IMPORTANT SAFETY INFORMATION

CONTRAINDICATIONS

  • Trokendi XR is contraindicated in patients with recent alcohol use (within 6 hours prior to and 6 hours after Trokendi XR use). 

WARNINGS & PRECAUTIONS

  • A syndrome consisting of acute myopia associated with secondary angle closure glaucoma has been reported in patients receiving topiramate. Symptoms can include acute onset of decreased visual acuity and/or ocular pain, myopia, anterior chamber shallowing, ocular hyperemia, and increased intraocular pressure. Symptoms typically occur within 1 month of initiating topiramate therapy. The primary treatment to reverse symptoms is discontinuation of Trokendi XR as rapidly as possible. Elevated intraocular pressure of any etiology, if left untreated, can lead to serious sequelae including permanent vision loss.
  • Visual field defects (independent of elevated intraocular pressure) have been reported in patients receiving topiramate. In clinical trials, most events were reversible after topiramate discontinuation. If problems occur at any time during topiramate treatment, consider discontinuation of the drug.
  • Oligohydrosis resulting in hospitalization has been reported in some cases in association with topiramate use. The majority of reports have been in pediatric patients. Patients, especially pediatric patients, should be monitored closely for evidence of decreased sweating and increased body temperature, especially in hot weather. Caution should be used when Trokendi XR is prescribed with other drugs that predispose patients to heat-related disorders.
  • Hyperchloremic, non-anion gap, metabolic acidosis has been reported in adults and pediatric patients treated with topiramate. This metabolic acidosis is caused by renal bicarbonate loss due to the inhibitory effect of topiramate on carbonic anhydrase. Conditions that predispose patients to acidosis may be additive to the bicarbonate-lowering effects of topiramate. Although Trokendi XR is not approved for children under 6 years of age, a study of topiramate as adjunctive treatment in patients under 2 produced metabolic acidosis of a notably greater magnitude than in older children and adults. Measurement of baseline and periodic serum bicarbonate during topiramate treatment is recommended. If metabolic acidosis develops and persists, consideration should be given to reducing the dose or discontinuing topiramate. The incidence of persistent decreases in serum bicarbonate in placebo-controlled trials with immediate-release topiramate for adults for prophylaxis of migraine was higher than in the epilepsy controlled trials, and higher in adolescents than adults.
  • In vitro data show that, in the presence of alcohol, the pattern of topiramate release from Trokendi XR capsules is significantly altered. Alcohol use should be completely avoided within 6 hours prior to and 6 hours after Trokendi XR administration.
  • Antiepileptic drugs (AEDs) increase the risk of suicidal thoughts or behavior in patients taking these drugs for any indication. Patients treated with any AED, including Trokendi XR for any indication, should be monitored for the emergence or worsening of depression, suicidal thoughts or behavior, and/or any unusual changes in mood or behavior. Anyone prescribing Trokendi XR must balance the risk of suicidal thoughts or behavior with the risk of untreated illness. Many illnesses for which antiepileptic drugs are prescribed are themselves associated with morbidity and mortality and an increased risk of suicidal thoughts and behavior. Should suicidal thoughts and behavior emerge during Trokendi XR treatment, the prescriber needs to consider whether the emergence of these symptoms in any given patient may be related to the illness being treated.
  • Immediate-release topiramate can cause, and therefore Trokendi XR is expected to cause cognitive/neuropsychiatric adverse reactions. In adults, the most frequent of these can be classified into three general categories: cognitive-related dysfunction, psychiatric/behavioral disturbances, and somnolence or fatigue.
  • Topiramate can cause fetal harm when administered to a pregnant woman. Use during pregnancy and data from pregnancy registries indicate that infants exposed to topiramate in utero can have increased risk of cleft lip and/or cleft palate, and for being small for gestational age. Trokendi XR should only be used during pregnancy if the potential benefit outweighs the potential risk. Patients should be informed of the potential hazard to the fetus.
  • Antiepileptic drugs, including Trokendi XR, should be gradually withdrawn to minimize the potential for seizures or increased seizure frequency.
  • Hyperammonemia with and without encephalopathy has been observed in post-marketing reports in patients who were taking topiramate with or without concomitant valproic acid (VPA); hyperammonemia appears more common when used concomitantly with VPA. Although Trokendi XR is not indicated for use in infants or toddlers, topiramate with concomitant VPA produced a dose-related increase in hyperammonemia in this population.
  • The concomitant use of Trokendi XR with any other drug producing metabolic acidosis, or potentially in patients on a ketogenic diet, may increase the risk of kidney stone formation and should therefore be avoided.
  • Hypothermia has been reported in association with topiramate use with concomitant valproic acid (VPA) both in the presence and in the absence of hyperammonemia. Consideration should be given to stopping topiramate or valproate in patients who develop hypothermia; clinical management should include examination of blood ammonia levels.
  • Topiramate is a CNS depressant. Concomitant administration of topiramate with other CNS depressant drugs can result in significant CNS depression. Patients should be watched carefully when Trokendi XR is coadministered with other CNS depressant drugs.

DOSING GUIDELINES & CONSIDERATIONS

  • Refer to the Trokendi XR DOSAGE AND ADMINISTRATION section of the full prescribing information for recommended dosing guidelines for Trokendi XR.
  • In patients with renal impairment (creatinine clearance less than 70 mL/min/1.73 m2), one-half of the usual adult dose is recommended. Such patients will require a longer time to reach steady-state at each dose.
  • In patients undergoing hemodialysis, to avoid rapid drops in topiramate plasma concentration, a supplemental dose of topiramate may be required. The actual adjustment should take into account the duration of dialysis period, clearance rate of the dialysis system being used, and the effective renal clearance of topiramate in the patient being dialyzed.
  • Trokendi XR can be taken without regard to meals. Swallow capsule whole and intact. Do not sprinkle on food, chew, or crush.

ADVERSE REACTIONS

  • Trokendi XR has not been studied in a randomized, placebo-controlled phase 3 clinical study; however, it is expected that Trokendi XR would produce a similar adverse reaction profile as that of immediate release topiramate. See the ADVERSE REACTIONS section of the Trokendi XR full prescribing information for further adverse reaction rates from the clinical trials conducted under widely varying conditions.
  • In migraine prophylaxis trials of 100 mg immediate-release topiramate, the most common adverse reactions in adults that were higher than placebo were paresthesia (51% v 6%, 100 mg/day v placebo), anorexia (15% v 6%), upper respiratory tract infection (14% v 12%), weight decrease (9% v 1%), taste perversion (8% v 1%), diarrhea (11% v 4%), difficulty with memory (7% v 2%), hypoaesthesia (7% v 2%), nausea (13% v 8%) and abdominal pain (6% v 5%).

INDICATION

  • Trokendi XR (topiramate) extended-release capsules are indicated for prophylaxis of migraine headaches in patients 12 years of age and older.
