Reviewed by: HU Medical Review Board | Reviewed March 2022 | Last updated: June 2022

Trokendi XR™ (topiramate) is indicated for the prophylaxis of migraine in patients 12 years of age and older. It is taken by mouth as prophylactic therapy to reduce migraine frequency. For those with frequent migraine attacks or migraine that do not respond to acute treatment, preventive medications can be important.

Trokendi XR is an extended-release formulation of topiramate, the same medication in Topamax®.

What are the ingredients in Trokendi XR?

The active ingredient in Trokendi XR is topiramate.

How does Trokendi XR work?

The precise way Trokendi XR works to prevent migraine is unknown. It is thought that the medication blocks sodium channels and increases the activity of certain neurotransmitters in the brain. This likely inhibits some of the receptors in nerve cells, which reduce electrical activity and contribute to the development of migraine.

What are the possible side effects of Trokendi XR?

Many clinical trials evaluated the safety and efficacy of Trokendi XR. The most common side effects experienced by those taking Trokendi XR include:

  • Hypoesthesia
  • Taste disturbances
  • Numbness or tingling in the fingers and toes (paresthesia)
  • Anorexia
  • Weight loss
  • Diarrhea
  • Abdominal pain
  • Nausea
  • Upper respiratory infections
  • Speech and memory difficulties

This is not an exhaustive list of all potential side effects of Trokendi XR. For more information, consult your doctor or healthcare provider. If you notice any new or worsening side effects when taking Trokendi XR, contact your doctor or healthcare provider immediately.
