restart the medication. Inform your doctor if your condition persists or worsens after you have reached your full dose.
Your healthcare professionals (e.g., doctor or pharmacist) may already be aware of any possible drug interactions and may be monitoring you for it. Do not start, stop or change the dosage of any medicine before checking with them first. Before using this medication, tell your doctor or pharmacist of all prescription and nonprescription/herbal products you may use, especially: a certain drug for stopping smoking (bupropion), certain anti-seizure drugs (e.g., phenytoin, carbamazepine, phenobarbital, primidone), certain recreational/street drugs such as methamphetamine ("speed") or MDMA ("ecstasy"). Certain medications increase your chances of having a seizure and may make it appear that tiagabine and your other anti-seizure medications are not working. Tell your doctor or pharmacist if you are taking other drugs which might increase seizure risk when combined with tiagabine such as bupropion, isoniazid, antipsychotic medications (e.g., phenothiazines such as chlorpromazine), stimulants (e.g., methylphenidate, dextroamphetamines) or alcohol. Tell your doctor or pharmacist if you also take drugs that cause drowsiness such as certain antihistamines (e.g., diphenhydramine), anti-anxiety drugs (e.g., diazepam), anti-seizure drugs (e.g., gabapentin, valproic acid), medicine for sleep (e.g., zolpidem, temazepam), narcotic pain relievers (e.g., codeine, fentanyl), tranquilizers, or certain antidepressants (e.g., tricyclics such as imipramine or amitriptyline). Check the labels on all your medicines (e.g., cough-and-cold products) because they may contain drowsiness-causing ingredients. Ask your pharmacist about the safe use of those products. This document does not contain all possible interactions. Therefore, before using this product, tell your doctor or pharmacist of all the products you use. Keep a list of all your medications with you, and share the list with your doctor and pharmacist.
