Trokendi XR

Generic name: topiramate

What is Trokendi XR?

Trokendi XR is a prescription medicine used:

  • to treat certain types of seizures (partial onset seizures and primary generalized tonic-clonic seizures) in people 6 years and older,
  • with other medicines to treat certain types of seizures (partial onset seizures, primary generalized tonic-clonic seizures, and seizures associated with Lennox-Gastaut syndrome) in adults and children 6 years and older
  • to prevent migraine headaches in adults and adolescents 12 years of age and older.

What is the most important information I should know about Trokendi XR?

Take Trokendi XR capsules whole. Do not sprinkle Trokendi XR on food, or break, crush, dissolve, or chew Trokendi XR capsules before swallowing. If you cannot swallow Trokendi XR capsules whole, tell your healthcare provider. You may need a different medicine.

Do not drink alcohol within 6 hours prior to and 6 hours after Trokendi XR administration.

Trokendi XR may cause eye problems. Serious eye problems include:

  • any sudden decrease in vision with or without eye pain and redness,
  • a blockage of fluid in the eye causing increased pressure in the eye (secondary angle closure glaucoma).
  • These eye problems can lead to permanent loss of vision if not treated.
  • You should call your healthcare provider right away if you have any new eye symptoms, including any new problems with your vision.

Trokendi XR may cause decreased sweating and increased body temperature (fever). People, especially children, should be watched for signs of decreased sweating and fever, especially in hot temperatures. Some people may need to be hospitalized for this condition. If a high fever, a fever that does not go away, or decreased sweating develops, call your healthcare provider right away.

Trokendi XR can increase the level of acid in your blood (metabolic acidosis). If left untreated, metabolic acidosis can cause brittle or soft bones (osteoporosis, osteomalacia, osteopenia), kidney stones, can slow the rate of growth in children, and may possibly harm your baby if you are pregnant. Metabolic acidosis can happen with or without symptoms. Sometimes people with metabolic acidosis will:

  • feel tired
  • not feel hungry (loss of appetite)
  • feel changes in heartbeat
  • have trouble thinking clearly

Your healthcare provider should do a blood test to measure the level of acid in your blood before and during your treatment with Trokendi XR. If you are pregnant, you should talk to your healthcare provider about whether you have metabolic acidosis.

Like other antiepileptic drugs, Trokendi XR may cause suicidal thoughts or actions in a very small number of people, about 1 in 500.

Call a healthcare provider right away if you have any of these symptoms, especially if they are new, worse, or worry you:

  • thoughts about suicide or dying
  • attempts to commit suicide
  • new or worse depression
  • new or worse anxiety
  • feeling agitated or restless
  • panic attacks
  • trouble sleeping (insomnia)
  • new or worse irritability
  • acting aggressive, being angry, or violent
  • acting on dangerous impulses
  • an extreme increase in activity and talking (mania)
  • other unusual changes in behavior or mood

Do not stop Trokendi XR without first talking to a healthcare provider.

  • Stopping Trokendi XR suddenly can cause serious problems.
  • Suicidal thoughts or actions can be caused by things other than medicines. If you have suicidal thoughts or actions, your healthcare provider may check for other causes.

How can I watch for early symptoms of suicidal thoughts and actions?

  • Pay attention to any changes, especially sudden changes, in mood, behaviors, thoughts, or feelings.
  • Keep all follow-up visits with your healthcare provider as scheduled.
  • Call your healthcare provider between visits as needed, especially if you are worried about symptoms.

Trokendi XR can harm your unborn baby.

  • If you take Trokendi XR during pregnancy, your baby has a higher risk for birth defects called cleft lip and cleft palate. These defects can begin early in pregnancy, even before you know you are pregnant.
  • Cleft lip and cleft palate may happen even in children born to women who are not taking any medicines and do not have other risk factors.
  • There may be other medicines to treat your condition that have a lower chance of birth defects.
  • All women of childbearing age should talk to their healthcare providers about using other possible treatments instead of Trokendi XR. If the decision is made to use Trokendi XR, you should use effective birth control (contraception) unless you are planning to become pregnant. You should talk to your doctor about the best kind of birth control to use while you are taking Trokendi XR.
  • Tell your healthcare provider right away if you become pregnant while taking Trokendi XR. You and your healthcare provider should decide if you will continue to take Trokendi XR while you are pregnant.
  • If you take Trokendi XR during pregnancy, your baby may be smaller than expected at birth. The long-term effects of this are not known. Talk to your healthcare provider if you have questions about this risk during pregnancy.
  • Metabolic acidosis may have harmful effects on your baby. Talk to your healthcare provider if Trokendi XR has caused metabolic acidosis during your pregnancy.
  • Pregnancy Registry: If you become pregnant while taking Trokendi XR, talk to your healthcare provider about registering with the North American Antiepileptic Drug Pregnancy Registry. You can enroll in this registry by calling 1-888-233-2334. The purpose of this registry is to collect information about the safety of Trokendi XR and other antiepileptic drugs during pregnancy.

What should I tell my healthcare provider before taking Trokendi XR?

Before taking Trokendi XR, tell your healthcare provider about all of your medical conditions, including if you:

  • have or have had depression, mood problems, or suicidal thoughts or behavior
  • have kidney problems, kidney stones, or are getting kidney dialysis
  • have a history of metabolic acidosis (too much acid in the blood)
  • have liver problems
  • have weak, brittle or soft bones (osteomalacia, osteoporosis, osteopenia, or decreased bone density)
  • have lung or breathing problems
  • have eye problems, especially glaucoma
  • have diarrhea
  • have a growth problem
  • are on a diet high in fat and low in carbohydrates, which is called a ketogenic diet
  • are having surgery
  • are pregnant or plan to become pregnant
  • are breastfeeding. Trokendi XR passes into your breast milk. Breastfed babies may be sleepy or have diarrhea. It is not known if the Trokendi XR that passes into breast milk can cause other serious harm to your baby. Talk to your healthcare provider about the best way to feed your baby if you take Trokendi XR.

Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. Especially, tell your healthcare provider if you take:

  • Valproic acid (such as Depakene or Depakote)
  • any medicines that impair or decrease your thinking, concentration, or muscle coordination
  • birth control pills. Trokendi XR may make your birth control pills less effective. Tell your healthcare provider if your menstrual bleeding changes while you are taking birth control pills and Trokendi XR.

Ask your healthcare provider if you are not sure if your medicine is listed above.

Know the medicines you take. Keep a list of them to show your healthcare provider and pharmacist each time you get a new medicine. Do not start a new medicine without talking with your healthcare provider.

  • Take Trokendi XR exactly as prescribed.
  • Your healthcare provider may change your dose. Do not change your dose without talking to your healthcare provider.

  • Talk to your health care provider on what you should do if you miss a dose.
  • Do not stop taking Trokendi XR without talking to your healthcare provider. Stopping Trokendi XR suddenly may cause serious problems.
