Topiramate is used alone or with other medications to prevent and control seizures (epilepsy). This medication is also used to prevent migraine headaches and decrease how often you get them. Topiramate will not treat a migraine headache once it occurs. If you get a migraine headache, treat it as directed by your doctor (such as by taking pain medication, lying down in a dark room). Topiramate is known as an anticonvulsant or antiepileptic drug.
Tiredness, drowsiness, dizziness, loss of coordination, tingling of the hands/feet, loss of appetite, bad taste in your mouth, diarrhea, and weight loss may occur. Mental problems such as confusion, slowed thinking, trouble concentrating or paying attention, nervousness, memory problems, or speech/language problems may also occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly. Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects. Tell your doctor right away if any of these unlikely but serious side effects occur: signs of kidney stones (such as severe back/side/abdominal/groin pain, fever, chills, painful/frequent urination, bloody/pink urine). A small number of people who take anticonvulsants for any condition (such as seizures, bipolar disorder, pain) may experience depression, suicidal thoughts/attempts, or other mental/mood problems. Tell your doctor right away if you or your family/caregiver notice any unusual/sudden changes in your mood, thoughts, or behavior including signs of depression, suicidal thoughts/attempts, thoughts about harming yourself.
