Read this Medication Guide before you start taking Trokendi XR® and each time you get a refill. There may be new information. This information does not take the place of talking to your healthcare provider about your medical condition or treatment. If you have any questions about Trokendi XR®, talk to your healthcare provider or pharmacist.

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.

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.
